No, this is not about the long-standing issue that C4D noises need an insane amount of strength to render even subtly.
It's not even about noise in a layer shader is rendered only when it is in UV mode (although this is annoying, too).

Look at the image (scene attached).
All three cubes have one thing in common: They all have the same noise shader in the bump channel, at 100% strength.
The left cube has this noise shader (set to 2d space) in a layer shader. It's there, it renders. Yay!
The middle cube has the same shader (set to 2d space) directly in the bump channel texture slot. Renders as smooth as a baby's posterior.
Let's give the layer shader another try then. The right cube is set up like the left one, except that the noise in the layer shade ris set to the texture space). As if nothing had ever happened!

Cranking up the bump strength to 10000% finally shows some effect for the middle cube. But as I wrote in the first sentence, it's not about ... ok.
But even with 10000% bump strength, the noise in texture space does not show ión the right cube. Stubborn guy.

In short, it is pretty annoying to remember all the rules and exceptions WHEN a noise condecends to work as one would expect it, it takes up too much time!
Please, fix this!
