Welcome to the first of the six-part tutorial series, discussing possibly the most challenging kind of 3D environment: interiors. mental ray (for Maya) users typically get cold feet and sweating fingers when it comes to this “closed combat”; the royal league of environment lighting.

Global Illumination, Final Gather and Caustics, these are the three individual elements that we commonly use as 3D artists to simulate the effects of bounced and focused light.
We will explore each of these in the following sections with theory and practice. Global Illumination The underlying principle of Global Illumination is that light, in the real world, can exhibit the ability to reflect off of any surface.
