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.

+ 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.
+
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.
