Transparent image over texture in faces I have a problem about adding an image with transparent background over the already existing material in a group of faces (or a single face) of an object. I saw similar questions in the forum but none of those gave me the result that I am looking for.
As example, I have cube which has been unwrapped, and has a material with normal map, mapping, etc

Then I want to add and image with transparent background on only one of the faces to get something like this (fake image using gimp)

I tried several approaches (multiple uv mapping, using mix nodes, etc) without getting the desired result. I cannot properly combine the two images to get what I want.  Which would be the best approach to get this done?
Thanks in advance

MixRGB node should do it for you. Connect the alpha from the image with transparency and use it as a mix factor.
