Christopher Reeves did you try dbPhyDeleteRigidBody( ObjectId ).
unlike a DarkBasic coders, you do have a choice, and thats is to call physX code direct, by calling the delete actors or what ever it called Nvidia PhysX.
Yes there are few bug in Physx plugin but when it was being fixed the first time round there where only a few coders that had brought it, so very few to find the bugs and have them fixed.
Taken me three years just to work out how to use most commands and to find some workarounds.
And thanks for letting me know what happens when you use phy clear, now I know that it works but not selectively, cheers.
Dark Physics makes any hot drink go cold.
