I have an object with two non intersecting UV Maps. One UV Map (round.red.light.decal) is to place a red light decal (round.red.light.png). The other UV Map (rust.map) was used to draw an image mask (cabin.rust.mask.png).
I have my nodes as such...
But I have some phantom rust that I did not draw in my mask. The face the red light is on isn't even in the rust UV map.
Thanks for any insight. Here is my blend file https://drive.google.com/open?id=0B8ZnFrE6fxi_ZDNIanAyQ001RlE
