Mix texture and transparent image I've been asked to do a small animation for a multi story ice cream store. I want to have a steel background texture with a transparent image of an ice cream on just the front face of the elevator door. Most solutions I've read through mention unwrapping the face, but that gives me the following message: 
"Object has non-uniform scale, unwrap will operate on a non-scaled version of the mesh". The transparent image also applies itself to all faces of the door. 

 This is what I have. And this is what I want. How do I go about doing this?

Thanks in advance,

Joe
From what I understand, your unwrapping is the reason. You have unwrapped the faces so that they are overlapping. In the Image Editor, while unwrapping, try moving the faces so that they are not overlapping. Then when you add the transparent image make sure to tweak the Mapping node so that you offset it where it needs to be. 
I hope this helps.
