mr Labeled Element

Notemental ray shaders appear in the Browser only if the currently active renderer supports them.

The mr Labeled Element shader doesn’t actually function as a shader, but instead works in conjunction with the mr Labeled Element render element to let you output any branch of a shader tree (a string of nested maps) as a render element. For example, if you use the Checker map as a diffuse map, and you use a Perlin Marble map as one of the two checker colors, you can render only the checker-map components that contain the marble map to a custom element for subsequent compositing.

Interface

Shader/Map to Store (Passthrough): Click the map button to assign a shader or map or shader/map branch to be passed to the render element. If a shader or map is already assigned, the button is labeled “M”; click the button to edit the shader or map.
Label: Enter the same name as that assigned to the render element.
