Enumerations

enum LightmapScale:

• LIGHTMAP_SCALE_1X = 0 --- The generated lightmap texture will have the original size.
• LIGHTMAP_SCALE_2X = 1 --- The generated lightmap texture will be twice as large, on each axis.
• LIGHTMAP_SCALE_4X = 2 --- The generated lightmap texture will be 4 times as large, on each axis.
• LIGHTMAP_SCALE_8X = 3 --- The generated lightmap texture will be 8 times as large, on each axis.
• LIGHTMAP_SCALE_MAX = 4

enum ShadowCastingSetting:

• SHADOW_CASTING_SETTING_OFF = 0 --- Will not cast any shadows.
• SHADOW_CASTING_SETTING_ON = 1 --- Will cast shadows from all visible faces in the GeometryInstance.

Will take culling into account, so faces not being rendered will not be taken into account when shadow casting.

• SHADOW_CASTING_SETTING_DOUBLE_SIDED = 2 --- Will cast shadows from all visible faces in the GeometryInstance.

Will not take culling into account, so all faces will be taken into account when shadow casting.

• SHADOW_CASTING_SETTING_SHADOWS_ONLY = 3 --- Will only show the shadows casted from this object.

In other words, the actual mesh will not be visible, only the shadows casted from the mesh will be.

enum Flags:

• FLAG_USE_BAKED_LIGHT = 0 --- Will allow the GeometryInstance to be used when baking lights using a GIProbe or BakedLightmap.
• FLAG_DRAW_NEXT_FRAME_IF_VISIBLE = 1 --- Unused in this class, exposed for consistency with InstanceFlags.
• FLAG_MAX = 2 --- Represents the size of the Flags enum.

Property Descriptions

ShadowCastingSetting cast_shadow

Default	1
Setter	set_cast_shadows_setting(value)
Getter	get_cast_shadows_setting()

The selected shadow casting flag. See ShadowCastingSetting for possible values.

float extra_cull_margin

Default	0.0
Setter	set_extra_cull_margin(value)
Getter	get_extra_cull_margin()

The extra distance added to the GeometryInstance's bounding box (AABB) to increase its cull box.

bool generate_lightmap

Default	true
Setter	set_generate_lightmap(value)
Getter	get_generate_lightmap()

When disabled, the mesh will be taken into account when computing indirect lighting, but the resulting lightmap will not be saved. Useful for emissive only materials or shadow casters.

LightmapScale lightmap_scale

Default	0
Setter	set_lightmap_scale(value)
Getter	get_lightmap_scale()

Scale factor for the generated baked lightmap. Useful for adding detail to certain mesh instances.

float lod_max_distance

Default	0.0
Setter	set_lod_max_distance(value)
Getter	get_lod_max_distance()

The GeometryInstance's max LOD distance.

Note: This property currently has no effect.

float lod_max_hysteresis

Default	0.0
Setter	set_lod_max_hysteresis(value)
Getter	get_lod_max_hysteresis()

The GeometryInstance's max LOD margin.

Note: This property currently has no effect.

float lod_min_distance

Default	0.0
Setter	set_lod_min_distance(value)
Getter	get_lod_min_distance()

The GeometryInstance's min LOD distance.

Note: This property currently has no effect.

float lod_min_hysteresis

Default	0.0
Setter	set_lod_min_hysteresis(value)
Getter	get_lod_min_hysteresis()

The GeometryInstance's min LOD margin.

Note: This property currently has no effect.

Material material_override

Setter	set_material_override(value)
Getter	get_material_override()

The material override for the whole geometry.

If a material is assigned to this property, it will be used instead of any material set in any material slot of the mesh.

bool use_in_baked_light

Default	false
Setter	set_flag(value)
Getter	get_flag()

If true, this GeometryInstance will be used when baking lights using a GIProbe or BakedLightmap.

Method Descriptions

bool get_flag ( Flags flag ) const

Returns the Flags that have been set for this object.

void set_custom_aabb ( AABB aabb )

Overrides the bounding box of this node with a custom one. To remove it, set an AABB with all fields set to zero.

void set_flag ( Flags flag, bool value )

Sets the Flags specified. See Flags for options.
