Trying to make a brush kick up debris

[rotanadan]

So here is an image of what I am trying to do. So far the particles will object bind to the spinning brush, but won’t “unbind” or spawn a new particle when hitting the deflector at the top of the brush. Any ideas on how I could do this?

Hmm... indeed.

I created now quickly that scenario, and indeed, the collision operator didn't worked after the object bind.
Maybe it's a bug, or it is meant to be, and it have some logic, that I don't understand.

However, I've used Surface test, and it worked.
Attaching you file.

Hope it helps.

This is perfect! thanks! Now I just have to make the particles pieces of trash that collide and pile up using PhysX but I should be able to handle that
