Hello,

I have a problem with the new ambient occlusion material mask feature. When I blend two Material Functions with the MatLayerBlend_Standard node using PrecomputedAOMask it seems that the normal channel is not affected at all.
On the forums I found a post which describes the same problem but with a simple lerp blend setup:
new Ambient Occlusion Material Mask do not work with final material Normal input.

Thanks in advance!
