Particle Debris
If you checked ON in the Particles in Debris group, RayFire will create a PArray and an emitter plane at each impact point and animate PArray`s rate property. RayFire will also create a Gravity force and bind this force to the PArray. The gravity force will be called RF_Gravity_Debris. Later you can change its properties to get different dynamics for particles. RayFire will not create this force again at the next simulation if it already exists in scene. It will bind the already existing force to the new PArray`s. In case you did not define Debris references, debris will appear as a sphere with the impact object material.

Rate : Total amount of particles for each PArray.
Divergence : Particle divergence angle.
Size : Debris size.
Speed : Particle speed.
Life : Particle life.
Gravity : Gravity for particles.
Display as mesh : Displays debris particles as a mesh.
