BETTER PERFORMANCE in Blender with the Decimate Modifier!
HTML-код
- Опубликовано: 12 июл 2024
- In this video, learn to use the decimate modifier for Blender to reduce the size and complexity of objects to improve performance!
Often, we'll use models inside of Blender that are just too complex - they have way more faces and vertices than they really need, which can really hurt your model performance on your computer.
This modifier gives you an easy way to reduce the number of edges/faces/vertices in your model!

Hi everyone! Let me know what you think about the decimate modifier in the comments below! :)
@thecgessentials sorry for the off topic question but do you know how to import fbx with imbeded textures?
opening the file does'nt show any textures..
Great video and tutorial. I think im winner of all sub problems 😂 I make mushroom and sub it 2 times i copy it i 6 mushrooms and make colection,that colection i copy 15 times and that 15 times i copy 3 more.times.. 3x45 + x6 more mushrooms ..810 copied mushrooms with sub lv 2 when i opet decimate modf it was in 1 colection over 4 mil faces and i got 3 colection,that was 12mil faces my pc crash and blender 😂
It's so cool!
It was really helpful. It was exactly what I was looking for. I wanted to upload a model to Pepacura to make a real 3D sculpture and the only way to do it was to decimate my model to get way fewer faces. Thank you, man.
For game models to get the most optimal results use planar, with the option that preserves your uv seams. Then select an angle that gives you an acceptable amount of detail. Place a triangulate modifier after.
This is actually such an under appreciated simple step to stop blender crashing...while everyone is focused on cutting down the esthetics...ur chopping down the base structure...well done buddy!
I notice every time I need some Blender info I end up coming back to you. Concise and clear, thank you. I was panicking about what I was going to do with my model that caused Blender to slow down severely. I used the decimate modifier and brought it down where it still looked good. Now I can even use duplicates of the object in my scene. Thank you, thank you, thank you!!!
I started using Blender in the last month. You’re videos are a wealth of knowledge.
Thank you CG for the best explantion of how to get vertex's numbers down, these other youtubers beat around the bush! you kept your vid/instructions simple and short, this helped alot man big ups
i love you for this - it made staying up till 3am fretting about a messy 2m triangle mess of a scan - wondering how i'd ever get anywhere with my pc moving at the rate of a snail , well worth it , thank you , your tutorials are spot on.
Another excellent CG Essentials tutorial. Many thanks.
Thank you so much! This is exactly what I needed. Very clear and understandable. I watched 2 videos before this from other people that I couldn't understand.
Do you not know who frecken helpful this is! Dude thank you! I always use subdivided to make my models but everytime I use it to animate it the bones never actually connect but because of this not only the model doesn’t change but it still looks nature! So thank you! Now my computer runs easier and faster, truly thank you!
Thank you for explaining all 3 decimate options! Saved my life! :D
That was ABSOLUTELY BRILLIANT! Thank you! I didn't think a newb like me would be able to understand this but I do! You explained it so clearly.
Thank god for this tutorial! I was having trouble with a model and I needed to find a way to simplify it. This was useful!
This is really helpful for game assets, especially creatures which are difficult to edit after subdivision surface and triangulation has applied.
Exactly!
What a completely clear and easy to follow and understand tutorial!
Very helpful, thank you so much for sharing your time and knowledge.
Whoah that PLANAR method just stopped me from ripping my hair out man. I was stuck trying to do UV work on a model that had waaaay too much topology, this is way better. You are a life saver. THANK YOU!
Thank you sir, this was really helpful! I appreciate how you compared the different methods of decimating and their effects on pre-applied materials. :)
Great straightforward demo and explanation- a game changer! Thanks!
Glad it was helpful!
This was super helpful to me in actually understanding the decimate modifier in Blender. Thank You for sharing.
Glad it was helpful!
This tutorial saved my model! Thank you for posting
Big help thank you very much. I love your tutorials.
Glad you like them!
Thank you! This video was super helpful
Brilliant video and thanks :D:D
Great JOB !
Awesome and thanks for the tutorial. 👍💯
Explaining the plane modifier saved so much time and effort on my avatar.
Congrats Thanks and that Silves One of my issues with my models regarding maintaining the UV Maps ,Many thanks again
thank you for this tutorial really needed it
Thank you so much for great tip. I appreciate your great content and great explanation
Nice tut. thanks
Thank you! Well done!
this has helped me so much with Importing my avatar onto the Quest. Thank you!
Helped a lot
Thanks! This helped me a lot!
Awesome!
THANK YOU SO MUCH MAN you have no idea how much you just helped me
Great job explaining this one
Thank you so much!!!!
thanks for the info. i'm super new and i brought a model in to here with 16m triangles from nomad sculpt and it took forever to load and then decimate the model. I appreciate your instruction!
Are you me? Lol
Thanks. Really clear and comprehensive.
Glad you enjoyed it!
amazing piece. Thanks
Thank you So much ... This is very helpful !
Glad it was helpful!
Thanks for i really needed this.
Thanks bro.
I had downloaded a terrain model for my game in python and it had so many faces even my rtx 2070 super couldn't handle it. This saved my life (and my computer)
today.
Awesome - glad I could help!
Wow thanks super simple
thank you man helps a lot :)
Very helpful, thanks so much!
Glad it was helpful!
great vid, thanks!
Thanks for the video, it really helped me.
Glad to hear it!
Best tutorial on RUclips
many thanks!
very informative, thanks.
thank you!
veery good video!! TXH!
very helpful, thank you :)
Very useful , thanks for sharing
Glad you liked it!
Thanks mate
Dude this was so helpful! Had a scenery with a terrain that had about 5 Million faces (I don't remember what happened LOL!) and I turned the Collapse ratio to 0.1, and now my .blend file is about 155 MB instead of 855 MB! And the terrain looks the same as it wasn't even touched! Thank you so much for this tutorial, I will use this if this (God forbid) happens again!😁👌
really helpful... crystal clear thank uu
Glad to hear that!
very useful, thank you!
Glad it was helpful!
BIG HELP 🥰
Thank you!!!
You're welcome!
Thank you bro
Thank you for showing the explanation of decimate.
I got a very high poly count character.
Pc working so slow. Will try this
Your tutorials have helped me immensely. I'm creating an entire new furniture replacer set for Skyrim.
Log Furniture! Because Nords you know
Nice thanks a lot !
I would have liked to see the wireframe on the "Bonnie" model when you did the different Decimations.
Thanks for using that model, btw.
I've been watching a lot of Blender tutorials lately, and the "Suzanne" Monkey face is getting pretty tired.

So I notice that when I go into edit mode to delete some things all the original vertices show up again. It makes me wonder. So all of the original geometry is still there, so what is really being accomplished with decimate? Does this mean the rendering will go much faster? As far as just working with the environment in the layout mode, I don't really see a difference in performance. I hope it does help in rendering time.
i was doing donut tutorial and sub divided icing too much , and it was crashing again and again but this video helped me , thank you .
Great tutorial...:)
Thank you!
muchas gracias!
Oh cool I need to reduce my 211MB STL to just under 100 MB but retain enough detail. I will explore the decimate feature. My artist made this guy and after smoothing it got up to 211 MB. Thankyou Thankyou!
thnxxxx so helpful
LIFE SAVER
appreciate u bro
Wow thank u very much this save me a lot of time. I am using blender to import models to a lighting software so with lower poligons it makes the calculation so much faster. Also I have a question is there a site where I can find simple 3d models already made, like chairs, tables, trees, display furniture for shops?
Sketchfab or Blenderkit
Thanks for posting this tutorial on the Decimate Modifier. I notice you joined all the objects before using the modifier. Is it possible to apply the modifier to different, unjoined meshes? For instance, a Decimate Mod for the horse's mane and a separate modifier for the robes, resulting in a reduced edge count for the densest part of the mesh.
Sure - they just get applied to the individual meshes as you add the modifier - not sure how they'd look when they run into each other
fuckin beautiful. Thank You.
Is there a decimate or auto retopo tool that will turn a geometry to quads with decimation applied?
You can select the faces in edit mode, Click faces tab at the top and click Triangles to Quads
Jesus thank you, my model had 661,350 something faces and it was suppose to animate, I was losing my mind lol
Lol - glad I could help
can i have the Decimate object in the Edit mode? I mean when i have a model with many tris and would like to reduce them with this modifier. Can I somehow bring the result into edit mode so that I can edit it further manually? Because if I go after the video and then switch to edit mode, in edit mode it has the original model (with the original amount of tris) and only in object mode does it have the reduced tris that I reduced with the Decimate modifier.
This guy intro is so funny
You will get small (black) triangles when you do this. This is due to the UV map which is also reduced, and blender do not know where to take the texture from. It is also good to have two (objects) of them an rebake the Texture from hi to low poly so you can get rid of the black triangles.
I didn't get small black triangles when I did this, so...
@@TheCGEssentials ??? Maybe it depends on the UV map? I tried this with a Meshroomscan.
I have a question however I am unsure what exactly to ask for when going on public forums, for example I have some models I've ripped from old games I used to play and wanted to do some non textured Blender art but the only way I can make the rips/meshes look really nice was to use the flat shade thing and now there's a bunch of individual flat faces/edges or whatever it's pronounced and I have no clue how to keep the overal amazing look but making the edges/faces flat/smooth it's weird I guess.
I didn't know statistics overlay was a thing. How did you get that option? I don't have it
I use decimate often when I bring in models from Adobe medium. It’s a massive struggle to retain what looks like simple geo for some mud brick looking houses I am making for some villages. But when I decimate. To get even simple looking meshes of homes down below 500k polys homes always start to look like melted butter. It like the trade of for voxel work is either work small or have a scene that looks like melted butter. I wish decimate kept hard edges
thank you! great video, i did the decimate on my sculpture, however, the size of the file does not change, any suggestions? im new to this. Thanks!
Well your file size wouldn't change unless you applied the modifier because an active modifier doesn't change the underlying geometry
@@TheCGEssentials Thank you so much for the reply, it worked!
Does the model loos quality if the detail were made when i subdivided the model?
Is there a way to decimate, but mask part of the mesh where you want to keep a little more detail?
You can split the mesh (not in practice, just so that the inspector considers them 2 meshes) and apply different modifiers. You can ask on r/blenderhelp if you want more info
Use vertex groups, theres an option in the decimate collapse to use a vertex group as mask.
you can also select the vertice/faces you want to decimate in edit mode, go to mesh > clean up > decimate to reduce the amount of polys only on the selected area
Do you need to apply the modifier to spped up the viewport performance? my observations are you don't need to, but I'm not sure
After I add decimate modifier and change the bar, nothing happens
Which node setup is Justin using to create the creepiest video intro ever yet the most interesting content on Blender? Separate XYZ? XD
very helpful video, but there is something you didn't going into that is killing me: I can only apply a Decimation to items within my collection that have the downward facing triangle icon next to the item, not the container (?) item with the 3-branch icon.
since I have over 3,000 item in the container, apply a decimate to each item in turn is not an option. Help?
First time to hear it! I am a beginner but I am trying to draw 3D characters and make them as NFT! Thank you very much for teaching us!
So, do we need to re-texture our model after reducing its poly or not?
No.
this was a life saver! im making my first vrchat model and it has a lot of performance issues like having NINETY THOUSAND POLYGONS instead of the recommended 20,000
theres other issues too but i will figure those out soon
On my spacecraft they having 26,386,264 polygons
👍
how do i combine mesh into one big mesh so it wount take to mutch of my pc power??
All of the experienced 3D animators on YT should start a discord . Where beginnings could ask questions and get some help
Isn't that why we have comments?
@@TheCGEssentials sometimes you can’t articulate your full question on specific things . Like a conversation in a discord VC
I use this to create LODs for game models.
