V-Ray for Rhino Manual - Rum

Please note that if any type of map is being used in Texture Editor, the Color and Intensity under
Emissive will no longer function. You can't use these two options to control the brightness of the
material any more. You need to click on the “M” and go back to the Texture Editor and adjust
brightness there. All other control options in the Texture Editor work the same like this.
Click on the “M” and go back to the Texture Editor window. Please pay special attention to below
options as these options are often used for controlling the Bitmap texture map.
Multiplier: Controls the intensity of the Bitmap. Default set to 1. Increase this number will intensify the
color tone, brightness and color contrast. Preview will not show much of difference if the value is too
small.
Blur under Bitmap: Control the blurriness of the Bitmap. Default set to 0.15. Set to 0 will not have any
blur effect to the Bitmap.
Override under Bitmap: Adjust the Gamma value of the
Bitmap. Increase the value will make the Bitmap
brighter. This parameter is also important for linear
workflow
Tile: Repeat the Bitmap texture on the object. Default
set to selected. When uncheck the Tile, you will see
only one Bitmap texture on the object.
UVW Repeat: Controls how many times a map is
repeated within a given space (either within the
surface, or within mappings)
UVW Rotation: Adjust the degree of rotation of the
Bitmap
The darker environment lighting will not affect the Bitmap setting for self-illuminated material (ipod
image). The Bitmap will still render as its own setting for brightness. Use the same way to create cold light
effect. Also showed below are two other examples.
