Review the properties listed in the Material Contents table before adding new material properties.

To delete a property group, right-click the property group node (in the Model Builder) and select Delete (). The Basic property group cannot be deleted.

|
When material properties are added from the Basic node’s or a user-defined group node’s Settings window for Property Group, they are listed under Output Properties and Model Inputs in that Settings window.
|
•
|
When material properties are added from the Settings window for Material, the available material properties are listed under Material Properties and are added to the list under Material Contents with the property group listed. The list under Material Contents also contains material properties added from a subnode with a Settings window for Property Group.

A stop sign () indicates that an entry in the Value column is required. It means that the material property is required by a physics feature in the model but is undefined. When you enter a value in the Value column, the material property is added to its property group.

•
|
A green check mark () indicates that the property has a Value and is currently being used in the physics of the model.

In 3D components, the material is rendered including color and texture when Scene Light is active. In 2D models and in 3D components, when Scene Light is turned off, only a change of color is visible.
|
The texture and reflectance properties only take effect when the preference settings for the visualization are optimized for quality. When optimized for performance, the appearance includes color only. To set this, open The Preferences Dialog Box, click Graphics and Plot Windows, and click to select the Show material color and texture check box to display material texture and color.

Specular color is the color of the light of a specular reflection (specular reflection is the type of reflection that is characteristic of light reflected from a shiny surface).

|
Diffuse color represents the true color of an object; it is perceived as the color of the object itself rather than a reflection of the light. The diffuse color gets darker as the surface points away from the light (shading). As with Ambient color, if there is a texture, this is multiplied by the colors in the texture, otherwise it is as if it has a white texture.

Ambient color is the color of all the light that surrounds an object; it is the color seen when an object is in low light. This color is what the object reflects when illuminated by ambient light rather than direct light. Ambient color creates the effect of having light hit the object equally from all directions. As with Diffuse color, if there is a texture, this is multiplied by the colors in the texture; otherwise, it is as if it has a white texture.
