Blendshape and Rogidbody

[genode050470]

Hi there,

Can a rigid body be made of an object with blendshapes, where the blended shape updates the original rigid body, so that if, say, the blendshape popped a deformation underneath it, it would pop the rigid body up away from a collision plane?

I have tried baking the geometry into a cache, and this does not work.

Any suggestions greatly received

Thanks

No, by definition of things rigid body dynamics deals with objects that don't change shape*. If you want to do this then its soft body dynamics.

So you could try to do this with soft bodies even so it a a bit problematic on the whole as the points themselves would need to have forces and you would need to convert the movements into some kind of force for it to be useful for the dynamics engine. You could also convert the problem to many small rigid bodies.

• this definition applies to how the engine works it is quite unable to do things that lie outside of the abstraction that was defined to be the scope.
