Note that over bright colors may look the same as pure white but the GI results are different. Increasing the multiplier affects the GI solution and produces more light. You can use the VRayLightMtl as a light source assigned to an object.This parameter is not available when the renderer is set to GPU. If you specify 0.0, the light will be calculated for all surfaces. Larger values cut away more from the light lower values make the light range larger. This can be useful in scenes with many light sources, where you want to limit the effect of the lights to some distance around them.

Note that this currently does not work if the material is inside a Multi/Sub-object material.Ĭutoff – Specifies a threshold for the light intensity, below which the direct illumination is not computed. Any object to which this material is assigned turns into a light source, similar to a VRayLight Mesh light. On – When enabled, direct illumination is turned on.

For more details, please see the Notes section below. There are currently some restrictions on using these options. The controls in this section are intentionally simple if you need more control over the light source (exclude objects from illumination etc.), it is better to use a VRayLight instead.

The effect is equivalent to creating a VRayLight in Mesh mode for the same object. The controls in this section allow you to turn the objects with this VRayLightMtl material into actual direct mesh light sources.
