The Mix (Map) texture allows for two textures or other sources to be blended together.
Mix (Map) texture is called Mix texture in all versions until V-Ray version 3.60.
Texture A (bottom) – Specifies the first texture to be blended.
Texture B (top) – Specifies the second texture to be blended.
Mix Map – The color or texture (grayscale) assigned here controls the opacity of Texture B.
Mix Curve – Enables or disables the mix curve.
Transition Upper – Specifies the upper threshold for transitioning between the two sources.
Transition Lower – Specifies the lower threshold for transitioning between the two sources.
Mode – Specifies the multiplication mode of the colors.
Multiplier – 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.
Blend Amount– Takes each pixel from the top layer if present. Otherwise the bottom layer is used.
Texture A (bottom) – Controls the intensity of the source A texture.
Texture B (top) – Controls the intensity of the source B texture.
Mix Map – Blends between a color and a texture, if specified.
