A Substance shader is the link between a Substance asset and a Cinema 4D material.
The Substance shader can be found in the normal Cinema 4D Material Editor selection menu, as shown in the screenshot below:

To access the parameters of the Substance shader, you can either click the small arrow on the top left, or on the shader's preview image.
The Substance shader has two parameters:
- Asset: Here you can drop a Substance Asset from the Substance Asset Manager in order to link it to the shader. In other words, it will link a Substance asset to a Cinema 4D material channel.
- Channel: Select the output channel of the linked Substance.
