Rain Issues

This effect is proving somewhat impractical to render. Mainly due to the heavy use of Refractions in the materials. I think that with some tweaks to the lighting, the actual effect will look allright though.
I have attempted to render it in realtime using a CGFX shader, but this did not work either.

I am going to try reducing the fog effect to see if that is an acceptable solution.
Oh, and I do want to try some water effects within Maya 2015's new Bifrost system.
