I wanted to know how to go about make water drops come down the screen. How can I go about this? Any suggestions? Thanks.
An example of what im talking about is some what like this video: http://www.youtube.com/watch?v=a8195POVxxc
Just skip to 4:45.
Are you asking how to set it up in Unity or how to animate the water drops?
In Unity, your best bet would probably be to setup a separate camera to render water drops, set the clear flags to Don’t Clear, and then make it render above your main camera.
well i mean on how to write the shader for it. I dont know how to go about it. Is it just a blur effect on the screen?
