I stopped trying, I wasn’t able to produce anything remotely usable back then.
I continued to use the standard rhino materials. The standard bump texture (grit or speckle) that I use to achieve a sandblasted or beadblasted metal texture is pretty limiting. If you want a fine grainy structure on a not so small surface, you will see the pattern repeating. That’s why I would like to revisit this topic now.
This post helped me to set it up and get simple results:
But I’m still far from getting anything like I want to achieve. Blender tutorials don’t help, at all. I hope someone could help.
Just getting the “noise” work so that I have an alternative for the rhino “grit” or “speckle” bump maps. For a start that would be great.
