Curious about how memory efficient the release version of Brazil is? Here's a render by Andrew Harron who rendered out 3,060 instanced glasses totaling 100,759,680 polygons. The reflection depth was set to 1, and refraction depth set to 5. The memory usage for the scene was 1.66gb. For those wondering if instancing saves memory for Brazil, one of the splutterfishes said "instancing saves on some of brazil's memory, but the objects have to be there since the scene is fully raytraced."
