Short description of error
I'm trying to bake bevel to normal map and faced a problem. When you bake bevels in a blender, they look completely broken. I did some tests and compared them with 3ds max. As a result, I found out that blender exaggerates normal map contrast by about 2.5 times which breaks the chamfers on cube.
Next, I made a cube with very large chamfers to compare how the 2 algorithms behave.
Normal map baked by 3ds max:
This looks pretty good.
Normal map baked by blender:
Naturally i installed Non Color value. Problem is with the recording when baking. Blender Normal map looks grossly exaggerated,
and as you might have noticed, he cut off the corners of the cube.
I am attaching 2 normal maps that I got.
Normal map texture baked by 3ds max:
Normal map texture baked by blender:
I also tried to increase the contrast of the texture in Photoshop, and noticed that the Blender creates parasitic gradients on flat surfaces.
Exact steps for others to reproduce the error
- Make cube mesh.
- Make bevel cube mesh.
- Select Cycles
- Set bake settings -> Normal, Tangent, +X+Y+Z, Select to active
- Select meshes and create material with image texture.
- Bake
