Bathtub

A late update.

First try on fluid simulation. The fluid simulator is very hard to use, given that the accuracy is not high enough. For a still image, each droplet must be manually adjusted; otherwise, the droplets will go halfway through the walls.

Most of the time was used to edit the water. I didn't pay much attention to the bathtub, and I think it is too reflective and too smooth. Luckily it is blocked by vapour.
