Invisible – Controls whether the shape of the V-Ray Mesh Light source is visible in the render result. When this option is turned off, the source is rendered in the current light color. Otherwise, it is not visible in the scene. Note that this option only affects the visibility of the light when seen directly by the camera or through refractions. The visibility of the light with respect to reflections is controlled by the Affect specular and Affect Reflections options. Occlude Other Lights – Controls the behavior of the light when Invisible is enabled in relation to other light sources. When enabled, the light blocks the lighting from other lights as if it's visible. Also, in reflections, the light behaves as it's visible and occludes other lights. When disabled, the light is transparent for other lights and does not occlude them. This option doesn't affect visible lights (as they always occlude other lights) and dome lights (which are always additive). Double Sided – Controls whether light is emitted from both sides of each face. Affect Diffuse – Determines whether the light affects the diffuse properties of the materials. Affect Specular – Determines whether the light affects the specular properties of the materials. This means glossy reflections. Affect Reflections – Determines whether the light appears in reflections of materials. This means both perfect and glossy reflections. Affect Atmospherics – When enabled, the light influences the atmospheric effects in the scene. Diffuse Contribution – A multiplier for the effect of the light on the diffuse. Specular Contribution – A multiplier for the effect of the light on the specular. Atmospherics Contribution – Determines the amount of influence the light has on the atmospheric effects, such as Environment Fog or V-Ray Volume Grid. Ignore Lights Normals – When this option is disabled, more light is emitted in the direction of the source surface normal. LPE Label – Allows a label to be assigned, which can be used to reference the light in a Light Path Expression. This is especially useful when working with the Light Select render element to evaluate custom light contribution in the scene. |
