Adding optional blending mask directly from sbs or sbsar file
Currently in Alchemist, you have height map, curvature map, ambient occlusion map, and custom image as blending mask. Right now I have some filters that contains mask for layering in Alchemist. However, I can only save them into AO channel and then I can use the mask in Alchemist. It would be nice that Alchemist detects optional mask inside sbs or sbsar files.
