Diffuse

The Diffuse node lets you adjust the color of an illuminated material in a scene. The material appears darker as the surface points away from the light.

Inputs and Controls

Connection Type	Connection Name	Function
Input	map	The image used to modulate the diffuse properties of the material.
unnamed	Either: • The 2D image you’re using for the surface texture, or • Another shader node, such as Diffuse, Specular, or Emission. Adding several shader nodes one after the other allows you to produce more complex effects.

map

The image used to modulate the diffuse properties of the material.

unnamed

Either:

• The 2D image you’re using for the surface texture, or

• Another shader node, such as Diffuse, Specular, or Emission. Adding several shader nodes one after the other allows you to produce more complex effects.

Control (UI)	Knob (Scripting)	Default Value	Function
Diffuse Tab
channels	channels	rgba	The effect is only applied to these channels. You can use the checkboxes on the right to select individual channels.
white	white	0.18	The color of the material when illuminated. Note that when you have an image connected to the unnamed input of the node and adjust this value, you need to look at the rendered 2D image to see the effect of your changes. Changing the white value does not have any effect in the 3D Viewer.
