Import of a take from the Motion Library to Autodesk MotionBuilder - fail

 Hi,

I tried to import a FBX generated by the motion library to MotionBuilder 2020 and there is something completely wrong.

First, MoBu throws a dialogbox upon drop of the FBX onto its window stating that this file was created by a student version of MoBu, and is illegal for any educational or commercial use.

Second, the take is empty. There is a skeleton in Tpose, however it lacks any animation data at all.

Please advise,
Stepan
