Weather particle systems define the appearance of weather like rain and snow. They are assigned to BSP clusters using Sapien and can be masked from localized areas using weather polyhedra.

Known issues

When the player is within a dense fog with a nearby opaque distance, weather particles will stop drawing even if set for the cluster containing fog. Ensure the opaque distance is sufficiently far away if weather particles in fog are desired.
