Details (CineRender Global Illumination)

These settings are available, as part of the optional Global Illumination effect, in the Detailed view of PhotoRendering Settings for the CineRender engine.
Tip: In order for this parameter to work, the surface channel “Color” must be disabled and no texture should be present in the Transparency channel.
Tip regarding reflected GI Caustics: Reflected GI Caustics always require an active Reflectance surface channel. Otherwise, you can achieve the best quality caustics if GI Method is set to QMC.
