Hi at all,
I’m new to blender and also to blenderartists.org.
I’M trying to render some objects with anodised aluminium as material.
Long time I have a problem with structure at the surface and the material looks very “painted”.
With some research at other materials I get a very nice structure with a noise texture as bump-map.
I’m very satisfied with the result but there is one last problem I can’t solve:
At all planes parallel to XY-Plane there are a bad structure at the surface. I think this is the result of the noise-texture mapped with a vector-map. But if I adjust the vector map to avoid theese structure I lost the whole structure in the surface.
Here you can see the result with the structure I want and the structure wich is the problem:
This is the shader for the material:
If you wanna try at your own, here is a small project to reproduce the problem:
example.blend (5.94 MB)
Would be nice if anyone can help me to solve this problem.
