Collition events PP?

HI Forum,

I want a particleobject to collide with geometry, but just pass right through. Is the right procedure for this to set resilliance to -1?

Please comfirm

Also, is it possible to read if individual events (collition 1,2,3 and so forth) for individual particles (PP) has occured?

If so, how?

Best regards, T.
