I'm interested in sharing my texturing techniques with the budding lighting and texturing artists.
Create a lambert shader and call it label. Create a new file texture node from the 2D textures category and connect the file texture to the lambert’s color attribute. Next connect the file texture’s out transparency to the transparency attribute of the lambert. In the file texture node color balance section set the alpha gain to 2. Now that both our materials are ready, we’ll layer them to finish the material. Drag a layered shader in to the workspace. Now drag and drop the glass material created earlier into the layered shader palette. Next, drag the label material into the layered shader palette.
