Hello

With Collisions being very processor heavy I am looking for some advice on best practices.

- Paint weights to limit calculation to certain zones
- Collisions on all layers seems like overkill, should it be done on the Muscle, MuscleGlue, Fascia, Fat, Skin layers or a combination of multiple layers?
- Should we/can we leave an offset to create a gap for cloth sims (such as between the upr arm and torso)?
- Etc…

Thanks

Cathal
