<member name="camera_attributes" type="CameraAttributes" setter="set_camera_attributes" getter="get_camera_attributes">
The [CameraAttributes] resource that specifies exposure levels to bake at. Auto-exposure and non exposure properties will be ignored. Exposure settings should be used to reduce the dynamic range present when baking. If exposure is too high, the [LightmapGI] will have banding artifacts or may have over-exposure artifacts.

<member name="denoiser_strength" type="float" setter="set_denoiser_strength" getter="get_denoiser_strength" default="0.1">
The strength of denoising step applied to the generated lightmaps. Only effective if [member use_denoiser] is [code]true[/code].

<member name="directional" type="bool" setter="set_directional" getter="is_directional" default="false">
If [code]true[/code], bakes lightmaps to contain directional information as spherical harmonics. This results in more realistic lighting appearance, especially with normal mapped materials and for lights that have their direct light baked ([member Light3D.light_bake_mode] set to [constant Light3D.BAKE_STATIC]). The directional information is also used to provide rough reflections for static and dynamic objects. This has a small run-time performance cost as the shader has to perform more work to interpret the direction information from the lightmap. Directional lightmaps also take longer to bake and result in larger file sizes.
[b]Note:[/b] The property's name has no relationship with [DirectionalLight3D]. [member directional] works with all light types.

To further speed up bake times, decrease [member bounces], disable [member use_denoiser] and increase the lightmap texel size on 3D scenes in the Import doc.

<member name="use_denoiser" type="bool" setter="set_use_denoiser" getter="is_using_denoiser" default="true">
If [code]true[/code], uses a CPU-based denoising algorithm on the generated lightmap. This eliminates most noise within the generated lightmap at the cost of longer bake times. File sizes are generally not impacted significantly by the use of a denoiser, although lossless compression may do a better job at compressing a denoised image.
[b]Note:[/b] The built-in denoiser (OpenImageDenoise) may crash when denoising lightmaps in large scenes. If you encounter a crash at the end of lightmap baking, try disabling [member use_denoiser].
