SylannhThanks a lot ! Actually I solved it like 5minutes after asking, just unchecked "move to origin" in maya export, no problem !
Now there's another thing : the move animation.
H5 units go from back to front while using the move animation, and I must artificially add this motion in 3DS or Maya. I played some time with the "motion path" and "motion trail" tools, but the unit still remains on its place...
I guess the answer isn't hard to find however
to be honest, without a video, and maybe a file, it's hard for me to understand the problem...
