HAH! ok I figured it out. By changing the units model size via triggers to -100% I was able to make the unit stand upside down. However, he runs backwards (lol) any suggestions?
(Heres a copy of the trigger I made)
Rotate
Events
Player - Player 1 (Red) types a chat message containing rotate as An exact match
Conditions
Actions
Animation - Change Gryphon Rider 0002 <gen>'s size to ((0.00 - 100.00)%, (0.00 - 100.00)%, (0.00 - 100.00)%) of its original size
(I had to use 0-100 because world editor wont let you imput a negetive integer in this trigger (even with it allowed under preferences))
