ScreenDrops is a screen glare effect designed for use in both indoor and outdoor
maps. You can customize the glare materials and add as many layers of textures
as you want. It is aspect ratio independent and you can combine it with light
shafts for an even better looking effect!
Works in Unity and Unity Pro!
