In this way, I get one Material with a Layer for the ground-texture and another for the logo, is that right? But thats not what I want. I want to use different materials, so I can move the logo on different parts of the objekt.
Have a look on the objekt, I´m working with: (I send you a picture per mail, hope it works, because I´m not able to post a link.)
There is a metalic button with a red line On the original you can see, there are some symbols on it. I jolted the metal-material to get the actual look. And now I need a new texture for symbols to lay it over the metal, but i won´t work. I don´t now what´s wrong.
Generally I think its more comfortable if you can overlay different materials.
