Material commands

The Plugins > C4DtoA > Materials menu contains some useful commands to help working with the Arnold Material.

Create new Arnold Shader Network material

This command adds a new Arnold Shader Network Material to the scene and opens the network editor.

Default shortcut is Alt+W~N in the Material Browser.

Convert the selected C4D Material to an Arnold Material

Adds a new Arnold Material to the scene with the shader network converted from the selected C4D Material.

Note that the resulting Arnold Material won't be a perfect match to the C4D Material since Arnold has different shaders and concepts. See the Cinema 4D Material page for the supported features and limitations.

Default shortcut is Alt+W~C in the Material Browser.

Replace the selected C4D Material to an Arnold Material

Creates a new Arnold Material with the shader network converted from the selected C4D Material and replaces the original C4D Material in the scene with the new Arnold Material.

Default shortcut is Alt+W~M in the Material Browser.

Convert the selected Substance Asset to an Arnold Material

Adds a new Arnold Material to the scene and builds a shader network according to the selected Substance Asset. The main node in the network is a standard shader. A Substance Shader is created for each texture of the asset and connected to the right parameter.

Substance textureColor spaceArnold shader network
Base colorsRGBConnected to the Diffuse color of the standard shader.
DiffusesRGBConnected to the Diffuse color of the standard shader when no Base color texture exists.
SpecularsRGBConnected to the Specular color of the standard shader. Specular weight is set to 1.0, the Specular distribution is set to GGX.
RoughnesslinearConnected to the Specular roughness of the standard shader.
f0linearConnected to the Reflectance at normal of the standard shader. Specular Fresnel is enabled.
NormallinearA normal map shader is created and the texture is connected to its Normal map parameter.
BumplinearA bump2d  shader is created and the texture is connected to its Bump map parameter.
DisplacementlinearA normal displacement shader is created and the texture is connected to its Displacement parameter.
ReflectionsRGBConnected to the Reflection color of the standard shader. Reflection weight is set to 1.0.
RefractionsRGBConnected to the Refraction color of the standard shader. Refraction weight is set to 1.0.
EmissionsRGBConnected to the Emission color of the standard shader. Emission weight is set to 1.0.
OpacitysRGBConnected to the Opacity of the standard shader.
MetalliclinearMixes between the Specular texture and a complex IOR shader with the Base color as Reflectivity and the Specular as Edge tint. Connected to the Specular Color of the standard shader.

Default shortcut is Alt+W~C in the Substance Asset Manager.

The command is available only in CINEMA 4D R18 and above.
