The Diffusion map component lets you apply an additional, second texture to modify the Diffuse component.
Click the Material Editor icon on the Main toolbar or press M. Click and hold the icon to show the flyout.

A Diffusion map puts a layer of dirt over a poster.
The Amount of the original Diffuse map is reduced to give it a faded look and highlight the Diffusion pattern.
Typically, you will want to reduce the Amount of this map to allow the main Diffuse map to show through.
For example, you might have a clean, bright image for a billboard. You use this image as the Diffuse map, and then use a second map as a Diffusion map to apply soot and city grime.
Procedures
To use a Diffusion color map:
- Click the map button for Diffusion.
3ds Max opens the Material/Map Browser.
- Choose a map from the Maps group, and then click OK.
(If you choose Bitmap as the map type, 3ds Max opens a file dialog that lets you choose the image file.)
- Use the map controls to set up the map.
Alternatively, you can use the
Slate Material Editor to
wire a map node to the Diffusion component.
