V-Ray Geometry
the tessellation of the geometry data. By default the option is set to Low, which could produce jagged reflections on a seemingly smooth surface. Setting a higher option will generate more faces and produce smoother reflections. Note that every increase in the face count will slow down the render process. ExportDiffuse RE
that the Diffuse Filter Render Element is affected by reflection and refraction combined weight. This render element is, by itself, useful for making overall adjustments and enhancements to base colors and textures during compositing without affecting things like reflections and highlights.

physically correct illumination (energy distribution) in the scene, faster rendering, more convenient reflection and refraction parameters. Within this material you can apply different texture maps, control the reflections and refractions, add bump and displacement maps, force direct GI calculations, and choose the BRDFV-Ray Falloff

Here, we have a V-Ray Falloff texture mapped to the Reflection color of a V-Ray Material. The Falloff Direction Type is setGI Tab

GI caustics can be generated … , in addition to normal GI rays. This can speed up rendering of scenes with glossy reflections quite a lot. When you use this option, it is recommended to also enable
