Quality setting for shadows cast by [DirectionalLight3D]s. Higher quality settings use more samples when reading from shadow maps and are thus slower. Low quality settings may result in shadows looking grainy.
[b]Note:[/b] The Soft Very Low setting will automatically multiply [i]constant[/i] shadow blur by 0.75x to reduce the amount of noise visible. This automatic blur change only affects the constant blur factor defined in [member Light3D.shadow_blur], not the variable blur performed by [DirectionalLight3D]s' [member Light3D.light_angular_distance].
[b]Note:[/b] The Soft High and Soft Ultra settings will automatically multiply [i]constant[/i] shadow blur by 1.5× and 2× respectively to make better use of the increased sample count. This increased blur also improves stability of dynamic object shadows.

Use 4 splits for shadow projection when using directional light.

<constant name="SHADOW_QUALITY_HARD" value="0" enum="ShadowQuality">
Lowest shadow filtering quality (fastest). Soft shadows are not available with this quality setting, which means the [member Light3D.shadow_blur] property is ignored if [member Light3D.light_size] and [member Light3D.light_angular_distance] is [code]0.0[/code].
[b]Note:[/b] The variable shadow blur performed by [member Light3D.light_size] and [member Light3D.light_angular_distance] is still effective when using hard shadow filtering. In this case, [member Light3D.shadow_blur] [i]is[/i] taken into account. However, the results will not be blurred, instead the blur amount is treated as a maximum radius for the penumbra.
