FBX -no animation data in unity. 100% ok when brought back into maya.

Hi,
We have a ton of characters and animations in our game. With one new character we can't get unity to see the FBX animation data and have no idea why.

-Everytime we import the fbx or change a meta file setting unity crashes with an Access Violation Error.
-After rebooting the animation says no animation data.
-after exporting many times we have had the animation data be recognized but no bone rotation in the preview.

-Reimporting the FBX back into maya the animation plays as expected.

We have tried legacy, generic, creating an avatar from itself, from the setup file, etc... no luck.

 

Does this happen in a new Unity project? Or only happen in your existing project?

 

We found a solution. (no idea why). Duped the file, renamed it everything is fine. Seams something metafile related?

 

note that using the "re-import" feature in unity, doesn't necessarily start the import process from the start, it keeps some data from the original import - its kinda lazy like that. Same thing when assets are "re-imported" after being changed. So for a real "re-import" it needs to be deleted and brought back, or do what you did with a new file.

 

This issue is back and this time we have not been able to fix it. We deleted libraries and reloaded still now luck. Any idea what could be causing this? Its odd that the fbx animations are 100% fine when taken back into maya.

 

I just had an issue that may be related - a unity project that would not allow import of fbx models in anything other than Legacy rig format. It looked like the animation was gone but obviously it's still there. Re-importing into a new project works fine. Haven't found a fix other than rebuild the whole project.
