2.3.3What version of UCC are you using? I believe this was a bug that was reported a while ago and may have been fixed in an update at some point - but I'd need to double check with Justin.
Okay. Some of my footsteps volume are lower and some higher as they are. That's why I can't really just lower the general foot AudioSource.The volume should be specified on the foot AudioSource rather than the SurfaceEffect. We've reworked the AudioManager in version 2.4 and am still trying to determine if this is still the best route.
