I have been using PhysX for cloth simulation. In v 2.8.4, we had NxCloth::attachVertexToGlobalPosition function that allowed us to change particle positions dynamically. I am looking for something similar for the latest PhysX v 3.3.1? I cannot find anything similar in the documentations. So my question is how do I go about changing my PxCloth particle positions dynamically? Lets say I want to change the positions of the pinned cloth vertices, how do I do that now?
