Hello there, Marmoset toolbag is working on viewport with .alembic file and animation, everthing is okey. When i try to export animation viewer, on the Marmoset Viewer is not working. you can see only still frame. (I am using marmoset toolbag trial version.)
Currently Alembic geometry caching is not supported in Marmoset Viewer. If you have a rigged and animated mesh we recommend using FBX if you plan to export to Viewer.
