Unfortunately not as I have no idea what the issue causing it is in order to reproduce it.
The output log just repeats the same error about PhysX 3.4, but I can’t locate the directory it is giving.
LogPhysics:Error: PHYSX: (D:\Build++UE4+Release-4.14+PhysX_Compile\Sync\Engine\Source\ThirdParty\PhysX\PhysX_3.4\Source\PhysXCooking\src\Cooking.cpp 198) eINVALID_PARAMETER : Cooking::cookConvexMesh: user-provided convex mesh descriptor is invalid!
Thanks
