So, I have a sphere, which is transparent, and a soft body. It is dropping onto a plane and bouncing. I'm trying, then, to fill this soft body sphere with miniature rigid body spheres. These, ideally will bounce off each other, while being stuck inside the soft body and bouncing with it.
However, my tests so far, there is no interaction between the rigid bodies and the soft body.
NOTE: I have collision on both the rigid bodies and soft body.
