This page provides information on the V-Ray Marble Texture. Overview The Marble texture map can be used to generate a procedural marble texture. It uses two colors that can also have texture maps assigned to them. Any texture can be replaced via the  Replace With New Texture  ( ) button, which activates when you select the texture to be replaced. If the texture is an instance, all copies are changed as well. Parameters Color Base  – Specifies the main color of the marble.  All parameters in this section can have a texture map assigned to their channel, as long as the checkbox is enabled.  Color Vein  – Specifies the color of the marble's veins Vein Width  – Controls the thickness of the marble veins. Diffusion  – Controls the amount of blur applied to the veins. Contrast  – Controls the contrast. Noise Attributes Amplitude   – Controls the amount of distortion in the marbles vein's. A value of 0 makes these a straight line.  Ratio  – Controls the fractal noise frequency (from low to high frequency). Ripples  – Controls the scale of the fundamental frequency of the fractal nous used in the texture. Depth Min  – Minimum level of the fractal noise. Depth Max  – Maximum level of the fractal noise. Color Manipulation Invert Texture  – Inverts the RGB texture values. Alpha from Intensity  – Uses the texture RGB intensity/luminance as alpha channel. Color Gain  – Corrects the color of the texture by multiplying the the RGB color values in the texture with the RGB color values specified here. When a texture is selected, it overrides the color as long as the texture checkbox is enabled.  Color Offset  – Corrects the color of the texture by adding the RGB color values specified here to the RGB color values in the texture. When a texture is selected, it overrides the color as long as the texture checkbox is enabled.  Default Color  – Specifies a default color used for polygons with no valid UVs. In case the map is not tiled, specifies a default color that is used outside the texture square.  When a texture is selected, it overrides the color as long as the texture checkbox is enabled. Multipliers Mode  – Specifies the multiplication mode of the colors.  Multiply  – Multiplies the RGB numbers for each pixel of the top layer with the RGB number of the corresponding pixel from the bottom layer. The result is a darker picture. The color used for blending is black. Blend Amount –    Takes each pixel from the top layer if present. Otherwise the bottom layer is used. The color used for blending is the one specified in the color slot. Color Base  – Blends between a color and a texture, if specified. Color Vein  – Blends between a color and a texture, if specified.
