I don't know how to edit meshes, so I tried opening the texture file in Photoshop, and applying an alpha layer over the pants parts to hide it, but the problem was that the characters legs where cutout at the top, so I guess the meshes itself needs to be edited
If anyone can do it for me, I'll be thankful!
