Lightning "Groups" to prevent overlapping


I need to switch the display of meshs at runtime, they sits on the same place but would never overlap, because of the switch.

How can I bake lightning on them without having overlapped lightning ?

Cheers !


Separate your different meshes into sublevels. Keep your lights, and any mesh that wont change in the persistent level. Unhide one sublevel at a time and build lighting for it. Hide that sublevel and then unhide the other and then build lighting for that one. Then you can either stream them in and out as needed at run time, or just have them always loaded, and hide/unhide them the way you were originally doing so. That should work I believe.
