AO render shpwing the meshes in the extension. I was lucky to have a lot of resources to pull from with premodeled rocks and Alien tech details.
Lighting pass before final render. This doesn't show the displacement on the Zbrushed rocks which really sold the look. In the film the aliens are stealing gold, hence the glowing yellow beams.
One of the environments from the film Cowboys and Aliens. The set was minimal with a partial wall of the ship and a lower chunk where Daniel Craig is standing.
Apart from the rocky backdrops, we also had to develop the strange crystalline structures that protruded from the sides of the ship. This was look developed in Mental Ray.
Another view of the Alien ship looking up towards the sunlight, the idea being the ship would drill down into the earth to get at the gold.
