OnParticleCollision is broken

Hi !

I have a little sphere hit by some particles, but the OnParticleCollision function doesn’t work even with the simplest instruction such as “Lower the ball energy when a particle hit it”.

The ball has a default Rigid Body and Collider on it, so it is ready to sacrifice and get hit by the particles.
The particles have the Collision on, so they are redy to hit any collider merciless !

Is OnParticleCollision broken or am I ?

Thank you

Nevermind…I have found the fix !!
