The first version of our FBX importer was added in Godot 3.2, and relied on the Open Asset Importer library (Assimp). A lot of work was done at that time directly in the upstream Assimp project to improve the FBX support, but we hit roadblocks with the compatibility with Maya’s FBX exports. Maya is one of the most used 3D assets creation tools in the game industry, and IMVU needed good support for its FBX files.
