Use the sliders to change the looks of the rain and background. -Press 'Space' to hide variables. -Press 'M' to mute sounds. -Press 'R' to make the rains color RAINBOW. -Press 'Right-Arrow' to switch backdrops (I recommend the woods). -Press 'S' for slow-motion, so you can see the lighting in action!
I was messing around and animating a mouse trail, (Mangodream-), and eventually thought to make rain with the particle effect.
