Subsurface Scattering quick tips

  • Use fast or fast simple for things like fruits, candles, glaciers etc.
  • Use fast skin for human skin or the sort.
  • The fast shaders are all dependent on a light map, which means we have to set up our lights properly in the scene, otherwise scattering won’t work.
  • Use physical for juice etc.
  • Physical is dependent on caustic photons so make sure we emit them from the lights and enable it in the render settings.
  • Physical also requires real world scale, so we need to have our objects to scale.
  • The general workflow is to tweak each scatter attribute individually, isolating their effects each time.
  • Work with low sample settings until the final render.
