To
render global illumination
- First, make sure at least one light source
in your scene emits photons (see
Turn on photon emission for a light source).
- Select the Rendering menu
set.
- Open the Render Settings window.
Select
Window > Rendering Editors > Render Settings or
click the Render Settings window icon.
- Select the mental ray for Maya render.
- Click the Quality tab.
- From the Quality Presets drop-down
list, select Preview: Global Illumination.
Global
illumination (in the Rendering Features section
of the Features tab) is automatically
enabled.
- Render with the default settings.
If the default settings
are not sufficient to achieve the look you want (or to reduce render
speed), tweak the global illumination settings until you achieve
the look you want. See
Indirect Lighting tab for
more information.
TipIf your scene contains
caustics, global illumination or final gather, and you would like
to see those effect during mental ray IPR, in Render
View select IPR > IPR > Render
Settings.
