how do i get rid of the surrounding stuff around the label? like how can i make it so its just the label overlaying the material under it? i know i didnt make the rest of the material yet.... i put that label there using the explanations niki gave me in the other general thread i made. i set a selection and then i applied the texture and used the texture axis tool to position it properly. what do i need to do to get rid off the surrounding bg?

if I've understood well ..you need to make an alpha map..make the same texture of the label in black and white, add it in the alpha channel then...
