This article explains the settings and values for the Corona Mixture shader in Cinema 4D.
Overview
The Corona Mixture shader allows for blending two input shaders (be it procedural shaders or texture images) and a "Mix strength" mask, using operations similar to blending modes commonly found in 2D compositing software.
Mix parameters
Mix operation – This parameter allows you to select the blending mode for mixing the base and the top layers.
Mix strength – This value controls the mixing intensity.
Mix texture – This parameter allows you to define a mixing texture (mixing mask).
Perform mixing in sRGB space – The "Perform mixing in sRGB space" checkbox makes the Corona Mixture shader operate in sRGB color space, which makes its results identical to those of 2D image editing software. Usually, there is no need to disable it.
Top layer
Level – This is the intensity (also considered as the visibility) of the color.
Contrast – This parameter controls the contrast of the Top Layer input.
Color – This parameter defines the color used for the near-surface from the objects defined in the "Distance from" list.
Texture – Defines the texture map or shader that is used for the near color.
Mix mode – Controls the blending mode of the texture map or shader.
Mix strength – Controls the intensity of the texture map or shader that is being used.
Base layer
Level – This is the intensity (also considered as the visibility) of the color.
Contrast – This parameter controls the contrast of the Base Layer input.
Color – This parameter defines the color used for the far-away surfaces from the objects defined in the "Distance from" list.
Texture – Defines the texture map or shader that is used for the far color.
Mix mode – Controls the blending mode of the texture map or shader.
Mix strength – Controls the intensity of the texture map or shader that is used.
