After watching Chris Kuhn's tutorial on how to make an Arc Reactor on YouTube I decided to give it a try. 24 hours later and this is my first pass result.
Modeled in Blender 2.65a, rendered using Cycles with AO enabled and 500 samples. The model is high poly - approx. 191K verts & 207K faces & 32 objects including control objects.
There are still a few details I need to add and hopefully I'll get around to adding some more interesting materials.
This is my first attempt at what I would consider a relatively complex hard surface model so please don't flame me too bad! ;)
Hope you enjoy it!
