Weather Tool for Unreal Engine

James Stone has recently released a highly modifiable and easy to use weather system that will let you easily set up rain, snow, hail, lightning, sound effects, and onscreen post process.

The pack features tons of parameters to change for a desired weather style result: rain with wet ground features, snow with snow buildup on ground, hail that physically bounces and breaks upon impact, sheet and bolt lightning, clouds and onscreen post process effects like rain dripping and ice.
