Convert Normal Map to Geometry (for 3D printing or sculpting)
HTML-код
- Опубликовано: 25 янв 2021
- If you have a model that fakes detail using a Normal map, it can be interesting to convert it to ‘real’ geometry that you can continue sculpting on, or for use in 3D printing. This shows you how to do it!

When he said "your computer will Love you" ....😂😂😂😂😂😂
Yes! It will love you for 5 days! :D
"Your computer will love you"
WAAAAY TOO RELATABLE :D
He be buff though
Imagine doing push-ups with that body!
@@BlenderSecrets ye like 300 considering his weight

I'd like you to do a longer version of this, and slow it down, so I can understand it better. 🙏
T-rex be flexing! That really caught me off guard! XD
The bump node takes the derivative of height node along x and y. To convert into height, plug the map into the normal map node and add the integrals along x and y. The constant of integration does not matter as it can be changed inside the modifier. To integrate, multiple the value of normal map along any axis and multiply it with a small number. The small number is like the resolution, integrate through all axes and add. Using math nodes it can be done inside blender. Just bake the map after that by using the viewer note and baking omit map
I could never remember all that ;-) But thanks for adding, someone will find it useful for sure!
This is really interesting! Could you write out the equation?
I'd be really interested to see what you mean about integrating inside blender using math nodes - I can't quite understand how to do it from your comment.

The arms made my day! Thank you, on point tips!
When I tried it, it looks like it's just interpreting it as a height map, not converting the normal map, so it's prioritizing the Green/Y channel. You can tell in areas where the height should be flat, it instead seams to be sloped.
Have you perchance found a solution?
now that's a lizard who doesn't skip arm day
I licterally wrote Convert Normal Map to Geometry for blender, and I though I'm pretty sure blender secrets has the solutions... INDEED JAN has always the solution!!!!
GENIUS
51 seconds that tells me everything I need to know. Thanks!
Thank u for this short tutorial ,helped me a lot !
This is just what I was looking for!!! Thank you!
Loool XD That's very funny)))
Thank you you have just made my week with this
Amazing! Very useful! Thank you!
My computer froze for 2 years when applying the decimate modifier, but thanks, i can 3d print now
Funniest short tutorial clip I have watch in a while.. thanks for the giggle at 12 at night
"your computer will love you"
*adds buff hands anyways*
Thank you, this is very useful!
Thanks Warkarma!
I really hate it when good tutorials like this one are made by people who seem to be in a hurry.
so this is the method they used in Jurassic World to make a practical model of the dinosaurs from the cgi, thank you!
That website doesn't do what you think it does. Try Awesome Bump instead.
Life saver... thank you.
wonderful.
Or use materialize to convert into a height map
XD the arms
Thank you so much!!
Thank you.
Me gustaría que hiciera una versión más extendida de ésto, así lo puedo entender bien. 🙏
I'd like you to do a longer version of this, and slow it down, so I can understand it better. 🙏
OK. Who wants to download a bunch of fighting game animations and make the dinosaur uppercut people?
I can send if you want
Great! Little bit slow down please. :D Thanks a lot!
Haha most funny tutorial ,I like your humor sense
i need a pair of those
That’s awesome. Is there a more step by step instruction?
In my book it’s more “step by step”
Oh thank you. Trying to make a leather stamp for someone and print it
Ah, that’s a clever idea! So you’ll use it on clay?
New arms 10/10
HOLY MOLY
At first I thought "why the hell would I want this" then you mentioned 3d printing
But yeah, definitely the pc will love it
Hey, how to scale particles in one region of an object?
Fuck yeah
now i can see... its love.
what if I got 1 mesh but 2 different normal maps (2 materials)?
I love the arms!!! 😂🤣
How do you export the normal map?
The Dino back with thicker arm to fight the Godzilla and King Kong.
The website does not create a displacement map from a normal map, when I try it, it’s obvious that the generated displacement map is wrong. The website requires a height map input, not a normal map. As far as I know there is no easy way to convert a normal map to a displacement map. It requires specific software.
It's incredible how very few people over the comments noticed this.
@@fluxcapacitor yeah I even told Jan (Blender Secrets) and he said I must have done it wrong. 🙄
@@roofoofighter however, aren't bump (height) maps and displacement maps basically the same? If so, and if the web site really doesn't work well with normal maps as an input, what's it for in fact?
I dont know if that website works for Normal > Height. Seems its setup to work the opposite direction?
You are correct. This video needs to be updated.
I am trying to avoid tiling, any tips?
i mk love with my computer every 15 mins
I can't get this to work, NormalMap-Online seems to only takes Height maps as input, not normal maps
Is there also a way to convert ‘curve’ geometry to ‘real’ geometry? Thx for the tutorials!
Type F3 search for "convert to", then choose "to mesh".
Did you make that model?
why you cut out mouse clicks...
Pls make rocket fire trail tut
can someone explain why we need Decimate modifier??
It's often a good idea before 3D printing to use a Decimate modifier to lower the polycount, it's easier for the computer, smaller file size etc.
rex with seps .... end
Little hands on the Dino
How many vertices is the final result?
A lot! That's why I recommend using a Decimate modifier. I'd say I recommend that always with preparing a 3D print model. Then export as STL or OBJ file.
when i add a displacement modifier, it just inflates my mesh like a balloon
By default in Blender the Strength of the Displacement node is 10 x too high for some reason
oh god, I would have known about this a year ago. All this time I looked at a 3d model with a normal map and sculpted everything by hand 🤦♂️🤦♂️🤦♂️🤦♂️
Good practice!
Excellente DA 😂😂
So I'm trying this and whenever I add the displacement modifier, my entire model explodes into a mess of spikes and spheres and looks totally wrong. Not slightly messed up like the t-rex does, but it becomes huge and totally unrecognizable. Any idea what might be wrong? I think it might have something to do with the fact the mesh is like, 3 different parts in terms of how the textures are applied, but I don't know how to make the displacement map target one part or the other as opposed to the whole mesh.
It's a dragon with 3 normal maps-- one for the body, one for the wings, and one for its props. I made a displacement map out of the body's normal map, but it looks like the modifier is applying it to the entire combined mesh and not just the body...?
It sounds like the strength of the displacement is simply too high. I've found that it's usually way too strong by default and you always have to lower it drastically.
@@BlenderSecrets the website creates random artifacts in my displacement map. When I use the map generated by this website on my model in blender without the modifier it has random spikes. I can use nodes in blender to create a great displacement map, I just cant export it to use for the modifier.
I NEEDED THIS FOR MY JOB
Hope it was in time!
i need help, i have a model that has several normal maps, how would i go about that?
Does the model consist of several objects? I'd convert the objects separately from normal map to geometry as explained here first, then join them all together.
@@BlenderSecrets i figured it out, but i cannot make look good when i subdivide it just gets separated in a bunch of circles and when i apply the displace its even worse and makes it look like a spiky ball, i have to change the strength to 0.05 to make it look 'reasonable' but for some reason it also creates a gap between parts. i think the model i try to prepare is just not well made.

You computer will love you 💀💀
Add some thicker arms..
I didn't expect he-man arms lol
OH LOOK IS A DINOSAUR
I have a stupid question for which I clicked on 2 links and still didn't see the answer, how much does the full e-book cost? I'm assuming its expensive if you're concealing the price
Hi Paul, the book costs 35 €, it says so on the sales page.
@@BlenderSecrets I didnt even see that, I looked all over, sorry
This is perfect since displacements is gone in ue5 for now just make it all mesh then convert to nanite
hhhhhh yeaaaaaah my computer did love me after that hhhhhhh he even gave me his favorite thing the blue screen .... love it xD
Haha, that's how you know you're working hard!
@@BlenderSecrets Hhhhhhhh yeah , thanks to your fast and awesome Tutorial
haha thick arms
Yes ofcourse ill do that * cuz me and my computer already love eachother*
Talk about sarcasm
Thanks youtube for making this a short. I love having to watch the enitre video agian because I missed a step :)
It’s not me. RUclips converts them without the consent of the creators. I understand your complaint, but please direct it at RUclips: I’ve asked them many times to convert my videos back to normal. It’s frustrating…
@@BlenderSecrets oh sorry no this was a jab at youtube i just worded it poorly.
@@monkeydad47 Ah no worries, I misinterpreted.
This is a meme or what??? LOL... 😂😂😂
those arms 😂
Yo when you're working with software as needlessly convoluted as Blender, maybe slow down a bit.
Thicker arms indeed.
he goes way to fucking fast. i thought tutorials were to help people who dont know how to do it
I think he wants us to buy the book for the juicy parts.
Emerge Prosthetics wouldn’t doubt it. “Oh I’m too fast? Pay me money”
@@KayhoticGames We gotta make a living somehow. It's probably worth the price of admission.
@@emergeprosthetics5870 so you think its ok to make a "tutorial" thats hard for newbie blender users to follow, making them pay for it instead?
@@KayhoticGames It's understandable. RUclips does serve as a marketing platform. Do I wish it was more explicit and detailed? Sure. Especially since there's not a whole lot on displacement mapping for complex UV's like he's demonstrating. Perhaps our posts will encourage a full-on tutorial on the matter 🙏
Add some thicker arms instead ☠️☠️☠️
This method is wrong!
It doesn't create the correct displacement map!
so I'm not very pro with blender or modelling. can someone please explain to me how to do this? I have tried several times and some of the things he says to do in this video he doesn't even show where to find them.
Hey Matthew, which part is where you get stuck? It’s true that this is a more advanced subject, I think.
NOPE!👎
What do you mean?
