Composite glare overlayed by alpha transparency of other material? I know the discription is a bit weird, but hear me out: Look at the image. I put a glare filter on the 2 red eyes, but it doesn't shine through the part of the shiny triangle that's supposed to be transparent. How can I fix this? I hope I explained myself well enough xD[
Solution 1:

You might want to switch the blending mode from 'add to 'screen'



Solution 2:

Instread of a mix node you can use an 'alpha over'. to my experience this works better for more complex overlays with multiple colours. make sure you add the alpha channel to the 'alpha over' node or it won't work
(in your case you would take the alpha from one of the 'ID masks', not the alpha from the image)
