Just a WIP previz work done with Maya. The animations weren´t used in the end.
All those washing machines are CAD models and imported into the scene as mental ray proxies. Poly count was at around 50 million. The mental ray proxies were exported once with materials and shaders and without, so those proxies without shader could be assigned with a new material, like occlusion and depth shader.
The pond surface is just a plane with the 2D ocean texture connected as a bump into a mia_material_x.
The same connection is done for the ocean shader.
The caustics in the pond are just animated grey scale caustic textures on the pond floor and walls. Those were taken from the substance shaders in Maya.
