BakedLightmap¶

Category: Core
Brief Description¶
Prerendered indirect light map for a scene.
Properties¶
Enumerations¶
enum BakeQuality:
- BAKE_QUALITY_LOW = 0 — Lowest bake quality mode. Fastest to calculate.
- BAKE_QUALITY_MEDIUM = 1 — Default bake quality mode.
- BAKE_QUALITY_HIGH = 2 — Highest bake quality mode. Takes longer to calculate.
enum BakeMode:
- BAKE_MODE_CONE_TRACE = 0 — Less precise but faster bake mode.
- BAKE_MODE_RAY_TRACE = 1 — More precise bake mode but can take considerably longer to bake.
enum BakeError:
- BAKE_ERROR_OK = 0
- BAKE_ERROR_NO_SAVE_PATH = 1
- BAKE_ERROR_NO_MESHES = 2
- BAKE_ERROR_CANT_CREATE_IMAGE = 3
- BAKE_ERROR_USER_ABORTED = 4
Description¶
Baked lightmaps are an alternative workflow for adding indirect (or baked) lighting to a scene. Unlike the GIProbe approach, baked lightmaps work fine on low-end PCs and mobile devices as they consume almost no resources in run-time.

Property Descriptions¶
- float bake_cell_size
Setter | set_bake_cell_size(value) |
Getter | get_bake_cell_size() |
Grid subdivision size for lightmapper calculation. Default value of 0.25
will work for most cases. Increase for better lighting on small details or if your scene is very large.
- float bake_energy
Setter | set_energy(value) |
Getter | get_energy() |
Multiplies the light sources’ intensity by this value. For instance, if the value is set to 2, lights will be twice as bright. If the value is set to 0.5, lights will be half as bright.
- Vector3 bake_extents
Setter | set_extents(value) |
Getter | get_extents() |
- bool bake_hdr
Setter | set_hdr(value) |
Getter | is_hdr() |
If true
, lightmap can capture light values greater than 1.0
. Turning this off will result in a smaller lightmap. Default value:false
.
- BakeMode bake_mode
Setter | set_bake_mode(value) |
Getter | get_bake_mode() |
Lightmapping mode. See BakeMode.
- float bake_propagation
Setter | set_propagation(value) |
Getter | get_propagation() |
Defines how far the light will travel before it is no longer effective. The higher the number, the farther the light will travel. For instance, if the value is set to 2, the light will go twice as far. If the value is set to 0.5, the light will only go half as far.
- BakeQuality bake_quality
Setter | set_bake_quality(value) |
Getter | get_bake_quality() |
Three quality modes are available. Higher quality requires more rendering time. See BakeQuality.
- float capture_cell_size
Setter | set_capture_cell_size(value) |
Getter | get_capture_cell_size() |
Grid size used for real-time capture information on dynamic objects. Cannot be larger than bake_cell_size.
- String image_path
Setter | set_image_path(value) |
Getter | get_image_path() |
Location where lightmaps will be saved.
- BakedLightmapData light_data
Setter | set_light_data(value) |
Getter | get_light_data() |
The calculated light data.
