I’m not new to compositing, but I am new to Blender’s compositor. I was doing a tutorial, and reached a point where I had to put one element over another using the Apha Over node. Then oddly enough, I was told to put the above element under the bottom element in the Alpha Over node.
Immediately, this seemed counter intuitive. Why would my compositing tool visually want me to put something that’s going over… under? I’m sure there’s a mathematical reason for it, but again… to me… when you put something on top… it should go on top. A user shouldn’t have to do mental gymnastics around the software just to get a job done.
In the very least, can someone help set me straight by explaining the logic behind this work flow?
