Hello! I work in Maya and try to use Bullet.
I create Rigid Body from torus, then chose collider shape type = "mesh". In the solver I chose 'debug draw' in order to see everything. then I animate radius of torus, then I create softBody and drop it on torus. SoftBody interacts only with the invisible torus (of initial radius), but not with the animated one. The same problem I have with blendShape, skinCluster, nonLinear deformers. How can I calculate shape in each frame?
