the current lightmap functionality allows to bake soft shadows and ambient occlusion, which is nice. But it would be much cooler if it would bake indirect lighting as well. Also, I believe it would be nice to prepare light maps offline in the editor, not every time the game is starting.
It would be nice for sure, but it’s unfortunately not on a TODO list for the near future. The lightmapping was designed as a system where lightmap baking can be done when the application starts, to avoid downloading large lightmaps. This puts hard constraints on performance, and so on the quality as well.
Adding baking in the Editor would likely be a completely independent functionality.
