I had posted this model in my sketchbook. Since then, I’ve tweaked the material a bit. Rather than another render of it alone, I figured it would be neat to throw together a scene. So here is this reactor/collider thingy which has fallen to the ground. Perhaps there is more wreckage yet to be found.
Terrain is an ANT landscape. Gravel, stones, and plants are from Scatter. I used JSPlacement and Gimp to create the displacement map for the torus.
