I’m trying to get the correct surface sound, but using a motion detector on a ragdoll (an emitted non-controllable clone). Only gravel, grass, and default work. The problem isn’t the type value but the impact signal that I test to be nonzero is always coming out as zero for most of the surfaces. I have no idea why. Its frustrating not being able to replay frame by frame in test mode. Debugging is inordinately time consuming and annoying.
