     * {@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 -

     * 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>

     * applied in this order (later RenderStates override earlier RenderStates):<ol>
     * <li>{@link TechniqueDef#getRenderState() Technique Definition's RenderState}

     * <li>{@link #getAdditionalRenderState() Material Instance Additional RenderState}
     * - 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>
