Why not do a scan with BIG cone and set a indicator. In the event function you could remove the newton collision objects like this:

dll_handle=newtonHandle;
NewtonRemoveEntity(me);

Since you are working with newton, you can probably help me in return. I have problems creating hinges. They rest visible. I have a small test level and a project level. Both with the same script set and i use no templates.

Help would be nice!
