For
more information about depth map shadows, see
Depth map shadows.
To create a depth map shadow
- Select the light for which you want to
produce a shadow.
- In
the Shadows section of the light’s Attribute Editor,
turn on Use Depth Map Shadows.
- Select the surface on which you want
to cast a shadow.
- In the Render Stats section
of the surface’s Attribute Editor, turn on Casts Shadows.
Tip
- Set the light’s Resolution in
Depth Map Shadow Attributes to the lowest value that produces shadows
of acceptable quality. As a starting point, set Dmap
Resolution to the same value as the rendering resolution.
If Dmap Resolution is too low,
shadow edges appear jagged. If Dmap Resolution is too
high, rendering times increase.
- When batch rendering from the command
line, generate shadow depth maps before rendering the scene by using
the Render -sp <sceneName> command
and option. This can help reduce rendering times and you can reuse
the depth maps for subsequent renders.
