Rain, research

Today I did (among other things) a lot fo research on what to do with 2D rain. I am still a bit uncertain about this kind of rain on top of 3D. But fact is, it may just be a lot quicker to do the rain in 2D. we have some closeups of something on the ground, and rain pouring down, which means we need some way to show the contact with the ground. My main source of inspiration on this is Howl's Moving Castle and My Neighbor Totoro.
I hope we can do camera moves along witht his as well..
