Emissive Layer

The Emissive material layer is created with the Add Layer option in the V-Ray Asset Editor. The parameters are the same as the the Emissive material however, this layer can not be overridden.

Emissive

Color – Specifies the color of the light. A texture can be specified as well. See the Color and Texture examples below for more information.

Intensity – Controls the strength of the light.

Transparency – Specifies the color that is transparent. For this parameter black stands for opaque and white for transparent color. A texture can be specified as well.

Emit On Back Side – When enabled, the object emits light from its back side as well. When disabled, only the front side emits light, and the material renders as black on the back sides.

Compensate EV – Used when rendering with the V-Ray Physical Camera. When enabled, the intensity of the material is adjusted to compensate for the camera exposure.

Color *Opacity – When enabled, the color of the light material is multiplied by the opacity texture. Otherwise, the color and opacity act independently (so-called additive transparency).

Multipliers

Mode – Specifies one of the following methods for adjusting textures.

Multiply – Multipliers can be specified to adjust colors and textures.
Blend Amount – Blend amounts can be specified to adjust colors and textures.

Color – Controls the intensity of the Emissive Color (light color).

Intensity – Controls the strength of the light.

Transparency – Controls the intensity of the Transparency Color, which determines the color that is transparent.
