Cosmetic items can be either deformable skinned cosmetics or strictly static meshes with no deformation. The bulk of items currently released are static and this is preferable. Skinned items should only be used when deformation is necessary. Ana's scarf is a good example of an item that needs deformation. Skinned items must be skinned using the downloadable character source rigs as the skeleton.
Your weapon skin is limited to 1 32bit 2048 TGA applied as either a custom paint map or a pattern mask. You may replace the paint area mask if desired but this is only for advanced users. Modifying the base weapon textures is not permitted.
You are also required to bake all first person weapon skin textures to the third person weapon UVs at 1024 x 1024.
