Corona Mixture Shader - C4D
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. The available blending modes are:
- Minimum (Darken)
- Maximum (Lighten)
- Color Dodge
- Color Burn
- Linear Burn
- Linear Light (Add Sub)
- Soft Light
- Hard Light
- Vivid Light
- Pin Light
- Hard Mix
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.
How to use it
The use of this shader is simple, you can create a Corona Material and load the Corona Mixture shader in any available texture slot where you require to mix either color or texture maps.
You can start by defining a texture map or color for the "Base layer" section, another texture map or color for the "Top layer" section, and finally define how these are going to be mixed ("Mix operation").
Additionally, you can adjust the presence of the top layer by using the "Mix strength" value, and the mixing mask (in case you need one).
Examples of use
In this example, we've used a Corona Multi shader to influence and modify the visual perception of the palm leaves color.
