Hey sorry George, I didn’t realize that 4.7.2 doesn’t have the fixes that you need. They are actually going to be included in 4.8. It’s the PhysX 3.3.3 update.
If you are using the Source version of the editor, please feel free to test your project in the latest Promoted branch on Github.
I was hoping to test this for you but everything that is stripped out of the test project causes it to not convert/compile correctly.
