Best V-Ray Settings – GI Engines Choice

In this tutorial we will decide, which of GI rendering algorithms such as Brute force, Photon Map, Irradiance map, and Light cache, are the best for calculation of the global illumination. This tutorial answers the following questions. Which GI rendering algorithms are best in Vray? Which rendering engine should we choose for primary bounces and why? With what engine should we render the secondary bounces and why? What problems exist in GI maps and what should be done to eliminate them? Why does the noise or dirt on the fine detail of the scene appear? How to get rid of the smudges in the corn...
