Invisible – Controls whether the shape of the VRayLight source is visible in the render result. When disabled, 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 invisible lights 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). Affect Diffuse – Determines whether the light is affecting the diffuse properties of the materials. Affect Specular – Determines whether the light is affecting the specular of the materials. This means glossy reflections. Affect Reflections – Determines whether the light will appear 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 VRayEnvironmentFog, VRayVolumeGrid or Phoenix effects. |
