I started on this a long time ago and I am now going to finish it. Based on a concept by Thomas A. Szakolczay for Call Of Duty: Ghosts.
Blockout work from a while ago:
With some additional angles I will be working with in mind:
I have been slowly chipping away at some assets that I will post. Once I've finished a few of these (around the desk area) I will push this blockout into the latest version of UE4, and further improve the lighting. There's a lot of interest lost in the current blockout regarding lighting.
I have made a few small alterations with the direction - mainly that the large security door doesn't open up to a warehouse looking floor, but instead a walk-in safe. I originally saw this concept and wanted to pursue it before playing the video game; so I've disregarded what its intention and implementation was.
