V-Ray for Rhino Manual - Rum

Adjust the Intensity
Default set the Intensity to 1. Below images are rendered with Intensity of 3 (left) and 5 (right).
Adjust the color
Default set the color to white. Click on the color box to change to a different color. Notice that if the
setting of the Intensity is too high, the color of the object itself will become close to white. Only the
light come out from this self-illuminated object will carry the correct color. So we recommend you not
to use this as a normal lightsource. Just make it as a decorative object in the scene.
Please refer to below image chart for results of various Emissive Intensities. By controlling the degree
of Transparency under the Emissive Color, you can still keep the diffuse color of the object. For
example, when the Intensity is higher than 2, the diffuse color is washed out and become white.
To avoid the self-illuminated object become white, please also refer to the Color Mapping
