Hi there
Suppose I have a bunch of lamps all placed exactly where I want them, but they’re too bright, or the wrong color, etc. Is it possible to select all by type, and then do a mass change or is it a one-at-a-time thing? I’ve tried selecting all and changing one, hoping that would do it, but it only changed that particular one.
Discuss.

You can link lamp data from one lamp to the others by going to the object meny >> make links >> lamp data.
The problem with this is, that this also effects the energy of the lighting, shadow settings etc…
Which is probably not what you want. And I fear there is no other solution, I can’t think of a way to change one setting for many lamps simultaneously without linking them.
Fortunately, for this particular exercise, it’s a viable option. Next time, though, more attention to detail!
