Particles Part 09 - Rain Part 01 - Setup (Patreon)

This time we'll create an often used effect, a wet road with rain pouring down. While particles are the meat of the effect it really starts to shine by using a wetmap for shading. After coming up with a particle setup we'll explore a cool way to create a wetmap from the particles using a 2D Houdini volume and COPs and thus avoiding shading artifacts, normally introduced by poor geometric resolution. A future part of the particle series will deal with shading the scene in Redshift.
