Maya Model - Animated with Trax Clips - imported Joint Orientations wrong

Unity Engine
1

Hi there, I’ve been trying to import a model animated in Maya using Trax clips but Unity is doing something to all of the joint orientations which I can’t figure out. Currently using Maya 2014 SP2 and Unity 4.3.2f1.

This is an example joint, proper, in Maya:

This is the imported .MB file within Unity:

I have tried every combination of bake/resample/rotation option, it has no effect. If I build a model that has all Joint Orientations as (0,0,0) then it will animate correctly using Trax clips, but once I start using Joint Orientation settings it comes into Unity all wrong.

If I do not use Trax clips, just using a single animation in the base layer of the Maya scene, it imports fine with the Joint Orientations. I’ve also tried using the “FBX Multi Take” plugin and it has the same result. I can re-import the FBX file back into Maya and it is correct, but Unity breaks it. Currently I am considering doing a single animation per Maya scene file, but obviously that is a hack workaround, not a solution. Please help if you’re able, I’ve spent several days tackling this to no avail :frowning: Thanks!

Sort of an update: I can take the FBX created with “FBX MultiTake” and open it in MotionBuilder, save it, and then it seems to be fixed for importing into Unity. Pretty annoying workflow but at least my project can move forwards.
