I posted this in the general discussion thread mistakenly, so sorry for the double post if you see this again.
Bump maps don't seem to work with procedural noise when nested in texture rollout via the "layer" mode. They work in all other instances like Diffuse, Reflection, etc.--it also works as expected with images. Anyway, hope this can be addressed since it's nice workflow to utilize and I used it frequently in the betas. I can post a scene if none of this can be reproduced on your end.
Thanks!
