BakeLighting Class
Warning
The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScript (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.
This class allows you to bake lighting.
Warning
Backward compatibility for this class is not guaranteed! Although it is exposed to public API, it is mainly intended for internal use (inside UnigineEditor). If you use it, you do this at your own risk.

void bake ( Vector<LightVoxelProbe> voxel_lights, Vector<LightEnvironmentProbe> env_lights, Vector<Light> shadow_lights, Vector<ObjectMeshStatic> objects, Vector<int> surfaces ) #
Starts the process of light baking for all voxel and environment probes, shadow baking for light sources in static light mode and lightmaps baking for surfaces of Mesh Static objects in the given list.Arguments
- Vector<LightVoxelProbe> voxel_lights - List of voxel probes for which the process of light baking is to be performed. The order of nodes added for baking is not important.
- Vector<LightEnvironmentProbe> env_lights - List of environment probes for which the process of light baking is to be performed. The order of nodes added for baking is not important.
- Vector<Light> shadow_lights - List of light sources in static light mode for which the process of shadow baking is to be performed. The order of lights added for baking is not important.
- Vector<ObjectMeshStatic> objects - List of Mesh Static objects for which the process of lightmaps baking is to be performed.
- Vector<int> surfaces - List of surfaces of Mesh Static objects for which the process of lightmaps baking is to be performed.
NoticeThe number of objects and surfaces added for baking must be equal.
void bakeAll ( int voxel_probes = true, int env_probes = true, int shadow = true, int lightmap = true ) #

- int lightmap - 1 to enable lightmaps baking for surfaces of Mesh Static objects; otherwise, 0.
int isBaking ( ) #
Returns a value indicating if the process of baking is being performed at the moment.Return value
1 if lighting is being baked; otherwise - 0.int getCurrentBounce ( ) #
Returns a bounce being calculated at the moment.Notice
If the process of baking is not being performed at the moment, 1 is returned.
Return value
Bounce number.int getBounces ( ) #
Console: bake_lighting_bounces
Returns number of all bounces.Return value
Number of bounces.int getProgress ( ) #
Returns overall progress of light baking.Notice
If the process of baking is not being performed at the moment, 0 is returned.
Return value

Console: bake_lighting_voxel_size_multiplier
Sets the value of the voxel size multiplier parameter.Arguments
- float multiplier - Voxel size multiplier within the [0.0f, 8.0f] range. The default value is 1.
void stop ( int save_results = false ) #
Console: bake_lighting_stop
Interrupts the process of light baking, if it is in performing state.Arguments
- int save_results - 1 to save the obtained result; 0 to restore the previous content.
Light getCurrentLight ( ) #
Returns an instance of the LightVoxelProbe being calculated at the moment.Return value
Current LightVoxelProbe.void addReadOnlyTexture ( UGUID guid ) #
Adds a read-only texture with the specified GUID.Arguments
- UGUID guid - GUID of the read-only texture to be added.
void removeReadOnlyTexture ( UGUID guid ) #
Removes the read-only texture with the specified GUID.Arguments
- UGUID guid - GUID of the read-only texture to be removed.
void setSamplesPerFrame ( int frame ) #
Console: bake_lighting_samples_per_frame
Sets number of voxels for voxel probes and samples for environment probes, light sources and surfaces computed and visualized per single frame.Arguments
- int frame - Number of samples per frame within the [1, 500] range. The default value is 1.
NoticeHigh values cause longer user interface response.
int getSamplesPerFrame ( ) #
Returns number of voxels for voxel probes and samples for environment probes, light sources and surfaces computed and visualized per single frame.Return value
Number of samples.void setLightmapQuality ( int quality ) #
Console: bake_lightmap_quality
Sets the global baking quality for lightmaps.Arguments
- int quality - One of LIGHTMAP_QUALITY values.
int getLightmapQuality ( ) #
Console: bake_lightmap_quality
Returns the current global baking quality for lightmaps.Return value
LIGHTMAP_QUALITY preset.void setLightmapViewportMask ( int mask ) #
Console: bake_lightmap_viewport_mask
Sets the viewport mask for the lightmapper. For a light or surface to contribute to static GI, their viewport masks should match the baking viewport mask.Arguments
- int mask - Viewport mask (integer, each bit of which is used to represent a mask).
int getLightmapViewportMask ( ) #
Returns the current viewport mask set for lightmapper.Return value
Viewport mask (integer, each bit of which is used to represent a mask).void setLightmapZFar ( float zfar ) #
