When enabled, a lightmap denoiser will be used to reduce the noise inherent to Monte Carlo based global illumination.

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.
If [code]true[/code], stores the lightmap textures in a high dynamic range format (EXR). If [code]false[/code], stores the lightmap texture in a low dynamic range PNG image. This can be set to [code]false[/code] to reduce disk usage, but light values over 1.0 will be clamped and you may see banding caused by the reduced precision.
[b]Note:[/b] Setting [member use_hdr] to [code]true[/code] will decrease lightmap banding even when using the GLES2 backend or if [member ProjectSettings.rendering/quality/depth/hdr] is [code]false[/code].
