BakedLightmapUseHdr Property

If true, stores the lightmap textures in a high dynamic range format (EXR). If false, stores the lightmap texture in a low dynamic range PNG image. This can be set to false to reduce disk usage, but light values over 1.0 will be clamped and you may see banding caused by the reduced precision.

Note: Setting UseHdr to true will decrease lightmap banding even when using the GLES2 backend or if is false.
