Render a separate global illumination pass |
You can render global illumination separate from direct illumination in a separate pass.
During a global illumination rendering pass, direct illumination from light sources and ambient and incandescent material portions are disregarded. The following features are rendered (corresponding to the Maya render passes):
- colored backgrounds
- image planes
- certain shaders acting as incandescent emitters; for example, a Surface Shader.
To render a separate global illumination pass
- Select Window > Rendering Editors > Render Layer Editor.
- Open the Attribute Editor for the selected layer by doing one of the following:
- Select the desired layer and right-click Attributes.
- Select the desired layer and click its
button. - In the Attribute Editor, expand the Render Pass Options section.
- Turn on Global Illum under the Mental Ray section.
