Hi, Trying to do a Vellum cloth sim. I've imported it as an FBX from Marvelous Designer, cleaned and separated the tunic and pants and draped the vellum on the character in rest position. Skeleton Deform for animation. About 40 frames into the simulation I'm seeing this left sleeve separate at the wrist and continues to the elbow. At 50 frames in, the collisions are messed up all the way to the shoulder. Currently substeps are at 4. I've experimented with constraint iterations, collision passes, and cloth stiffness in bends with no luck. Need help fixing this!!!

Thanks

it's my experience, that sometimes you need to increase global substep to better detect collision objects.
another thing is what type your collision object (the character) is if that is imported. (( alembic, USD))
because it needs to increase its substep from the source that it was animated.
