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.
