Converting FBX Files to an Earlier Version of FBX

You can convert .fbx files created in MotionBuilder 2016 to an earlier version of .fbx file format by choosing from the main MotionBuilder menu Python Tools > FBX Export .

Python Tools menu

Saving MotionBuilder 2016 to FBX version 2014/2015 or FBX version 2013 ensures compatibility with Autodesk version 2013 to 2015 applications.

FBX Export

Important: You can only export FBX files of size less than 2 GB to the MotionBuilder 2013, 2014, or 2015 version.

FBX SDK 2016.0 is integrated in the MotionBuilder 2016 Beta release. It supports 64-bit file I/O to open larger FBX files. Due to the change from 32-bit to 64-bit file I/O support, you cannot save files using MotionBuilder 2016 in the earlier versions. File export to 2014 or 2015 versions are added under Python Tools > FBX Export, so that you can open files that are less than 2 GB in size in these earlier MotionBuilder versions.
