Examples of com.jme3.material.Material

com.jme3.material.Material
Material describes the rendering style for a given {@link Geometry}.
A material is essentially a list of {@link MatParam parameters}, those parameters map to uniforms which are defined in a shader. Setting the parameters can modify the behavior of a shader.
