I got inspired by my previous paint video, so I decided to try Dynamic Paint with a bit heavier scene.
Result, Realistic Rain:
It features total 500.000 rain particles. Cool thing is that the ground visual is all material+texturing, generated with Dynamic Paint. Every single wet spot and splash is real interaction with those 500.000 particles!
Making of is quite simple: paint texture affects ground darkness and specular, plus a fast drying wetmap is used as bump texture and to add those white splashes.
This scene also helped Blender become more stable. I found a quite nasty particle system bug while trying to render this. After reporting it to jahka it got fixed. :)
