The Material editor can be opened from the material management tab in the panel. It lets you edit materials you created or loaded from the library.

# Material Library

## The material library window.

There are two panels in the material library :

The tree panel

The material library tree represents folders of pre-defined materials organized by categories. For instance, for a gold material follow Metals->Golds. You can add your own materials to the library by copying tvs files where the library is installed ( usually /usr/share/truevision/materials/... ), in the correct subfolder. You can also add materials without logging as root ( in ~/.truevision/materials/... ) but materials won't be visible for other users.

The selection panel

On the right side you can see a browser where thumbnails of materials previews are displayed. To select one, just click on his name. On the bottom his name, his authors and related comments will be displayed. To load this material click 'Ok'. To load the material without closing the material library, click 'Apply'.
