The parent `_validate_property()` wasn't called, which led to shadow properties being visible even if shadows were disabled on a DirectionalLight3D node.

A directional light is a type of [Light3D] node that models an infinite number of parallel rays covering the entire scene. It is used for lights with strong intensity that are located far away from the scene to model sunlight or moonlight. The worldspace location of the DirectionalLight3D transform (origin) is ignored. Only the basis is used to determine light direction.

<member name="directional_shadow_blend_splits" type="bool" setter="set_blend_splits" getter="is_blend_splits_enabled" default="false">
|
|
If [code]true[/code], shadow detail is sacrificed in exchange for smoother transitions between splits. Enabling shadow blend splitting also has a moderate performance cost. This is ignored when [member directional_shadow_mode] is [constant SHADOW_ORTHOGONAL].

<member name="directional_shadow_fade_start" type="float" setter="set_param" getter="get_param" default="0.8">
|
|
Proportion of [member directional_shadow_max_distance] at which point the shadow starts to fade. At [member directional_shadow_max_distance], the shadow will disappear. The default value is a balance between smooth fading and distant shadow visibility. If the camera moves fast and the [member directional_shadow_max_distance] is low, consider lowering [member directional_shadow_fade_start] below [code]0.8[/code] to make shadow transitions less noticeable. On the other hand, if you tuned [member directional_shadow_max_distance] to cover the entire scene, you can set [member directional_shadow_fade_start] to [code]1.0[/code] to prevent the shadow from fading in the distance (it will suddenly cut off instead).

<member name="directional_shadow_max_distance" type="float" setter="set_param" getter="get_param" default="100.0">
|
|
The maximum distance for shadow splits. Increasing this value will make directional shadows visible from further away, at the cost of lower overall shadow detail and performance (since more objects need to be included in the directional shadow rendering).

<member name="directional_shadow_pancake_size" type="float" setter="set_param" getter="get_param" default="20.0">
|
|
Sets the size of the directional shadow pancake. The pancake offsets the start of the shadow's camera frustum to provide a higher effective depth resolution for the shadow. However, a high pancake size can cause artifacts in the shadows of large objects that are close to the edge of the frustum. Reducing the pancake size can help. Setting the size to [code]0[/code] turns off the pancaking effect.

<member name="directional_shadow_split_1" type="float" setter="set_param" getter="get_param" default="0.1">

The distance from camera to shadow split 1. Relative to [member directional_shadow_max_distance]. Only used when [member directional_shadow_mode] is [constant SHADOW_PARALLEL_2_SPLITS] or [constant SHADOW_PARALLEL_4_SPLITS].

The distance from shadow split 1 to split 2. Relative to [member directional_shadow_max_distance]. Only used when [member directional_shadow_mode] is [constant SHADOW_PARALLEL_4_SPLITS].

If [code]true[/code], this [DirectionalLight3D] will not be used for anything except sky shaders. Use this for lights that impact your sky shader that you may want to hide from affecting the rest of the scene. For example, you may want to enable this when the sun in your sky shader falls below the horizon.

<constant name="SHADOW_ORTHOGONAL" value="0" enum="ShadowMode">
|
|
Renders the entire scene's shadow map from an orthogonal point of view. This is the fastest directional shadow mode. May result in blurrier shadows on close objects.
|
|
</constant>
|
|
<constant name="SHADOW_PARALLEL_2_SPLITS" value="1" enum="ShadowMode">
|
|
Splits the view frustum in 2 areas, each with its own shadow map. This shadow mode is a compromise between [constant SHADOW_ORTHOGONAL] and [constant SHADOW_PARALLEL_4_SPLITS] in terms of performance.
|
|
</constant>
|
|
<constant name="SHADOW_PARALLEL_4_SPLITS" value="2" enum="ShadowMode">
|
|
Splits the view frustum in 4 areas, each with its own shadow map. This is the slowest directional shadow mode.
