I’m experiencing an issue where a .abc file I’ve created from Marvelous Designer crashes when importing into Unreal. This only occurs with the following steps:
- removal of keyframes from the animation timeline in Marvelous Designer
- the segment of the export contains the removed keyframes (but includes keyframes on either side of the removed keyframes)
The crash occurs even if the export is the entire animation. It does NOT occur if the export does not include the portion with the removed keyframes. It DOES occur if you manually add keyframes back in using the Marvelous Designer Animation timeline to Insert Keyframes to refill the gap.
When importing, Unreal throws a Exception 0xc0000094 encountered exception in FFrameRate::IsMultipleOf during the Controller.SetFrameRate() call as part of FAbcImporter::ImportAsSkeletalMesh.
Blender can import the Alembic file with no issues.
Has anyone experienced this issue and figured out a workaround? It’s a blocker for us, because we are trying to use this method to clean up looping our cloth animations, which are currently too janky at the ends of the loop due to the cloth animation not looping cleanly in the Marvelous Designer cloth physics without some intervention to clean things up.
Thanks in advance!
