     * <ul>
     * <li>Determine which technique to use to render the material -
     * either what the user selected via
     * {@link #selectTechnique(java.lang.String, com.jme3.renderer.RenderManager)
     * Material.selectTechnique()},

     * {@link Technique#makeCurrent(com.jme3.asset.AssetManager, boolean, java.util.EnumSet)
     * Technique.makeCurrent()}.
     * If the technique wants to use a shader to render the model, it should load it at this part -
     * the shader should have all the proper defines as declared in the technique definition,
     * including those that are bound to material parameters.
     * The technique can re-use the shader from the last frame if
     * no changes to the defines occurred.</li></ul>
     * <li>Set the {@link RenderState} to use for rendering. The render states are
     * applied in this order (later RenderStates override earlier RenderStates):<ol>
     * <li>{@link TechniqueDef#getRenderState() Technique Definition's RenderState}
     * - i.e. specific renderstate that is required for the shader.</li>

     * - i.e. ad-hoc renderstate set per model</li>
     * <li>{@link RenderManager#getForcedRenderState() RenderManager's Forced RenderState}
     * - i.e. renderstate requested by a {@link com.jme3.post.SceneProcessor} or
     * post-processing filter.</li></ol>
     * <li>If the technique {@link TechniqueDef#isUsingShaders() uses a shader}, then the uniforms of the shader must be updated.<ul>
     * <li>Uniforms bound to material parameters are updated based on the current material parameter values.</li>
     * <li>Uniforms bound to world parameters are updated from the RenderManager.
     * Internally {@link UniformBindingManager} is used for this task.</li>
     * <li>Uniforms bound to textures will cause the texture to be uploaded as necessary.
     * The uniform is set to the texture unit where the texture is bound.</li></ul>
     * <li>If the technique uses a shader, the model is then rendered according
     * to the lighting mode specified on the technique definition.<ul>
     * <li>{@link LightMode#SinglePass single pass light mode} fills the shader's light uniform arrays
     * with the first 4 lights and renders the model once.</li>
     * <li>{@link LightMode#MultiPass multi pass light mode} light mode renders the model multiple times,
     * for the first light it is rendered opaque, on subsequent lights it is
     * rendered with {@link BlendMode#AlphaAdditive alpha-additive} blending and depth writing disabled.</li>
     * </ul>
     * <li>For techniques that do not use shaders,
     * fixed function OpenGL is used to render the model (see {@link GL1Renderer} interface):<ul>
     * <li>OpenGL state ({@link FixedFuncBinding}) that is bound to material parameters is updated. </li>
     * <li>The texture set on the material is uploaded and bound.
     * Currently only 1 texture is supported for fixed function techniques.</li>
     * <li>If the technique uses lighting, then OpenGL lighting state is updated
     * based on the light list on the geometry, otherwise OpenGL lighting is disabled.</li>
