This is my setup, I have a plane that I wanted to display 2 textures. The first texture I want to show only part of it. In this example, it is the circular ring. For the second texture, I also wanted to show only a portion of it, this is represented by the blue circle on my example.
What I wanted to do is to crop out the textures, i.e. the ring and the circle, but not actually make the object transparent. In my example, I should still see the rest of the object which is a plane. Anyone knows a better way to do this?
Here's the blend file I used as reference:
