Here are some more shots of the tech environment and props I made in Unreal. It was all modeled in Maya and the AO and wear bake was done in Substance Painter.

I started this set by blocking out the main wall and floor pieces. Then got the scale and fit of everything in order before working out the style and then dug in for a long set of modeling all 500+ pieces. Turned out to be a pretty fun set to build levels with though.
