Use shadow linking to link light sources with surfaces so that selected objects only cast shadows from light sources with which they are linked. This technique is similar to light linking except that it controls shadow calculations rather than illumination calculations.
Refer to the following links for descriptions on how to create or break shadow links between lights and surfaces:
To link selected lights to surfaces using shadow linking (if rendering with Maya Software renderer)
- Select the lights and surfaces you want to link.
- In the
Rendering menu set, select
Lighting/shading > Make Shadow Links.
- When rendering with
Maya Software, you may render shadow links via raytraced shadows or depth mapped shadows.
- If you render via raytraced shadows, click on each light source and select
Use Ray Trace Shadows in the light’s
Attribute Editor. In the
Render Settings
window, enable
Raytracing.
- If you render via depth map shadows, click on each light source and select
Use Depth Map Shadows in the light’s
Attribute Editor. In the
Render Settings Window, check
Enable Depth Maps.
- In the
Render Settings window, click on the
Maya Software tab and expand the
Render Options section to see the
Lights and Shadows
attributes. Set
Shadow linking
to
Shadows obey shadow linking.
To link selected lights to surfaces using shadow linking (if rendering with Maya Hardware)
- Select the lights and surfaces you want to link.
- In the
Rendering menu set, select
Lighting/shading > Make Shadow Links.
- When rendering with
Maya Hardware, shadow linking must be used in conjunction with depth map shadows. Click on each light source and select
Use Depth Map Shadows
in the light’s
Attribute Editor.
- In the
Render Settings window, click on the
Maya Hardware tab and expand the
Render Options section to see the
Shadow linking
option. Set
Shadow linking to
Shadows obey shadow linking.
To break links between lights and surfaces using shadow linking (if rendering with Maya Software renderer)
- Select the lights and surfaces you want to link.
- In the
Rendering menu set, select
Lighting/shading > Break Shadow Links.
- When rendering with
Maya Software, you may render shadow links via raytraced shadows or depth mapped shadows.
- If you render via raytraced shadows, click on each light source and select
Use Ray Trace Shadows in the light’s
Attribute Editor. In the
Render Settings window, enable
Raytracing.
- If you render via depth map shadows, click on each light source and select
Use Depth Map Shadows in the light’s
Attribute Editor. In the
Render Settings
Window, check
Enable Depth Maps.
- In the
Render Settings window, click on theMaya Software tab and expand the
Render Options section to see the Lights and Shadows
attributes. Set
Shadow linking
to
Shadows obey shadow linking.
