V-Ray Ambient Light is a V-Ray specific light source plugin that can be used to create light that doesn’t come from a specific direction. It can be used to simulate GI, ambient occlusion etc.

Mode – specifies which rays are affected by the V-Ray Ambient Light.

  • Direct + GI – affects both direct and GI rays
  • Direct Light – affects only the direct rays
  • GI – affects only the GI rays

GI min distance – specifies a distance from objects within which the GI rays will not be affected by the V-Ray Ambient Light.

Compensate exposure – this option has effect when the V-Ray Ambient Light is used along with the V-Ray Physical Camera. When checked this option ensures that the color of the ambient light is not affected by the exposure settings in the physical camera.
