physX switch question

[rookyspooky]

If you disable all your group operators, they don't interact?

So I disabled all group operators, in event 05 I checked "only collide with" , marked group "2" ( which is strange because the groups are disabled?) Then I get a result like the second image in the first post. And then I cant set those green chucks to "dynamic" because everything gets collision and breaks apart.

   

If I uncheck "only collide with" in event 05 , everything collides with each other and breaks apart.

All in all I am trying to get a simple "rayFX" effect, the main goal is to have streams of particles carve a path ( or multiple ) in an object. I think its possible

Thanks!
