 A Geometry (mesh) is just the shape of the object. jMonkeyEngine cannot render a shape without knowing anything about its surface properties. You need to apply a color or texture to the surface of your Geometries to make them visible. In jMonkeyEngine, colors and textures are represented as Material objects. (An alternative would also be to load a model that includes materials generated by a mesh editor, such as Blender.)
 
 *  All Geometries must have Materials that defines color or texture.
-*  Each Material is based on a Material Definition file. +Examples of included Material Definitions: Lighting.j3md, Unshaded.j3md

 You want to make the most of your 3D models by specifying good looking material parameters. The developers must be in contact with the graphic designers regarding which of the <<jme3/advanced/materials_overview#,Material properties>> they intend to use in their 3D models. You must have an understanding what <<jme3/terminology#materialstextures,texture maps>> are, to be able to use texture-mapped materials.

-It can happen that you load textures at different scales, for example, your blades of grass may look as big as twigs, or your spaceship's heat tiles may look like small bathroom tiles. Then you need to adjust the texture scale, either bigger (< 1.0f) or smaller (< 1.0f).
