I wanted to change walking zombie.I exported tanim(bo1 ai animation) from  maya to cod.but when animation is running the half of the zombie  go to the under ground.so the animation is ok.the only problem is about position of zombie.anyone can help me please?
my anim file is:  ai_zombie_electrician_run_v2

This will happen with all bo1 and bo2 ai anims. You best bet it to use the graph editor and shift the entire animate up so that the feet are at a height of 0 in maya.

Thanks jbird632 for replying.try it later

thanks again jbird .the problem fixed. +1

youll often get problems with their knees and stuff too, and if you look at the joints in the graph editor you can see its clearly all over the place

usually deleteing just one of the odd keys snaps it back into shape

and player anims you need to fix the face, and often the elbows too
