Hey all good, there is no issues, I just want you guys to check out my fork that including multiple things. Don't want to make a pull request yet since I feel like it still can be improved.

This fork switched to a library that I write to parse models CubeConverter which is also Open-Sourced and based off BlockBench.

There is multiple things that I implement which is the list right here.

• Added support for per-face uv map.
• Fix multiple exceptions on servers like Galaxite
• Fix arm/legs formatting being incorrect.
• Put part into root if parent not found.
• Support rotation in model parts. (Which can fix Zombie from 1st birthday pack doesn't have arms raised #2, haven't test)
• Proper support for slim skin.
• Added support for unique custom model (Car, Clock, .....)

There is multiple things that I fix like crashing on Hive, Galaxite, the formatting will not works if it lowercase leftarm instead of leftArm for example. Support for slim skins, since it seems like you guys don't have that. Also introduce perface uv map, since it seems like your parsing only support box uv. Rotation and others.
