Hi, many thanks for your appreciations guys!
Yes i used Particle Flow to create the rain in rendering.
Below is my setting for Particles, hope it 'll be usefull to you.
Thanks for sharing quick explanation of rain drops. However, I am still curious, does the described method adds the rains which are bouncing from table and terrace? Or it’s another trick?
I haven’t looked at the set up here, but I do know that Particle Flow lets you add things like deflectors, to bounce particles off of, so that could be done. Also, it allows you to spawn new particles when a particle hits something, so you could also set it up that way, so that an original rain drop particle can trigger a “mini explosion” of smaller particles, so it could be done that way too. Now, whether that’s contained in the setup, or was what was used in this scene, I can’t say But it would be possible to set it up so that the particle flow took care of all of that!
