[HELP] Adding vehicles to DOOM V3

[dNi3L]

Can someone help me figure this out? I added the Aftermath police car and ambulance and when I try to spawn them in I get this error...!!! ERROR: PhysX Error (internal error): 'ConvexHullBuilder: convex hull has more than 255 polygons!' at file ..\..\PhysXCooking\src\ConvexHullBuilder.cpp, line 1285..I've used both Physx 3.2.4.1 and 3.2.5.1 and rebuilt each time I swapped em,and I can't seem to even find anything related to ConvexHullBuilder in my external Physx folder..It only happens with these two vehicles..Can someone point me where to look to fix this? I appreciate any and all help!!

The vehicles from aftermath probably use convexes as collision. Go into the Physics editor and change the type to mesh and re-cook the mesh.
