DISCLAIMER: This question might be nonexistent, it could just me not noticing the use of flipbooks, and I think that the graphics in AO are already amazing. Also, I would post under the suggestions category, but I don’t have a large enough trust level.
While playing AO, I noticed that pretty much every particle effect does not use spritesheets.
In case you don’t know what spritesheets are, they are collections of images that allow a particle/sprite (such as a lightning bolt from lightning, or a gas particle from poison) to be animated, so each particle is like a little gif. They can look amazing when used right, and so im just wondering why they are not.
In case you didn’t understand my bad explanation of using spritesheets, here is a (hopefully) better comparison. Fire magic, and similar magics, are visually made up of particle effects. Currently, each particle is “static”. The image does not change, instead vetex just edits the particle settings to make it grow, shrink, or change in color. Spritesheets, however, would allow for these particles to be animated. Each image used in the particle would warp and twist depending on how vetex animated it, similar to real fire.
Two videos showcasing the use of flipbooks/spritesheets:

2. I Made 40+ Particle Flipbooks So You Don’t Have To [ROBLOX] - YouTube
Once again, this could just be me being blind. There may be spritesheets used, and I possibly just didnt notice.
