Animating rain

In our next project, let’s make it rain. We’re going to create a realistic effect by creating rain from the Rain particle template and making it bounce off the ground as you would see in a rainstorm. We’ll also create a puddle that will subtly grow and shrink, appearing to react to the falling rain, and it will also look like water, as we will add some blending options to it to give it a transparent look for a spectacular effect that even shows some of the ground underneath it.
