When presented with this project for Leica Geosystems, they had a partially built scene in 3ds Max that had been incorrectly constructed as three separate scenes in addition to heavy Photoshop post-processing, instead of one complete environment.
Taking this and the need for additional adjustments into consideration, I opted to
re-create the whole environment in the Unreal Engine. This allowed instant feedback from changes thanks to it's real-time rendering capabilities. The graphic fidelity also improved without the need for additional retouching in Photoshop.
