<member name="quality" type="int" setter="set_bake_quality" getter="get_bake_quality" enum="BakedLightmap.BakeQuality" default="1">
Determines the amount of samples per texel used in indrect light baking. The amount of samples for each quality level can be configured in the project settings.

<member name="use_color" type="bool" setter="set_use_color" getter="is_using_color" default="true">
Store full color values in the lightmap textures. When disabled, lightmap textures will store a single brightness channel. Can be disabled to reduce disk usage if the scene contains only white lights or you don't mind losing color information in indirect lighting.
</member>
<member name="use_denoiser" type="bool" setter="set_use_denoiser" getter="is_using_denoiser" default="true">
When enabled, a lightmap denoiser will be used to reduce the noise inherent to Monte Carlo based global illumination.
</member>
<member name="use_hdr" type="bool" setter="set_use_hdr" getter="is_using_hdr" default="true">
Store the lightmap textures in a Hight Dynamic Range format (EXR). Can be disabled to reduce disk usage, but light values over 1.0 will be clamped and you may see banding caused by the reduced precision.
