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.

Fields and Checkboxes

Functional Description

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.

  • Or Scale By: Multiplies the ambient color by the specified value

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.

  • Or Scale By: Multiplies the diffuse color by the specified value

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.

  • Or Scale By: Multiplies the specular color by the specified value

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.

  • Or Scale By: Multiplies the emissive color by the specified value

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
