@@mm-hl7gh That is not true, F does what you described. J cuts through the mesh surface and integrates the edge into the topology. It acts just like the knife tool between the two selected points, except it's safer because the knife tool sometimes gets subtly misaligned and creates two vertices where there should be one. Use J instead of the knife tool wherever you're doing simple cuts. Knife is good for cutting more complex shapes.
@@mm-hl7gh you are mistaken, sir. Using J does create the necessary vertices in the intermediate faces between the selected points. It is the F key the one that creates the disconnected edge.
@@Keavon If the knife tool is inaccurate, adjust your view clip start and end. Clip start must not be too small. Clip end must not be too large. It's weird behavior but you can verify that it works with a simple plane.

The ideas described in this video are good tools to have in your toolset, but it’s far from a one-size-fits-all solution to all topology problems. You need to be careful about introducing poles, as those affect shading and create convergence points or “pinches” in topology when subdivided.

Yesterday I was trying to put a round hole in a sphere, using similar method, but failed and then failed and failed again. Do make similar videos, specially putting a round hole in a sphere. I will appriciate similar videos, as they will save me later when I am stuck.

I paused at 0:08 and tried to recreate this. I had a hand with like 15 vertices loop trying to connect it to 6 vertices loop of the arm. I somehow managed to reduce 15~ vertices to 8 vertices and 6 vertices I increased to 8. Such satisfaction when I connected them! Although somehow the topology doesn't feel to look very good, but the overall result satisfies me. Thank you very much!
I'm just at that moment when I'm getting into hard surface modeling and becoming aware of problems like this. Your tutorial will surely be useful in the future.
I remember coming to this video from a question I asked in reddit, someone helped me to this, and then i also shared this video a ton to whoever has asked me help about topology, people only do this when videos are NOT crap, this video is precious. ❤
VerticalWit when he starts making cuts on the “ribbon” (the plane on the left) he shows a short process for increasing or decreasing the number of faces in different parts of a model. Off the top of my head, this kind of topology management is important for several reasons. 1. Keeping poly counts down. This is not as important these days, but still a concern for low-resource gaming. 2. For avoiding having unnecessary faces generated far away from the place you actually need them, and keeping the model “clean” of excess faces. This helps a lot when animating and weight painting, since having more or less faces densely packed in an area affects the way a mesh deforms under an armature, or has particles emitted from it in some particle systems. 3. Note how every face he drew with his method is a quad. Using his method specifically, you can still use loop cuts that will go all the way around a model, and other modifiers/transforms like subsurface will continue to work well, since you’re not including random triangles or n-gons in the mesh. This property, of maintaining the path of loops of connected faces, is what is being shown in the thumbnail of this video.
I've had problems with multiple edge loops going around my models since I started and couldn't figure out how you actually should do it. This really helped me thank you.
This is probably the single most important video I've seen with regards to mesh modelling, I just wish I saw it earlier. Now I need to go and practice it over and over until it becomes second nature. I just want to thank you from the bottom of my heart for explaining it in such a simple way! It seems so obvious now and I feel stupid for not being able to figure it out myself.
I am a total beginner at 3D art but I just know this is one of those art videos that I would watch as an expert and go "Wow I wish I had this tutorial when I was starting out"
Things to keep in mind. Long and thin polygons will trip up Gouraud shader. It's not usually relevant today, but it was super relevant when you were targeting Dreamcast, PS2, Gamecube era hardware and may still be relevant when targetting low-end mobile platforms. More relevantly for today, Catmull-Clark subdivision trips up on triangles, so you're good on avoiding them. However it also trips up on odd-valence vertices. Normally in a pure quad mesh, every vertex has 4 edges connected to it, so the valence of the vertex is 4. You have built a bunch of 3- and 5-valence vertices in here, which are usually not as bad as tris outright, but will still cause waviness in the subdivided mesh output. Since pure 4-valence quad topologies are generally impractical, there's often no substitute for just winging it and taking the waviness and letting it be the model feature where necessary, building the topology adjustment around there. I'm also not convinced that the industry should stick to Catmull-Clark subdivision invented in the 70s. I my experiments, i had the impression (but no mathematical proof) that the behaviour of the subdivision could be improved by introducing normal-based displacements that would depend on local topology and would also help the subdivision be somewhat volume preserving, since Catmull-Clark tends to deflate a lot. It's not like research ended there, there was Stam/Loop 2002 "Quad/Triangle Subdivision ".
Does anybody bother with Gouraud shading any more, when Phong shading is superior and doesn’t cost much on modern hardware? Easy enough to add extra loop cuts next to the EVs to constrain their effect. Also, your idea about normal-based displacements reminds me of Blender’s “weighted-normal” modifier. Worth giving that a try.
Lawrence D’Oliveiro Phong is an old term not really used anymore. It’s just vertex based shading or fragment shading whatever that shading is doing. That said. Normal light linear fragment shaded today is not more expensive than vertex shading.
I didn't realize how much I needed this explanation. There's no doubt that simplicity is the maximum sophistication. Thank you very much, I'm saving the thumbnail so I can always go back to remember exactly how to deal with topology.
I am glad i found this it was very helpful Iam using blender from a month And after reading comments i think iam lucky that i did not found it after server year of experience Its just a month and i was searching for retopology techniques and i found this most helpful video THANKS A LOT
I've been doing this for a while now and I must say that it is extremely useful, BUT sometimes it completely destroys the flow and also sometimes there is a problem with the subdivision. You should use this on relatively flat or empty surfaces. For instance, an ear is more detailed, than the head, but at the same time there is a flat space before the ear begins, but a tear duct might be actually better with triangles, since there is detail all around the tear duct too, which'd be destroyed in the process.
Finally, a comment from someone who has real experience in SubD modelling.) All these methods to end loop cuts with a quad has been used for years but they are still rarely used as they usually produce bad shading.
Thank you. It’s not nearly as simple as this video makes it out to be. For one, you’re altering the number of edge loops on either side of the topology group in question. You’re also introducing poles, which isn’t something to be cavalier about, as they’re going to change shading and create “pinch” in your topology, which isn’t always desirable. So no, this isn’t a one-size-fits-all solution to any topology problem.
Exactly. The only topology you'll ever need! To solve simple joining problems on planes and flat shaded meshes, maybe.... If that was all topology was, we'd have had awesome, fully automated retopo tools a decade ago.
Lmao, yeah, towards the end of the video I've been saying out loud at my screen: "yeah cool and now subdivide it, go ahead and subdivide, like you showed at the beginning". Who really does hardsurface today and not use subdivision tools?
@@vladimirlavrentyev9206 I'm a blender noob. What would actually happen if we never used the video's method and jsut had loop cuts going around the full model?
I've been looking for this exact knowledge for years. I kind of found the 1 to 3 method once, but 1 to 2 was always nightmare for me. I'm so glad YT recommended me this.
Great tutorial, ive spent literally hours making sure my edge loops did make it round my models so they all connected up. Now I can just cut them off at source. Cheers bud.
ive come back to this video a few times just to keep this straight in my head. so simple but when modelling i get so confused on topology. thanks for uploading this video!
Newbie to 3D modelling. I had no idea why this was supposed to be helpful until, literally, the last thirty seconds when the lightbulb went off. Great video.
Just recently I started trying out blender and did a really wonderful donut. Just last night I went full on solo mode and tried to model my own phone. And oh boy! How badly I need this video as the loop cuts are everywhere! THANK YOU!
Im gonna have to watch this like a billion more times because i dont even know what topology is but hopefully this will help fix some problems i find in my models.
I think the easiest way to think about it is this: Each quad has 2 edges perpendicular to the direction of the topology which i call "front egdes" and the other edges I call "side egdes". Whenever you change the amount of faces, you turn one edge to be diagonal making up a front edge for one and a side edge for another quad. So if you want one more face, make one side edge to a front edge and you have one more front edge, hence one more quad, or reverse etc.
While applying this method isn't going to be simple 100% of the time, the principle is what matters. Don't think about deleting this video... regardless of its quality, you are implanting an important understanding of quads and polys and a smart way of thinking about the topology itself. Thank you!
A true master of toplogy, respect and salute. Thank you so much for solving the most difficult mystery for the NOOBIES, trully appreciated and will forever remember the NAME, of the master. Thank you.
@@DECODEDVFX Oh man, you have no idea... So many times I've stared at my pristine model for ten minutes before giving up and hitting ctrl R knowing that the topology will never be perfect again but consoling myself that this huge compromise is needed keep ngons off my mesh. I owe you a pint.
@@DECODEDVFX Tell me one thing. I've thought a lot about this. What is your take on starting from a primative and dicing vs starting from a plane and extruding? When I first look at an object this is the first decision I take (I have a bias to primative because you can control symmetry more precisely) but - say if I'm making a car - I'll choose planes because I know I'll need to get the edge flow of the topology to match the fundamental geometry of the object. Although, I'm thinking that what you've taught me here may change that. What's your approach?
I generally start with whichever default shape most closely resembles the object I'm modeling - usually a cube or cylinder. I hardly ever model from a plane.
I think this is more on the beginner level not really the intermediate level. As you get more advanced, it's important to understand how to use poles to create pinch points and direct edge flow. I think an intermediate exercise would be how to use the minimal amount of faces to achieve the same effect.
Thank you so much for posting this video. I'm in my 40s, have ADHD and am attempting 3D modeling for the second time in my life. The first time was prior to medication, with poor tech that would crash and with software that was spline-based so dealing with the topology was EVERYTHING. As I have picked up Blender, I have had this distracting, anxiety in the back of my head that has been a roadblock. TOPOLOGY. I am someone that needs to know a little more about the machinery before I can feel comfortable using it and unfortunately, no-one titles youtube videos, HEY, the thing with the shapes and creasing and the part-mathy, part-real world stuff, I CAN HELP WITH THAT. After watching your video and with a rudimentary knowledge of anatomy it makes sense. You don't go from your fingers to your forearm with five bones. It's inefficiency use of energy and probably shitty mechanics. You build down with multiple bones decreasing and increasing based on the needs for flexibility until you get to the structure where all you need is rigid support. We of the neurodivergent thank you.
My Lord, I can't thumbsup this enough. I wish this was shown to me back in 1.9 when I started playing with Blender and all my models had topology running all over the model because I couldn't make enough geometry for the mouth, the ears, the fingers, feet... I spent so much time inquiring around the forums back in them and nobody told me anything to solve my problem. Damn, so uber duper useful! More THUMBS 👍👍👍👍👍👍👍👍👍👍👍THANK YOU SIR!
I am a beginner. While your video wasn't easy for me, but it definately got me one step closer to understanding topology. I kind of get the concept of disconnecting the side that doesn't need too much toplogy from the one that needs it with quads. I think it's a big lesson for me, so thank you!
I'm just a beginner and now I know how much I'm a beginner, since I did not even understand what was the problem, let alone all the further explanation. Lots of like so it is probably useful for people that are experts. Good luck to everyone. I clicked on the video because I wanted to learn more about topology...
I remember watching a video of someone modeling the Sanic. He made a lopp cut just above the eyee for the eyeball to fit and this loop cut had gone all the way down through neck, around the body and then back to the neck and ended above the other eye. It was hilarious.
At first I didn't quite get the point of what you were saying. I was like "at 1:27 just dissolve all those loop cuts." It wasn't until I got to the end (and tried it myself) that I realized that doing it your way results in all quads!
@@TroglodyJeej you can loop cut through them easier. With a square or a quad, going through the "middle of it" is easy because a line can just go in one edge and out the opposite. If you go in one edge of a triangle or pentagon, there are two possible edges it can come out of. This means Blender gets confused if you try to loop cut (CTRL-R) it. Also I think quads and squares deform much easier to it makes animation better. (Ofc when it's rendered it's turned into triangles anyway, but at that point you're done working with it so it doesn't matter)
@@Mayeru just do the donut tutorial, trust me it'll save your life if you're actually ever expecting to use blender. Patience and that tutorial will help a lot. It taught me a lot of the basics.
@@Mayeru blender guru’s world famous donut tutorial, that’s the holy grail of starting points for many blender users. Blender guru is truly one of the best, takes the time to explain why he does what and assumed you knew nothing about blender before doing that particular tutorial. So if you’re ever going to use blender in life, be it this day, month, or some other year, just do yourself the major favor of starting there. Blender guru commented on this video too, so you can see that up there if you want.
Dude this video right here helps so much nobody explains how they come to their conclusions and make it really hard to understand the process to be able to come up with these solutions for yourself they never explain what logic they are following thanks a bunch
as a beginner with no concept of this, I gotta say, this is a game changer. I've never modeled anything too complex and one of the main reasons for that is because once I started getting detailed and adding loop cuts and seeing all these loop cuts cutting around my whole model with no real purpose in most places I knew I was doing something wrong but I didn't know what, now I know. Thank you for this quick guide, totally ups my game.
As a visual person, this literally solves the topology problem that had prohibited me from fully understanding what I'm doing when making 3D models and stuff starts getting weird. This is a godsend; the thumbnail graphic alone says so much! Thank you for this video so much!
Thank you! I have begun modelling since 2 months and people kept telling me "the topology here and here is bad" but they never told me *why* it's bad. At least thanks to this video now I have half idea how to split faces correctly.

I somehow managed to reduce 15~ vertices to 8 vertices and 6 vertices I increased to 8. Such satisfaction when I connected them! Although somehow the topology doesn't feel to look very good, but the overall result satisfies me. Thank you very much!
I'm just at that moment when I'm getting into hard surface modeling and becoming aware of problems like this. Your tutorial will surely be useful in the future.
I remember coming to this video from a question I asked in reddit, someone helped me to this, and then i also shared this video a ton to whoever has asked me help about topology, people only do this when videos are NOT crap, this video is precious. ❤
Why am I here? I don't even do how to model.
I can't understand but it seems very interesting.
same here, was wondering why it is a problem if there are these loop cut thingies
@@RagbagMcShag it's because it adds loops in places unneeded and just clutters your model up plus when you want to smooth the model it can deform it
@@Ossie_Gaming Oh interesting, thanks for the info
Could some topology dude explain to us plebs here why this in the video is so awesome?
VerticalWit when he starts making cuts on the “ribbon” (the plane on the left) he shows a short process for increasing or decreasing the number of faces in different parts of a model. Off the top of my head, this kind of topology management is important for several reasons.
1. Keeping poly counts down. This is not as important these days, but still a concern for low-resource gaming.
2. For avoiding having unnecessary faces generated far away from the place you actually need them, and keeping the model “clean” of excess faces. This helps a lot when animating and weight painting, since having more or less faces densely packed in an area affects the way a mesh deforms under an armature, or has particles emitted from it in some particle systems.
3. Note how every face he drew with his method is a quad. Using his method specifically, you can still use loop cuts that will go all the way around a model, and other modifiers/transforms like subsurface will continue to work well, since you’re not including random triangles or n-gons in the mesh. This property, of maintaining the path of loops of connected faces, is what is being shown in the thumbnail of this video.
I've had problems with multiple edge loops going around my models since I started and couldn't figure out how you actually should do it. This really helped me thank you.
This is probably the single most important video I've seen with regards to mesh modelling, I just wish I saw it earlier. Now I need to go and practice it over and over until it becomes second nature. I just want to thank you from the bottom of my heart for explaining it in such a simple way! It seems so obvious now and I feel stupid for not being able to figure it out myself.
Been having trouble with my first model alone (with no tutorials) and you pretty much answered my problem after hours of trouble. Thank you sir!
I am a total beginner at 3D art but I just know this is one of those art videos that I would watch as an expert and go "Wow I wish I had this tutorial when I was starting out"
this video literally opened the door for 3D modelling for me, i just wanted to let you know how great of a video this is
Thank you!
Things to keep in mind. Long and thin polygons will trip up Gouraud shader. It's not usually relevant today, but it was super relevant when you were targeting Dreamcast, PS2, Gamecube era hardware and may still be relevant when targetting low-end mobile platforms.
More relevantly for today, Catmull-Clark subdivision trips up on triangles, so you're good on avoiding them. However it also trips up on odd-valence vertices. Normally in a pure quad mesh, every vertex has 4 edges connected to it, so the valence of the vertex is 4. You have built a bunch of 3- and 5-valence vertices in here, which are usually not as bad as tris outright, but will still cause waviness in the subdivided mesh output. Since pure 4-valence quad topologies are generally impractical, there's often no substitute for just winging it and taking the waviness and letting it be the model feature where necessary, building the topology adjustment around there.
I'm also not convinced that the industry should stick to Catmull-Clark subdivision invented in the 70s. I my experiments, i had the impression (but no mathematical proof) that the behaviour of the subdivision could be improved by introducing normal-based displacements that would depend on local topology and would also help the subdivision be somewhat volume preserving, since Catmull-Clark tends to deflate a lot. It's not like research ended there, there was Stam/Loop 2002 "Quad/Triangle Subdivision
".
Well hurry up and develop a subdiv plugin for us all to use then dammit lol. XD
Does anybody bother with Gouraud shading any more, when Phong shading is superior and doesn’t cost much on modern hardware?
Easy enough to add extra loop cuts next to the EVs to constrain their effect.
Also, your idea about normal-based displacements reminds me of Blender’s “weighted-normal” modifier. Worth giving that a try.
Lawrence D’Oliveiro Phong is an old term not really used anymore. It’s just vertex based shading or fragment shading whatever that shading is doing.
That said. Normal light linear fragment shaded today is not more expensive than vertex shading.
You got to be kidding me, right? en.wikipedia.org/wiki/Phong_shading
Wow I have been modeling for 19 years and this is best and fastest video on this topic I have seen! Very nice.
I didn't realize how much I needed this explanation. There's no doubt that simplicity is the maximum sophistication.
Thank you very much, I'm saving the thumbnail so I can always go back to remember exactly how to deal with topology.
i've been using blender for years and i didn't believe the title but wow, i really needed this.
I am glad i found this
it was very helpful
Iam using blender from a month
And after reading comments i think iam lucky that i did not found it after server year of experience
Its just a month and i was searching for retopology techniques and i found this most helpful video
THANKS A LOT
I started learn blender a few month ago. I just need to say this video is life saver for me. Thanks a lot.
It's the best and simplest explanation about topology I ever found in internet. Thank you!
I've watched this video at least 7 to 10 times and it finally clicked today when I saw the pattern. Excellent video and thank you!
I've been doing this for a while now and I must say that it is extremely useful, BUT sometimes it completely destroys the flow and also sometimes there is a problem with the subdivision. You should use this on relatively flat or empty surfaces. For instance, an ear is more detailed, than the head, but at the same time there is a flat space before the ear begins, but a tear duct might be actually better with triangles, since there is detail all around the tear duct too, which'd be destroyed in the process.
Finally, a comment from someone who has real experience in SubD modelling.) All these methods to end loop cuts with a quad has been used for years but they are still rarely used as they usually produce bad shading.
Thank you. It’s not nearly as simple as this video makes it out to be. For one, you’re altering the number of edge loops on either side of the topology group in question. You’re also introducing poles, which isn’t something to be cavalier about, as they’re going to change shading and create “pinch” in your topology, which isn’t always desirable. So no, this isn’t a one-size-fits-all solution to any topology problem.
Exactly. The only topology you'll ever need! To solve simple joining problems on planes and flat shaded meshes, maybe.... If that was all topology was, we'd have had awesome, fully automated retopo tools a decade ago.
Lmao, yeah, towards the end of the video I've been saying out loud at my screen: "yeah cool and now subdivide it, go ahead and subdivide, like you showed at the beginning". Who really does hardsurface today and not use subdivision tools?
@@vladimirlavrentyev9206 I'm a blender noob. What would actually happen if we never used the video's method and jsut had loop cuts going around the full model?
I've been looking for this exact knowledge for years. I kind of found the 1 to 3 method once, but 1 to 2 was always nightmare for me. I'm so glad YT recommended me this.
Great tutorial, ive spent literally hours making sure my edge loops did make it round my models so they all connected up. Now I can just cut them off at source. Cheers bud.
ive come back to this video a few times just to keep this straight in my head. so simple but when modelling i get so confused on topology. thanks for uploading this video!
Dude, I randomly clicked on this. I have no regrets. This will come in handy. Thank you.
Newbie to 3D modelling. I had no idea why this was supposed to be helpful until, literally, the last thirty seconds when the lightbulb went off. Great video.
this is one of the most valuable tutorials for topology. it helped me alot in my workflow. thanks!
Just recently I started trying out blender and did a really wonderful donut.
Just last night I went full on solo mode and tried to model my own phone. And oh boy! How badly I need this video as the loop cuts are everywhere! THANK YOU!
Im gonna have to watch this like a billion more times because i dont even know what topology is but hopefully this will help fix some problems i find in my models.
I would've killed for this simple explanation when I was working in my modeling class.
I think the easiest way to think about it is this: Each quad has 2 edges perpendicular to the direction of the topology which i call "front egdes" and the other edges I call "side egdes". Whenever you change the amount of faces, you turn one edge to be diagonal making up a front edge for one and a side edge for another quad. So if you want one more face, make one side edge to a front edge and you have one more front edge, hence one more quad, or reverse etc.
All I hear is: edge edge face edge quad quad lol (beginner here)
This comment made me understand not only the video itself, but why people use quads in the first place!
While applying this method isn't going to be simple 100% of the time, the principle is what matters. Don't think about deleting this video... regardless of its quality, you are implanting an important understanding of quads and polys and a smart way of thinking about the topology itself. Thank you!
A true master of toplogy, respect and salute. Thank you so much for solving the most difficult mystery for the NOOBIES, trully appreciated and will forever remember the NAME, of the master. Thank you.
Thank God RUclips didn't suggest me this video 5 years later, I really needed such explanation. Great video!
This is a great tutorial from you, that was straight to the point.
Even that single image in the intro has helped me a ton. Thanks so much for this.
Oh my god, this is life changing. I've watched it three times now.
Thank you so much man.
Thank you. Glad you found it helpful.
@@DECODEDVFX Oh man, you have no idea... So many times I've stared at my pristine model for ten minutes before giving up and hitting ctrl R knowing that the topology will never be perfect again but consoling myself that this huge compromise is needed keep ngons off my mesh.
I owe you a pint.
@@davidmurphy563 A lot of people struggle with good topology, including myself - so you're not the only one.
@@DECODEDVFX Tell me one thing. I've thought a lot about this. What is your take on starting from a primative and dicing vs starting from a plane and extruding?
When I first look at an object this is the first decision I take (I have a bias to primative because you can control symmetry more precisely) but - say if I'm making a car - I'll choose planes because I know I'll need to get the edge flow of the topology to match the fundamental geometry of the object. Although, I'm thinking that what you've taught me here may change that.
What's your approach?
I generally start with whichever default shape most closely resembles the object I'm modeling - usually a cube or cylinder. I hardly ever model from a plane.
This is the BEST topology video I've seen before! Short and understandable
I think this is more on the beginner level not really the intermediate level. As you get more advanced, it's important to understand how to use poles to create pinch points and direct edge flow. I think an intermediate exercise would be how to use the minimal amount of faces to achieve the same effect.
u cant head to intermediate level without this 😅😅
This series might be the very best topo guidance I've seen anywhere. Thanks so much for sharing.
Thank you so much for posting this video. I'm in my 40s, have ADHD and am attempting 3D modeling for the second time in my life. The first time was prior to medication, with poor tech that would crash and with software that was spline-based so dealing with the topology was EVERYTHING. As I have picked up Blender, I have had this distracting, anxiety in the back of my head that has been a roadblock. TOPOLOGY. I am someone that needs to know a little more about the machinery before I can feel comfortable using it and unfortunately, no-one titles youtube videos, HEY, the thing with the shapes and creasing and the part-mathy, part-real world stuff, I CAN HELP WITH THAT. After watching your video and with a rudimentary knowledge of anatomy it makes sense. You don't go from your fingers to your forearm with five bones. It's inefficiency use of energy and probably shitty mechanics. You build down with multiple bones decreasing and increasing based on the needs for flexibility until you get to the structure where all you need is rigid support. We of the neurodivergent thank you.
I second that
37, starting on round three myself. Keep on it mate, we'll get this eventually!
good for you! :)
My Lord, I can't thumbsup this enough. I wish this was shown to me back in 1.9 when I started playing with Blender and all my models had topology running all over the model because I couldn't make enough geometry for the mouth, the ears, the fingers, feet... I spent so much time inquiring around the forums back in them and nobody told me anything to solve my problem.
Damn, so uber duper useful! More THUMBS 👍👍👍👍👍👍👍👍👍👍👍THANK YOU SIR!
I just used this to make my first fork. Damn it's a sexy fork. Dat topology.
I am a beginner. While your video wasn't easy for me, but it definately got me one step closer to understanding topology. I kind of get the concept of disconnecting the side that doesn't need too much toplogy from the one that needs it with quads. I think it's a big lesson for me, so thank you!
Very underrated channel amazing videos, 1 minor thing to improve the videos on i would say is improving the background audio
Thank you. I now have a proper studio mic so the audio issues have been sorted.
I'm just a beginner and now I know how much I'm a beginner, since I did not even understand what was the problem, let alone all the further explanation. Lots of like so it is probably useful for people that are experts. Good luck to everyone.
I clicked on the video because I wanted to learn more about topology...
I remember watching a video of someone modeling the Sanic. He made a lopp cut just above the eyee for the eyeball to fit and this loop cut had gone all the way down through neck, around the body and then back to the neck and ended above the other eye. It was hilarious.
I've been doing 3D for about 5 years now and I've never seen something like this. Thank you!
At first I didn't quite get the point of what you were saying. I was like "at 1:27 just dissolve all those loop cuts."
It wasn't until I got to the end (and tried it myself) that I realized that doing it your way results in all quads!
Hi ! I'm still stuck on the same initial thought, what is so great about quads?
Is there cases where we're forced to reduce the number of faces manually like this?
@@TroglodyJeej you can loop cut through them easier.
With a square or a quad, going through the "middle of it" is easy because a line can just go in one edge and out the opposite.
If you go in one edge of a triangle or pentagon, there are two possible edges it can come out of. This means Blender gets confused if you try to loop cut (CTRL-R) it.
Also I think quads and squares deform much easier to it makes animation better.
(Ofc when it's rendered it's turned into triangles anyway, but at that point you're done working with it so it doesn't matter)
this was the thing that was missing in my life... after 10 years, somebody finally explained this like a normal person!
i didn 't understand anything but i'm still going to save this for whenever i start using blender.
Have you started Blender yet?
@@jaydenstorace3218 this is me from the future, i have not : ) i suck
@@Mayeru just do the donut tutorial, trust me it'll save your life if you're actually ever expecting to use blender. Patience and that tutorial will help a lot. It taught me a lot of the basics.
@@fadethecreator the donut tutorial? is it one of the quickstarts from Blender documentation?
@@Mayeru blender guru’s world famous donut tutorial, that’s the holy grail of starting points for many blender users. Blender guru is truly one of the best, takes the time to explain why he does what and assumed you knew nothing about blender before doing that particular tutorial. So if you’re ever going to use blender in life, be it this day, month, or some other year, just do yourself the major favor of starting there. Blender guru commented on this video too, so you can see that up there if you want.
Dude this video right here helps so much nobody explains how they come to their conclusions and make it really hard to understand the process to be able to come up with these solutions for yourself they never explain what logic they are following thanks a bunch
I've been avoiding learning this skill. Thanks for posting it!
Same here pal
I barely do any modelling, but thanks to RUclips now I know the solution to the problem I didn't knew I had.
This has baffled me for so long!. Thank you for explaining it so clearly :-)
Thanks :)
Me with modeling minecraft block models voxel by voxel by hand.
This might be the most important video I've watched since starting to learn Blender.
Glad to help
this amazing honestly. an eye opener for me. Thanks very much for this tip.
as a beginner with no concept of this, I gotta say, this is a game changer. I've never modeled anything too complex and one of the main reasons for that is because once I started getting detailed and adding loop cuts and seeing all these loop cuts cutting around my whole model with no real purpose in most places I knew I was doing something wrong but I didn't know what, now I know. Thank you for this quick guide, totally ups my game.
never delete this video
As a visual person, this literally solves the topology problem that had prohibited me from fully understanding what I'm doing when making 3D models and stuff starts getting weird. This is a godsend; the thumbnail graphic alone says so much! Thank you for this video so much!
Glad it helped!
...and it's actually a sub from me as well. I like where this is going and I'm pretty tired of donut gurus. Keep the great work!
Thank you!
Donut Guru... Ahahah ! Nice one.
g u r u s . nice
The thumbnail says everything already. Thank you for sharing.
Well done with a great practical example, thank you! Subbed.
Thanks!
Thank you! I have begun modelling since 2 months and people kept telling me "the topology here and here is bad" but they never told me *why* it's bad. At least thanks to this video now I have half idea how to split faces correctly.
This is genius! You're a genius!
Hardly a genius, but thank you!
That's what I like. Kick tutorial treating a general manner to approach a common issue. Brilliant!
i feel like a goldfish watching this because you explained everything beautifully but i'm still too ape brain to understand topology
2:20 onwards is pure gold. The entire video is but that part especially.
Well he didn't lie, my life has been changed and I am now illuminated with forbidden knowledge
You have totally made topology so much easier than anyone else. Thanks for this
Besr video i saw in a while, thank you i sub, liked and share! Keep making those short videos of topology fixing.
Thanks man.
This has been the best demo so far to explain philosophically the breakdown of 5-3-1-3-5 topology! I practicing now. Thanks!!!
that was very useful indeed, thank you
Thank you for explaining this, as someone that started learning blender a week ago this is a good habit to learn early.
I don't even know what topology is, how was I recommended this?
Blender has chosen you
i downloaded blender today since I heard filmic got integrated, now it shows me this, yeah okay i'll start blending
seems like Google is trying to manipulate people into certain topics/jobs..
