11 OPTIMISE YOUR LIGHTING SETUP IN ARCH VIS
rather than concentrate on settings or parameters, at oxygen they follow an inductive process to set up the lighting according to real-world references
Light balance In order to balance lighting quickly and effectively, we generally start by assigning a neutral grey Vrayoverridemtl material to every object in the scene. This helps us to quickly see if the lighting is consistent with the geometry of the project. Once this is finished, we reassign the actual materials and refine the lighting scheme.
Camera Setting up your V-ray camera properly is an important part of lighting a scene. Find the best camera angle possible and keep as close as you can to aspect ratios used in real-world photography. Often the key to this kind of lighting workflow is to change the HDRI as little as possible and build your camera settings around it.
Contrast Always keep in mind the correct hierarchy between light intensity and colour temperature. To get more contrast, we usually play with the gamma setting of the VRAYHDRI map. A lower value will give more contrast, which means a bigger difference between light and shadow, and colours become more saturated.
Concept and references Good photographic references are crucial to achieve a good lighting scheme. The closer you get to the real world, the better it will be. Make sure to reproduce the natural behaviour of light in order to understand how the light is set, how it bounces off objects, how it casts shadows and what the colour of those shadows are.
