Iray: Christmas lights only red is working

Posts: 2,674
I have a christmas tree in a scene. It has lights.
It was a freebie somewhere...I did a conversion to iray.
The lights have Red, Blue, Green, Purple, Orange bulbs. (pic 1)
Each has the same emissive setting, (pic 2). Temp=450 Lum=10000
However, only the Red shows up. (pic 3) Actually, looking, those are not the red lamps, rather different color ones getting lit red.
Can anyone give me any hints as to how to get this working?

Set temperature to 6500, for starters. Do all the lights of the same color have different groups then the other colors? Which freebie? Give a bit more info ...
Changing the temperature to 6500 seems to have helped. I'll have to learn what that is at some point. Thanks for that info!
I don't know what you mean by groups.
I was wrong on the freebie..it's the yulide treasures 2011 here.
The light temperature varies from below 6500 as 'cold' (blueish) and above 6500 as warm (orange/red), 6500 appears to be neutral.
Huh... the 450 was a default I think, or a setting I coppied...weird.
That should be reversed 6500K really white, 5500K Daylight and 4000K getting down to orange with 150K really red. You can also change the Kelvin scale to 0 and just use the colour bar for the light colour.
I take a different approach to "light" bulbs. This string of lights, from the Yuletide Treasure Tree 2011 has 5 bulb material zones. After applying the Iray Emissive shader to the 5 bulbs, for each of the 5 bulb material zones, changed Emission Color from white to a color and changed the Luminance from 50000 to 5000000.
That's basically what I did (hit it with the iray uber shader, then changed the emission colors to the bulbs color). I just had the settings wrong from whatever I copied them from (or typoed maybe).
I have this tree, too. Thanks to this thread, I did some experimenting with the lights. I was unable to get satisfactory light colors just using the Emission Temperature (K) and had added the same color value from the Base Color to the Emission Color. I came back here and refreshed the thread and saw Szark's comment. So I tried setting the temperature to 0 and just applying the color to the Emission Color and that worked like a charm. (Thanks, Szark!)
Images with a lot of emissive surfaces take a long time to render, especially in CPU Only mode. This image is at about 3.5% after 7+ hours. Very grainy because it's so dark. But I thought I'd share it here anyway...
Ah..that's good to know!
