Im currently trying both methods.
The ones you posted on youtube.
Im also trying "The Agents" method of possessing a (Horse) pawn...
I thought the landwalker would work since my horse is a walker type.
Im worried that the horses feet will rotate like a car if I use the scorpion code lol.
should be no problems, please realise i can't test my tutorials on each UDK build but i'm willing to help you along via my support thread
