Bake AO based on materials
There are lots of situations where some parts of the asset move, and it ends up exposing the AO that is underneath them (and it looks like an artifact). So, there should be a way to assign materials to the groups/geos that are static and then select to bake the AO separately based on each color group.
In that case, there should be an option on the Ambient Occlusion texture set > Self Occlusion > and then on dropdown menu, select "By material".
It's something hard to explain but I'm sure those who use SP on a daily basis production will understand my pain.
Thanks in advance
