3ds max viewport canvas

i know this is a 3ds max question and not a unity question but i dont know any sites like this for 3ds max. i have made a person and now i want to put a texture on him except when i use viewport canvas to paint it paints in more than one place eg. when i paint on his torso it also paints on his legs, i have mirroring off and i tried uvw unwrap and it didn't fix anything. i already spent 3 hours google/youtube searching and found nothing, so dont tell me to do that. also i am using 3ds max 2013
