Hi there ^^
I am trying to render a scene which includes an unimesh figure sitting ona  desert island near a campfire. Since all there is around is the sea and the sky, no real decorum problem there... except that I don't want the yellowish light of my fire to turn my skydome yellow. How can I make it so the skydome does not react to this specific set of lights?
Thanks in advance, I am clueless here.

If the fire is an actual light, you could make it a point light and set its
Dist Start and Dist End so that the light fades just beyond the figures...
 
If it's an ambient, I don't know!

actually they're spots. I purchased the "ultimate" fire kit from romanceworks today :-)

If spots, then you can do a similar thing - just set the distance start to a point beyond the figure, but before the skydome. To help matters, it might be worth scaling up the skydome as well to give you more room to play with.

thanks for the tips :) I'll try that in the morning :D
These fire effects are nice, too... just a bit to fiery :p

Sky domes give off their own light. You should not plug your sky color map into Diffuse_Color. Set DIffuse_Value = 0, Specular_Value = 0, and plug the color map straight into Alternate_Diffuse.

The sky will now have NO reaction to light of any kind. Even if you delete all your lights, it will still be there.
