I made this still image a few weeks ago and decided it'd be fun to do a simple animation of the scene :-)
The animated tree was added for some dapple / interest with SpeedTree, the steam is just a 2d image sequence added in After Effects along with the grade.. This is the first animation I've been able to render out final frames completely on the GPU with VRayRT. Normally this simply isn't an option due to the size of scenes in architectural visualisations, or due to one technical limitation or another. Definitely a good option when you haven't got a farm at your disposal!
