Procedural Pixel Art Fire

Date of Recording: 2020-11-23

This week, I worked on a procedural fire effect. It is a typical game-engine procedural particle-based fire (no Navier-Stokes fluid sim) rendered to a buffer and then post-processed onto the viewport with a color quantization shader.

This method of rendering gives a pretty good balance between flame detail complexity and particle-system simplicity, allowing for this torch flame effect to run on only 100 active particles. Different parts of the fire (core, flames, embers) run at different frame rates to emulate a hand-animation look.

I think there are still improvements to be made in the look of the flames, but this seems ok for a first-pass attempt.

The lighting is absolutely stunning. The fire itself could use some tweaks though - natural fire isn't as red as shown here, more orange with brownish-red edges. The colors also stand out a lot because they are much more saturated than everything around them, making the fire look glued on like a sticker. If it was toned down a bit, it would fit into the scene much better.

Absolutely breathtaking...
the lighting is so professional I wish I had money to to fund this for the intro of an indiegame.

this is fire. I know absolutely nothing about GPU programming but I just started learning because I've been really inspired by these!

Beautiful, fine art to say the least.

I'd try having multiple light sources, to make the shadows below the fire less "jumpy"

It’s wild how much you can do just by scrolling perlin noise :D

Id lower the framerate of the fire to settle it better to the overall look

Hey how to create this effect? I mean to say, how to achieve the interactiong of the light with the surfaces? The way the light flickers and the shadows change along with the fire

dude plz make some tutorials when you finish your studies

Amazing fire and light interaction!! new sub
