Use
You can use the Materials tab page to define the export properties for the selected file format’s materials.
Features
The generic material options are as follows.

Functional Description |

Change all Materials before Export |
Activates the file’s material property fields and applies the settings when the file is saved |
|
Substitute color of textured material to |
Sets the diffuse color to the selected color, if a diffuse texture is present |
|
Set Ambient Color to |
Applies the selected color as the ambient color. Ambient light is the general light that illuminates the entire scene. It has uniform intensity and is uniformly diffuse. It has no discernible source and no discernible direction.
|
|
Set Diffuse Color to |
Applies the selected color as the diffuse color. Diffuse color describes how a material reflects diffuse light in a scene. Because most scenes contain much more diffuse light than ambient light, diffuse reflection plays the largest part in determining overall color. Additionally, because diffuse light is directional, the angle of incidence for diffuse light affects the overall intensity of the reflection. Diffuse reflection is greatest when the light strikes a vertex parallel to that vertex normal. As the angle of reflection increases, the effect of diffuse reflection diminishes. The amount of light reflected is the cosine of the angle between the incoming light and the vertex normal.
|
|
Set Specular Color to |
Applies the selected color as the specular color. Specular reflection creates highlights on objects, making them appear shiny. You establish the color of the specular highlights by setting this color.
|
|
Set Emissive Color to |
Applies the selected color as the emissive color. This parameter models “glowing” objects. This can be useful for displaying pre-lit models (where the light energy of the room is computed explicitly), or for displaying scientific data.
|
|
Set Opacity of all Transparent Objects |
If the material opacity is less than 1, replaces the opacity value by the specified value |
|
Set Glossiness to |
Changes the material’s glossiness to the specified value |
