I have a friend who has what is called "Fragmotion." He has used this to turn some of his own models in the right direction. I sent the Pitcrawler and Spiders to him and he'll see if he can fix it. If he can then maybe he can fix the models you want to use as well.
So, from one ol' grey matter to another . . .
If only I could get one more synapse to spark then I might be able to finish my game.
THEORY - you know everything but nothing works. PRACTICE - when everything works but don't know why. For me, theory and practice are combined: nothing works and I don't know why.
