Extracts/Transfers Metahuman Facial from exported FBX onto Maya face control board

Metahuman Facial Transfer

Maya Python code that will reference in previously exported FBX animation from Unreal. The code will copy these attribute keys from the referenced transform node over to the Metahuman Face board controls. The referenced file is then removed once completed.

Note: This was built and tested using Maya 2022.4 and 2022.5 running Python 3.7 using latest assets from Unreal 5.2.

The FBX data coming from Unreal 5 is incompatible with Maya 2023.

To confirm the animation data will work with your version of Maya and Maya FBX importer version (2020.2), open up the sample FBX provided in the project and if you see keyframe data exists on the transforms attributes. If not, then your version/cut of Maya is not supported with this code at this time.
