I know that you are aware of this issue, but I want to bring this up again.
C4D noise is still not working correctly if you set it to world space and place it inside a layer or fusion shader.
I think the strength of noise is its world space mode. But you can't combine them because this issue remains unsolved.
So only one noise or everything in UV space. It's a huge handicap when you are creating more complex shaders.
This is a bit frustrating to be honest, and I hope you can give some love into this. I understand that fixing such things isn't easy, but nevertheless I would describe this as a basic feature which should be supported.
I really hope to get full support for noise and layer.
Thanks!
