Lighting

When I use iray and set up spotlights and distance lights. Iray never renders those lights I am always just getting a black image. How do I set Iray up to take the lights in? I have the auto headlamp off.

    Did you change the Environment Mode in Render Settings to use scene lights?

    I try that and it still does almost all black. If I render in 3ddelight it will show up like I want it to. But I want to only render in iray.

    Don't use Intensity in Iray, use the Photometric settings and adjust the Luminour Flux.

    Remember that the Tone Mapping group in Render settings is for a bright day outside - for artificial light it will need adjusting.

    For decent looking results you will want gamma correction on (unless you are compositing in another application, in which case you will need to judge the lighting in that).

    Make sure your lights are not being blocked - in Iray all lights cast shadows and all objects block light.
