TIP When rendering A&D elements for compositing in Autodesk Combustion, bear in mind that Combustion does not support HDR imagery, so to avoid clamping it will be necessary to adjust the Multiplier value for each element. Apply Shadows When on, the output includes shadows cast on the surface. mr Labeled Element Parameters Rollout Rendering menu/main toolbar > Render Setup > Render Setup dialog > Render Elements panel > Render Elements rollout > Add button > Render Elements dialog > Add mr Labeled Element to the elements list (or highlight an mr Labeled Element entry in the list). The mr Labeled Element is a render element that lets you output one or more branches of a material tree to a custom render element. (A branch comprises a map or shader and any sub-elements, such as maps assigned to the map's map slots.) To use this element, assign the mr Labeled Element shader on page 6003 as the parent of the branch to render, give it a label, and then use the same label for the render element. For details, see the following procedure. Procedure To use the mr Labeled element: 1 In the Material Editor, determine which branch of a material to output as a separate element. For example, an Arch & Design material might contain a Gradient map assigned as a Diffuse > Color shader, and one of the Gradient maps could be assigned a Checker map, and one of the Checker maps could be assigned a Noise map. This procedure will assume you want to render the Checker map and its constituent Noise map to an element. So the material structure would be like this: A&D material > Gradient (Diffuse Color) > Checker (Gradient Color #1) > Noise (Checker Color #1) 2 In the Material Editor, click the map button at the top of the branch you want to output. In this example, you'd click the Diffuse > Color map button in the Arch & Design material to open the Gradient map settings. You'd then click the first map button (Color #1) on the Gradient Parameters rollout to open the Checker map settings. mr Labeled Element Parameters Rollout | 6363
