Alright, here's a question that may have a very swift answer in either one direction. When you fall from a certain height with an insufficient Force Jump, you take falling damage. Force Jump 4 (at least on our server) prevents fall damage, but still plays the falling sound as if you just crashed into the ground. Could you have a certain model overwrite it by adding a replacement sound to your .pk3 and scripting accordingly, or is it scripted into the server somehow? EDIT: I just realized there are two sounds in question, one is the model's grunt, the other is the supposed sound of the person hitting the floor. I'd be looking to get rid of both.
