This will give jerseys with wishbone collars, round collars, and v collars smaller arm holes and much less movement in the jersey. The great part about this is the shorts still move, so it is much better than putting player details on low. (No jerseys appear when player models on low.)
Please remember to back up your original files.
Also I have edited this with RED MC iff editor so it is not possible for anyone to edit the 3d models I have made. Please ask permission before attempting to include this in any mod packs, full conversion mods, or in addition to any globals.
I hope you all enjoy this. I have found that using these jerseys slightly helps FPS.
