I’m having trouble finding a blend mode to show particles on top of a transparent background, particularly when that transparency is on top of a white page. The only solution I’ve found is to disable alpha blending, use a custom shader and manually discard at an alpha cutoff. This obviously doesn’t get you a translucent particle but at least it’s not square. Anything else is only visible against darker elements inside the scene itself.
Is there a Blend Mode that would work better? I’ve tried all the ones in the constants file and nothing is satisfactory. It doesn’t seem you can change the blend equation itself. I don’t need particles adding to each other, just a partially transparent particle showing against the white background.
