Global Illumination (Cineware)

This effect is available in the Detailed view of PhotoRendering Settings for the Cineware engine.

Global Illumination (GI) is a sophisticated method for achieving realistic lighting effects in your model. The algorithm simulates the effects of not just direct light sources, but indirect light effects - that is, inter-reflections caused by light rays bouncing off surfaces.

With Cineware, you can achieve very high-quality renderings using Global Illumination. However, it can greatly increase render time.
