I’ll drop some stuff here. Feel free to comment, criticize, ask, or whatever you want.
Just tried around a little bit with a 2D-LUT and an Explosion Flipbook generated by "Effect Texture Maker" Website
The LUT (Look Up Table) is 2D so that can color-map the gray scale explosion texture (left to right) and also change the color over time. This stuff is detailed described here: https://simonschreibt.de/gat/fallout-4-the-mushroom-case/
I spawn 10 particles with the flipbook (64 frames) with different sizes, rotation and lifetimes.
