I've spent the last week building a number of props that will be scattered about the laboratory. While they add to render times, they are necessary components to sell the world.
Also to sell the world are some features to dial back some of the sterility of the locations. Interest elements like pipes and a new feature to the ceiling were installed to make the place feel less eascetic. One of the intentions for a final pass is a layer of dirt and grime, partially achieved by the ambient occlusion from the pipes and tables but more still needs to be added to make the whole thing convincing.
Also to sell the world: Some experimentation with photogrammetry and more general texture maps to sell a convincing texture for the world being built. This experimentation has so far been interesting, I was surprised at some of the difference it makes to making an object convincing.
