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.

  • 00:00:00 Introduction
  • 00:01:35 simulation overview
  • 00:08:40 bringing simulation cache in
  • 00:09:42 viewport settings for particles
  • 00:16:05 particle density visualized as color
  • 00:27:50 setting up cameras
  • 00:30:13 adding redshift parms for particle rendering
  • 00:31:50 preview rendering
  • 00:33:30 crop particles to camera frustum
  • 00:43:07 adding rect lights
  • 00:52:10 making particle shader
  • 01:15:25 starting another color and composition
  • 01:36:00 starting another color and composition
  • 02:04:00 wrapping up


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