3 Click the map button just above the map rollouts on the right side of the Material Editor (in this example, Checker) to open the Material/Map Browser. 4 On the Material/Map Browser, double-click the mr Labeled Element item. This opens the Replace Map dialog. 5 Make sure "Keep old map as sub-map?" is chosen, and then click OK. 6 You now see the mr Labeled Element Parameters rollout. If you click the Shader/Map To Store (Passthrough) button, labeled "M", you can access the branch that will be output to the render element: the Checker map containing the Noise map. 7 If you clicked the M button, go back up to the parent mr Labeled Element shader, and then enter a name for the element in the Label field. In this example, the name could be checker/marble branch. The material structure would now be like this (new map in italics): A&D material > Gradient (Diffuse Color) > mr Labeled Element shader (Gradient Color #1) > Checker (mr Labeled Element shader map) > Noise (Checker Color #1) 8 On the Render Setup dialog > Render Elements panel > Render Elements rollout, click Add. Choose the mr Labeled Element item from the list. 9 On the Parameters rollout for the element, enter the name you specified in step 7 in the Label field. 10 Set up the other Render Element parameters as necessary and then render the scene. Your custom element is rendered to an image file. The following illustration shows the example described in the preceding procedure. The left-hand image shows the full material, with the Noise inside the Checker inside the Gradient, and the right-hand image shows a labeled element containing only the Noise inside the Checker. The element renders only the part of the Checker map that is used by the Gradient map. 6364 | Chapter 20 Rendering
