Making a glow effect

I am working a small project and have been trying to add a glow effect to part of it. I found a locked topic (here: Additive Blending feature - #4 by dacap) but have no idea how they got it to work.

Thanks to anyone who can help


Also interested in some quick and dirty tutorial on this with Aseprite.

A tutorial on this would be great :smiley:

I’ve recorded a little video about how to make a glow effect (not pixel art oriented)

The Addition blending mode is not necessary, you can create a glow effect with a normal blending mode anyway.


That was interesting. I had not thought to use curves in that way.

This is analogous to parallel processing in the audio world… where you add an effect on a duplicate track and blend it in with the original.
