VoxelGI

public VoxelGI();

Creates a VoxelGI without Data, with Size = (20, 20, 20) and Subdiv128. Add it to the level tree, prepare geometry and bake or assign existing data. A supported Forward+ renderer is needed for visual output.

public CameraAttributes CameraAttributes { get; set; }

Attributes used for bake exposure normalization, not the active camera or its Environment. Physical lighting uses CameraAttributes normalization; assignment also updates normalization for existing Data. Keep bake settings consistent with the exposure in use.

public VoxelGIData Data { get; set; }

Prepared volume data. Without Data the VoxelGI supplies no indirect light. Assignment neither bakes nor copies the resource; null clears the assigned data. Account for resource sharing between independent volumes.

public Vector3 Size { get; set; }

Full box size on each axis, not half-extents. Local bounds run from −Size/2 to +Size/2. Setting clamps each component to at least 1. Rebake Data after changing it; old data is not automatically rebuilt.

public VoxelGI.SubdivEnum Subdiv { get; set; }

Longest-axis detail: Subdiv64, Subdiv128, Subdiv256 or Subdiv512; defaults to Subdiv128. Shorter axes adjust accordingly. Changing this does not rebake Data; higher detail needs more work and memory. Supply a valid enum value.

public void Bake(Entity fromNode = null, bool createVisualDebug = false);

Synchronously prepares visible static geometry from fromNode and descendants within the volume. With null, the root is the VoxelGI parent, which must exist. With createVisualDebug = false creates or updates Data. An assigned resource may be modified rather than replaced. Returns void: inspect errors and results; old nonnull Data alone does not prove a new bake succeeded. Saving the level does not replace saving external Data as .rbin.

public void DebugBake();

Runs Bake with null and createVisualDebug = true, creating a child MultiMeshInstance3D to inspect voxelization instead of producing ordinary Data. This is an editor diagnostic method, not persistence of usable GI.

public CameraAttributes GetCameraAttributes();

Returns the current CameraAttributes. Attributes used for bake exposure normalization, not the active camera or its Environment. Physical lighting uses CameraAttributes normalization; assignment also updates normalization for existing Data. Keep bake settings consistent with the exposure in use.

public VoxelGIData GetProbeData();

Returns the current Data. Prepared volume data. Without Data the VoxelGI supplies no indirect light. Assignment neither bakes nor copies the resource; null clears the assigned data. Account for resource sharing between independent volumes.

public Vector3 GetSize();

Returns the current Size. Full box size on each axis, not half-extents. Local bounds run from −Size/2 to +Size/2. Setting clamps each component to at least 1. Rebake Data after changing it; old data is not automatically rebuilt.

public VoxelGI.SubdivEnum GetSubdiv();

Returns the current Subdiv. Longest-axis detail: Subdiv64, Subdiv128, Subdiv256 or Subdiv512; defaults to Subdiv128. Shorter axes adjust accordingly. Changing this does not rebake Data; higher detail needs more work and memory. Supply a valid enum value.

public void SetCameraAttributes(CameraAttributes cameraAttributes);

Sets CameraAttributes. Attributes used for bake exposure normalization, not the active camera or its Environment. Physical lighting uses CameraAttributes normalization; assignment also updates normalization for existing Data. Keep bake settings consistent with the exposure in use.

public void SetProbeData(VoxelGIData data);

Sets Data. Prepared volume data. Without Data the VoxelGI supplies no indirect light. Assignment neither bakes nor copies the resource; null clears the assigned data. Account for resource sharing between independent volumes.

public void SetSize(Vector3 size);

Sets Size. Full box size on each axis, not half-extents. Local bounds run from −Size/2 to +Size/2. Setting clamps each component to at least 1. Rebake Data after changing it; old data is not automatically rebuilt.

public void SetSubdiv(VoxelGI.SubdivEnum subdiv);

Sets Subdiv. Longest-axis detail: Subdiv64, Subdiv128, Subdiv256 or Subdiv512; defaults to Subdiv128. Shorter axes adjust accordingly. Changing this does not rebake Data; higher detail needs more work and memory. Supply a valid enum value.
