Enable/disable two way collision of particles with the rigid body scene. In either case, particles are influenced by colliding rigid bodies. If eCOLLISION_TWOWAY is not set, rigid bodies are not influenced by colliding particles. Use particleMass to control the strength of the feedback force on rigid bodies.

Enable/disable collision of particles with dynamic actors. The flag can be turned off as a hint to the sdk to save memory space and execution time. In principle any collisions can be turned off using filters but without or reduced memory and performance benefits.
