Not that I know of. With both set to BlockAll, it should be true that they would understand that they both block each other’s sweeps.
That said, I realized something about the project: Raytracing is disabled deep in the settings. While I’m not quite sure that this is why I’m having issues, and turning it on crashes the program, it might be worth looking into. Is that raytracing enabler in any way related to the rays we’re using here?
