Help!Animation Shaking!

We create a skeleton in 3dsmax, it started with root bone "bip 01"(attached to a

dummy point), and exported this skeleton with ofusion ce,there's a stand animation within

the skeleton files.Then we found that the role stand animaion shaked up and down slightly

which is not as expected.We guess that the precision of the float data exoported with

ofusion causes the problem,may be.So, how could solve this pro?Is there any thing wrong

with the animation made or exporting process?

you might want to disable the animation optimizer (it might be that the scale in which the animation is very narrow) , this will solve your issue
