Included with this community fix is a .png of a new AO bake for the jag, .objs for lod0, l01, and lod2, the .blend file with all 3 objects, and the pre-compiled version of the jag with the fixes in place.

This submission is a community fix for the Jag and its weird lighting issues. All of the issues stem from the fact that none of the edges are marked as sharp, leading to the lighting attempting to wrap around the model as if it's circular/cylinderical.
All that's needed to be done to fix the issue with the model is to mark parts of the model with sharp edges, please look at the blend or .obj files as a reference, as the entire model was re-sharped.

Alongside this, a new AO bake needs to be made for War Paints, as the original AO bake has built in lighting issues due to the lack of sharp edges, and the tape is missing all definition as well.
