During my time at Buildmedia/The Boundary, I had the pleasure to produce some Architecture visualisation projects that are hyper-realistic & real-time interactive using UE4.
One of the main projects that I was responsible of was Lendlease Ardency based in Malborne. From blockout, modelling, texturing, to refining the styling guide from client, lighting & rendering in Unreal Engine. The skybox was created with photos and processed with PTGui.
The work was built entirely within UE4, it was to offers prospective buyers a chance to explore their future homes before the foundations have been laid in fully real-time, photo-realistic detail.
