Station

This scene was a set construction for "Hephaestus" - a massive 3d short film headed by Alex Curtis. Alex and his crew provided me with the concepts and reference (fig. 01) and I set off to complete the modeling (fig. 02)

The shaders for this scene utilize a modular technique to break each surface texture up into it’s own shader. For the clock shader (fig. 03) a mix between a clean copper metal and a blackened patina material is used. Each material is created as separate mia_material_x and has its own individual specular, bump, and color propoerties alowing for much greater control. The two materials are then blended together using a 2d black and white image acting as a mask and a mib_color_mix node. The same system is utilized on the floor shader to blend between 2 marble textures and a layer of dust (fig. 04)

The lighting for the scene was fairly simple. There are only 2 lights - a directional light for the sun, and a portal light casting light from the sky in through the holes in the roof (fig. 05)

Next up was light fog. I opted to go Mental Ray's slower, but much more accurate and awesome, parti_volume. The parti_volume node is a full volume shader that accurately simulates the way light reflects through simulated particles in the air. It was rendered in a separate pass for greater control in the composite (fig. 06)

After rendering out the occlusion, zDepth, and color alpha layers the scene was brought into After Effects and composited together.
