🧵 Help me with normal map baking?

Anonymous at Fri, 6 May 2022 18:30:12 UTC No. 895736

So I took the advices in >>895228 and bought substance for texture work.
But I'd still like to use my materials generated in blender for some objects that I already have texture maps for.

I made a hi poly version of this table, decimated it to an acceptable poly count limit, and tried baking normals in blender with selected to active along with a cage mesh.

But my normal maps come out really weird and stupid like in the post below. Can someone help with what's going wrong? I've used a cage mesh too.

Also when I apply this normal map to the texture my low poly table's triangulated faces sort of stand out as well in the lighting. What am I doing wrong?

I will for the other assets, I'd like to know how what the problem actually is.

Ok nvm I fixed the jagged normal map faces by selecting non color on the normal map texture.
I reduced the size of the cage mesh and flipped normals. I've got this map now. how can I improve it?

Nvm I got a decent normal map now that I've made the cage mesh even smaller for some reason?

Nvm I need help again how do i get rid of the black spots in the normal map? :(

He bought it.

why? it's cheap and apparently the best for texture work.

Rather than using a cage mesh, temporarily set a displace modifier on the target object and find the perfect value of normal extrusion to encapsulate the bake object. Use this value for your cage value. Discard the displace modifier and go ahead with the bake

how do I find the perfect value?

why do you even need to bake that? the high poly looks the same just more dense for no reason

Be aware this process might be painful to learn, everyone goes through it, so don't give up.

First of all, just bake normals in Substance, ignore Blender. Ignore shitty generated material in Blender, you can use materials from Substance, even those are probably looking better, but there's also plenty of free textures on the internet. Substance Source, Textures.com, Megascans etc.

Don't decimate this kind of a mesh, you'll get a bad quality low poly. Just delete every second edge loop from the table and it should be fine. You could then optimize that thin section on the bottom some more, but it will probably confuse you atm, so just ignore it, I assume you're not selling this anyway.

Bake depends on proper UV unwrap, so learn how to do it right, too.

Please go through some tutorials, I know you haven't because you wouldn't be doing what you're doing now.

Why did you get triggered by somebody spending a bit of money on some software? Yeah, he bought a program he doesn't know how to use yet, but so what, it's not like it's your money lol

OP how hard can it be to write **"How to bake from high poly to low poly"** in youtube or google... tell me pls i want to know...

Make sure your cage covers the whole thing properly, experiment a bit with ray distance.

>>895744
Instead of reducing the cage mesh and all that, just adjust ray distance like >>897057 says (it's below the 'selected to active' checkbox) and bake over and over again until the normal map looks decent.
