xiNavmeshOBJs

This repo is a collection of the intermediate output from FFXI-NavMesh-Builder.

The OBJ files generated by the builder can be culled and improved by hand, making them faster and less errorprone.

Since GitHub's git LFS offering has stringent bandwidth caps the OBJ files must be 7zip'd before they're checked-in using compress.py/decompress.py.

• Full compress time: ~800s
• Full decompress time: ~16s
