Simple Q about lighting background

I am doing a image where the room is pretty dark but there is a fire in the background. For the fire I have gotten a normal plane primitive and put a fire image on it. As soon as I apply the dark lights the entire room is dark (yes I will worry about some other lighting to make the image viewable) but the fire on the plane primitive is totally dark. Is there a simple way of lighting up the primitive surface? I would assume its one of the surface options for it.

    You are using Iray? Make the surface with the fire emissive (press [ctrl] while applying and select ignore in the popup menue to keep the fire surface)

    If you are redering in 3delight look at this thread: http://www.daz3d.com/forums/discussion/151046/panel-lights-in-3delight#latest the general system is the same.

    Not sure what you mean with dark lights though.

    Oh sorry I am using Iray. I have no idea what you meant by making it emissive. Is this an option in the surfaces?! what I meant with the dark lighting was I am trying to do an overall dark low lighting atmosphere as the scene is taking part in a dungeon so obviously with this I need to make the fire background be visible.

    Yes, Emission is one of the options in the Surface tab.  Select your plane.  If you haven't already, hit the plane with the Iray Uber Shader to get the Iray surfaces.  Primitives are created with 3DL surfaces by default.  You need to apply the Iray Uber Shader in order to get the Iray surfaces options.  Once you've done that, open the tree of surface options.  Emission is the second to the last option.  Click on it and you'll see black as the emission color.  Click on the emission color and select white to turn on emissions.  You'll now have some more options.  Put the flame picture that you put on your plane into the emission channel by clicking on the box with the triangle next to Emission color.  Your emission channel will now use the colors of your image to help light the plane.  You'll still have to play with the Luminance settings to get it to the desired brightness level.

    As knittingmonny says.

    Check out this thread, it deals with emissive, and might help you a bit finding stuff. http://www.daz3d.com/forums/discussion/110771/natural-iray-lighning-for-rooms#latest
