1) Real time physics is possible, the question is what is the scale, and how detailed are the models.If you use a newer PMXE, you may try to call for TransformView window (F9), make sure rigid bodies are visible ("Bdy" button the upper left. Without seeing your model, I can't guess which ones they should be, though. "Body A" and "Body B" refer to a pair of rigid bodies (aka "physics") that the joint is supposed to connect.Rigid Body Animation Nodes and Cloth Physics.
The system includes the following major features: Rigid Body Dynamics.
Prototype of a first person puzzle game where you have to switch between classical and quantum mechanic to solve puzzles. Raising this can help prevent the soft body tunnel through objects in some cases. It's the minimum collision distance that the soft body will keep from other physics objects. SoftBodyParticleRadius - This is the equivalent to the cloth's "thickness". Setting both values very low will make the soft body lose its original shape almost entirely.
