Photo-Realistic 3D Shower and Faucet Sprays

Did some particle experimentation at work on my down time, and made these faucet sprays while trying out RealFlow.
These are stills taken from my RealFlow simulations, and rendered with V-Ray in 3DS-Max, with a bit of touching up.

Process (Brief)
I chose these sprays because they have a lot of different paths for particles to take.
I converted engineering .stp files to .obj files.
The .stp files from the engineers are extremely precise. They even have the tiny nozzles on the aerators modeled out to the exact detail. I used the aerator geometry to create emitters that spray particles along the correct normal.
Exported the particle flow as an .obj from RealFlow, made shaders and a studio in 3DS Max, and rendered away with V-Ray. Composited in Photoshop.
