Summary
Starting with a basic FLIP simulation which spins the fluid about the origin and injects turbulence into faster moving areas, we look at techniques to light, shade and render the particles like the recent Samsung s22 campaign.
Over the course of the stream a few different compositions, lighting setups and color treatments are explored as well as PostFX color correcting and grading.

To speed up render times when rendering particles like this, you can reduce the reflection trace depth.
