As with my Hires rain this is a low res 640 x 480 version good for most low res stages.  30 frames of rainy bliss, no more worries that the rain looks good, rendered using a particle system in 3Dsmax 6 this rain falls pretty realistically, simply add it as the foreground and use mask and transparency.  I used the hires video as a demo.
