Velocity and EmitterTime from particle collision report random values
If you add a particle emitter, and add an Event Generator - Collision and Actor Collision
Binding an event to that Particle Emitter "OnParticleCollide" will report very random values for Emitter Time, somtimes rising values with each collision, and sometimes falling values.
Velocity will report 0,0,0 always, until the max number of collisions has been reached.
Let me know if this needs a repro project, and i'll set it up for you.
