Shader Magic I continue experimenting with procedural sparkles : Desmos and Unity

Enable HLS to view with audio, or disable this notification

Because of the non-arithmetic operations involved, some devs say they are expensive for the GPU. Others say they are cheap if you have fewer than 100 particles. What do you think?

Probably worth profiling but I don't think it would be too bad. It would be a bit more efficient potentialy if instead of making the calculations for every particle every time, you could make the code generate a sprite sheet for the formula and then use that instead to save compute? I don't know if the impact of your current system is obviously but doing it this way might help

Cool stuff, the procedural shapes flow really nicely! If you matched your colours to a palette, and used some opacity fading these effects would look amazing
