EPhysXFilterDataFlags

enum EPhysXFilterDataFlags

Set of flags stored in the PhysX FilterData

When this flag is saved in CreateShapeFilterData or CreateQueryFilterData, we only use 23 bits If you plan to use more than 23 bits, you'll also need to change the format of ShapeFilterData,QueryFilterData Make sure you also change preFilter/SimFilterShader where it's used
