### Remarks

Default value: set, if your project uses the Scriptable Render Pipeline.

If your project uses the Built-in Render Pipeline, this value is unset if [QualitySettings.shadows](/engine/6000.6/script-reference/unityengine/qualitysettings/shadows.md) is set to [ShadowQuality.Disable](/engine/6000.6/script-reference/unityengine/shadowquality/disable.md); otherwise, it is set. Note that changing this value has no effect in the Built-in Render Pipeline.
