Hi, hope i have the right subforum for this question. I made a mesh object, with a custom (simple) physics shape that i uploaded simultaneously (load from file). Inworld i set the shape to physics properties "prim" and the rest of the build to none. This works fine, and its all walkable. After putting a vehicle script in (BWind) i noticed something strange, on the final state change, when shutting down the engine, my physics shape changes to convex hull instead of prim, trying to force it to go to prim state by script results in an error, but simply rightclick and edit somehow forces an update and the shape changes back to prim again. anybody knows what i'm doing wrong here?
