This is a really simple and small mod in the same vain as my invisible Braun mask mod. This one makes Joe Gacy's black sheep mask invisible.
Useful if you want to use his entrance for a different wrestler and don't want the mask to magically appear at the end. If you just want to make Gacy come to the ring without the mask, you'll still need to delete the mask on his model, as this only affects the mask prop used at the end of the entrance animation.
Simply drop the folder into your props folder and bake.
