Do I need an updated LuxBlend25 for the new Blender 2.58?
Until now, I just have copied my previous luxrender-folder out of
<BlenderHome>/2.57/scripts/addons/
into
<BlenderHome>/2.58/scripts/addons/
(same with the presets folder).
Now I have a weird bug: I can only see one lightgroup in the world-tab, when I add more lgs, I can't see or rename them, but for the lamps they are visible (as "New Lightgroup", "New Lightgroup", "New Lightgroup" etc.).
