I've created an animation of my dancing girl in Blender 2.83, and for getting the better performance of her breasts deformation, I've bound Lattice with her spine bone, and added a Soft Body physics on the Lattice. To make sure the Breast deforms as the Lattice does, I added a Bone Constraint tool named 'Track To' for the Breast Rigging Controller, which helped the Breast Rigging Controller keep pointing to the End of Lattice as 'Target' .
After all these, the breasts deformations do good in blender,
but they can’t be exported successfully in .abc file.
I’ve tried the ‘Calculate To Frame’ & ‘Update All To Frame’ options of Cache Setting, and it didn’t work.
I’ve also tried the ‘Object>Animation>Bake Action’ of Top Menu, that made no differences in .abc file.
Any help would be appreciated, thanks a lot.
