Uses new material system for appearance Each feature object now has a property called ShapeMaterial that describes its physical properties. If it has a shape, it has a material. The ShapeColor attribute is replaced by a ShapeAppearance attribute. This is a material list that describes all appearance properties, not just diffuse color. As a list in can be used for all elements of a shape, such as edges and faces. A new widget is provided to allow the user to select materials in a consistent fashion. It can also launch the material editor with its more advanced capabilities.
