Character Walk on a Wall? (E.g Sonic running around a loop)

So temporarily, I’ve used the Matinee way; Seeing SonicGDK (UDK game), I know that the psyhics I’m after is possible; But I’ve ripped apart Kismet and all the UnrealScript files and I can’t find their trick; So for now, this is how it looks (I’ll implement moving the player while the matinee is playing and launching him off the loop in a bit). It’s a shame that the running around the loop doesn’t seem to work from all the help you guys have given me; but thanks all for the help.

If anyone else has any suggestions, please don’t be afraid to say so! I need all the help I can get!
