Export Animation Problem (3D Max to Unity)

When I export the animation from 3DMAx to Unity, the leg(foot) orientation of the bone is wrong (on the contrary). Only the left leg(O.o)

If I animate without rotation of the legs, the animation plays correctly. but if I adjust the foots, animation is wrong again.

I’m using biped animation without footsteps from 3DMax, and exporting as FBX Baked.

I try export with older versions of FBX Exporter but I don’t have success.

I try Export from Maya too. No success.

Someone can help me?

Try collapsing any animation layers or under the motions tab try collapsing the trajectories

The options for Collapse transform are currently disabled … and don’t use animation layer =/
