I was playing around with trying to make a cool flame effect yesterday using a single Unity shader. Results were neat. I posted a quick tutorial with all the shader code here: gabrielkoenig.com/ghosttime/shader-driven-flame-effect/ indieindiedevmakingGameDev
I was prototyping for Jettomero, yeah, but I think this particular experiment doesn't quite fit with my existing aesthetic so I'm abandoning it for now.
