I want to create a crowd kite animation, the kite body is physX shape, the kite tail is cloth, how to bind those thing together?
Cloth and PhysX do not have 2-way interaction. However, the solution is simple...don't use cloth for the string, use a PhysX Bind setup instead, with binds set to 'tether' mode. It'll act just like cloth with the right settings, and be compatible with your PhysX kite.
