Group materials and Material editor

Group materials

The Openspace3D "Group materials" tab shows every material loaded in the group. It allows you to create, edit, delete and assign your materials.
Selecting an object in the 3d edit interface automatically select its material in this tab.

IMPORTANT NOTE : Every addition, edition or deletion is definitely saved only after the scene is saved. Exiting a scene without saving it will cancel every change realized on the materials since the last save.

"Group materials" tab exemple with a few materials :

Icon	Name	Definition

	Add	Add or create a new material for the group. See below for more details.
	Delete	Delete the selected material.
	Assign	Assign the selected material to the selected object in the 3D edit interface.

When you want to add a new material, you are faced with this interface :

The first field is the name of your material. it is filled with a default name, that you can change.

The second field is the location where your material is saved. If you select an already existing .material file, the material(s) in this file will be loaded. If you enter a new file name, a new material will be created.
