Setting up a metallic foil overlay with transparency using materials and textures I'm trying to setup a label for a supplement bottle.
I want to have 2 materials, one that is the &quot;main label&quot; (.jpg image) and another that overlays that label with a metallic foil (which is a .png image with transparent knockouts around the metallic areas).
Attaching some screenshots of what I've been able to accomplish so far (screenshot 2 is just to show what the underlying &quot;main label&quot; should look like), but can't seem to get both the main label and the metallic overlay to show up at the same time. Here's some questions I have:

Should these be setup as 2 distinct materials, or should the main
label be the material and the foil overlay a texture?
I have read a bit about &quot;UV unwrapping,&quot; but felt it doesn't apply
here, is that what I'm missing?
In screenshot 1, you can see I have 2 image nodes - the one
connected is the foil overlay, which seems to be working with
transparency, but how can I add in the &quot;main label&quot; image underneath
that? Am I missing something there? Every time I add it in it
doesn't show up.


Metallic foil overlay

Underlying image needed
Another way you can do this is to combine the label text and the gold foil using a mix shader, and the alpha value of the foil image as a mix factor. I took the b&amp;w value from the foil and used it as a metallic factor as well. You can increase the &quot;metalness&quot; by dragging the slider on the right side.
