Reviving this discussion. The latest FBX Python Bindings from the official Autodesk site now includes source to compile a different version of the fbx.pyd file.

(it actually links to a 2020.0.1 version if you decide to download the file.)
I installed Python 3.7 and used their recommended SIP 4.19.3 version and was able to successfully generate a valid fbx.pyd. Unfortunately, my tests do fail in some cases that do not using the 2.7/3.3 premade versions. Specifically, the search for binding tables (matching objects to shaders) appears to work, but I’m unable to pull entries successfully to introspect the shader attributes anymore. The GetEntry() func just fails.
Was wondering if there was anyone else looking into updating this autodesk module or is even interested ?
