A power transfer corridor from the latest scene of Giants of the Earth:
NIce scene. Thanks for your generosity.
And BTW-- since the question has been asked -- this is unrelated to Andrew Price's tutorial. This is actually based on a dozen images of Submarine tunnels along with some industrial design provided by yours truly. Though when its all said and done, its a pretty simple scene that worked well for the few shots it was needed
The colors you used remind me a lot of the Damnation level from Halo CE
well, I've never played the game, but any time I am compared to pros, I'll take that as a compliment!
