I am currently trying to texture a soda cup, but have some issues with the UV mapping I think, because the alpha image that I add on the cup is also visible on the inside of the cylinder. What I want is that it is only visible on the outside of the object. I modelled the cup only with a cylinder object.
Material details I've added the texture using nodes and a RGBMixer to get the transparent image. As you can see, the image is also visible inside the cup.
I tried searching for it on the internet, but didn't find anything related. Hope some can help me out!
