#screenshotsaturday because I somehow forgot to ever show this:

Did some explosion VFX for @batterystaple_g 's 20XX earlier this year

The base effect all one shader on one quad, using a single texture containing noise+color info packed into channels; no particles or flipbook animation

Randomizing initial UVs shifts the shapes/motion around a bit, so if you spawn a ton of them you still get particle-like variation across individual bursts

The blue flash is also a single-quad procedural anim, but it has to be separate for blending purposes (uses the Blizzard "blend-add" premultiplied-alpha glow trick)
