Rain

First, the number of raindrop particles is set, then a rainfall system is generated. Wind can change the direction in which the raindrops fall. In addition, the particle material is set to water by setting the refractive index (IOR) to 1.33, and cast shadow effects are enabled to enhance realism.

  • Heavy Rain (particles 5000)

  • Light Rain (particles 1000)
