3 animated 2D weather effects for Unity, free, one line of C# each. Every effect is a single shader on a single quad: no textures, no particle systems, sharp at any size.Works in any pipeline: the effects are unlit shaders on a quad each. Tested in Built-in, URP (2D and Universal Renderer) and HDRP. In HDRP the colours come out under HDRP's default exposure and post-processing unless the camera turns them off.3 animated 2D weather effects for Unity, free, one line of C# each.
