Cycles Rain

Hi, any tips for compositing rain with Cycles?

Basically i’m after using a technique like this, e.g. using the Vector Layer.

Currently i’m playing with getting the rain using matte color key, but…

Any ideas or other methods welcome!

Cheers!

can’t be done only in cycles at the moment
you’ll have to use BI render passes and combine it with the cycles render in the compositor

I think I got it (your way)

Basically copied the rain and stuff which gets in the way to another scene, and…

nodes

*** But it looks like i’ll have to slow my rain down since it’s going a little dotty…
