Detail this asset from Unity Store: Original Link
Cartoon Rain & Blood Rain v1.1
This package is a collection of rain particle systems with raindrop, ripple, bubble and splash effects. All rain particles support Wind Zone. There are 3 levels of rain prefab (Light Rain, Moderate Rain and Heavy Rain) in this package, each of which has a ‘blood rain’ version. You can just drag-n-drop one prefab into your scene to add the rain effect!
Contains:
– 12 rain prefabs.
– 4 demo scenes.
– 4 textures for raindrop, ripple, bubble and splash.
– 1 ‘bad weather’ skybox.
The demo scene is located in the folder “AssetsCartoon Rain & Blood RainDemo Scene”.
This asset is independent and does not require other asset to work. But this package still provides 2 demo scenes to show how to work with the unity Standard Assets. So before testing ‘demo scene 3’ & ‘demo scene 4’, please import the unity Standard Assets. You can just import the ‘Water’ folder (‘Standard Assets Environment Water’).
