This page provides information about the Surface Properties node in the V-Ray Node Editor in Blender.
Overview
The surface Properties node provides additional surface properties on a per-object basis. Make sure that this node is connected to the V-Ray Object Output node, or it will not be applied to the currently selected object.

Properties
Generate GI Multiplier – Determines whether the indirect illumination generated by the object is multiplied. A multiplier of 1 keeps the indirect illumination at the same value.
Receive GI Multiplier – Determines whether the indirect illumination received by the object is multiplied. A multiplier of 1 keeps the received illumination at the same value.
Subdivs Multiplier – Specifies a multiplier for the subdivisions of all secondary ray tracing done for the particular surface.
Caustics Multiplier – Specifies a multiplier for the caustics generated by the selected object. A value of one makes no changes.
GI Surface ID – This number can be used to prevent the blending of light cache samples across different surfaces. If two objects have different GI surface IDs, the light cache samples of the two objects are not blended. This can be useful for preventing light leaks between objects of vastly different illumination.
Generate Render Element – When disabled, the Surface Properties do not affect the results of the generated render channels.
