Destructible Mesh Error

I have a simple wall mesh which I’m trying to create a destructible mesh for. Other meshes work fine for me, but this one produces this error:

LogPhysics:Error: PHYSX: (…\PhysXCooking\src\Cooking.cpp 217) eINVALID_PARAMETER : Cooking::cookConvexMesh: user-provided convex mesh descriptor is invalid!

I’ve tried redoing the collision all different ways, but nothing seems to help. Ideas appreciated.

Turns out meshes which are planes and don’t have any volume aren’t supported. Adding a tiny amount of volume in Blender enables it to work with the destructible mesh functions.
