I don't know if this is the place to ask Joe, but does TB3 import without problems 16 and 32 bit PNGs, TGAs and TIFFs? I always get confused which importer was/is broken in TB2.
The Featurcsmallfield said: The Features tab on the product page has most of that information: https://www.marmoset.co/toolbag/ Alembic Cache files are supported. Particle cache is not. The baker can bake 32 bit PSD files. If there is anything else you would like to know, let me know.
