General workflow questions/ FAQ update

[insertmesh]

Right now because the PhysX and particle bind solvers are independent, there's no easy way to achieve 2-way interactions.

Ok, gotcha. Question is of course...why would I need this. Just figured out a simple way to do that:

1. Create grain sim event.
2. In the same flow, create birth shape event.
3. in the grain sims particle physics op uncheck "process only this event".
4. Boom. Two way interaction with grain and rigid body...
