This page provides information on the Brute Force rollout under the GI tab in V-Ray's Render Settings.
The Brute force method for computing global illumination recomputes the GI values for every single shaded point separately and independently from other points. This method is very accurate, especially if you have many small details in the scene.
To speed up Brute force GI, you can use a faster method for approximating secondary GI bounces, while using the brute force method for the primary bounces.
The Brute force GI rollout appears only when the Brute force method is selected as a Primary engine or Secondary engine within the Global Illumination rollout. For more information on how the Brute force GI calculations work, please see the Brute Force GI page.
