In Unity 5 beta (Pro), while processing existing 4.6 scene for 5 I get the Lightmapper message (warning) that my lightmaps are generated in the wrong color space (gamma). In Player settings I have linear color space selected and my camera is using Player Settings. Docs say Lightmapper will detect this condition (which it does) and automatically correct it (which it does not). I am also using Lightmapper Extended, which I suspect may not fully support 5’s new API (yet).
Any suggestions?
When you are using linear lighting,
all lighting and textures are
linearized, which means that the
values passed to the lightmapper also
need to be modified. When you switch
between linear lighting and gamma
lighting, you will need to rebake
lightmaps. The Unity lightmapping
interface will warn you when the
lightmaps are in the wrong color
space.
This is the current documentation. I’m not sure if it is valid for Unity 5, but currently when you switch color space, you need to rebake lightmaps.
I think he did that. The same issue is occuring for me as well. I still shows, that the color space is wrong – even after restarting Unity AND rebaking.
