Try this out and let me know if it's what you're looking for: WR_Mottle_Speed = 5000 (adjust as you feel like). To have uberfast movement, set it to like 100. (I hope I didn't reverse those two values.. I just got back from a meet and a subsequent victory feast, and now I'm dead tired).
In regards to CameraHyperJumpPitch = 0 , is there any way that I can get the camera to stay behind me but a little above me as well when I hyperjump? I like being behind me, but I would like to see the ground and where I'm hyperjumping to as well and not just the back of my coat.
