Here's a bundle with some assets to add rain and hail effects to your scene. Includes the following:

• Falling rain particles (With and without ground ripples/splatter).
• Storm clouds.
• A wet floor effect to make any surface look like it has puddles on it.
• Various premade combinations of the above.
• Falling hail particles (With and without ground collision)
• 6 Varying intensity rainfall, thunder and hail sound effects.

Play around with the scale and stack multiple atoms to simulate heavier/softer effects.

Turn off collision on the CustomUnityAsset if you already have a ground surface in your scene.
