Sounds normal, rooster, but do they work when you render the scene? I think it has limitations such as only 8 lights will show anyway. After that, they don't appear to work until you render the scene, and possibly it's a memory saving option because maya figures you'll have way more than 8 instanced lights. Anyway, my old…
ah, no its not the viewport display. Max also has that 8-light limit, or is it the video card? (I think software rendering displays all lights in viewport) anyway, no I mean I duplicate a light, and it renders, but if I do it with instancing turned on, nada. Maya 6 bug?
