Unity beast lightmap baking - bake some new objects without losing existing lightmaps from previously baked result

As titled ,

  • Is this currently doable?
  • Is this kind function likely be there in the final build of U3?
  • Any suggestion of workarounds?

Many thanks

I cant answer all of your questions as of now but have a look at the below link.It lets you save the current state of your lightmap and reuse it later.
