I'm quite new to Daz and am trying out tutorials. At the moment I'm having trouble with emissive objects as show in this video :

(at 20:53)

I've done everything exactly like this and my emissive plane won't light up my character.
Here's some pics :

Please help !

    Where is your plane? Try using the top/front/left views to make sure it is correctly placed to light the figure.

    Edit : It works now (only after reload). It renders correctly but the preview window is still dark. Any ideas ?

    Emissive lights aren't shown in the viewport. However, you can at least get enough light by turning off the Preview Lights option in the Window menu. Keyboard shortcut is Ctrl-L for Windows based PCs.

    I finally git it to work (kind of). It seems to render correctly. However the preview (camera + nvidia iray) still comes out black.

    It will be. Because the preview engine doesn't have everything that the full rendering engine does. The best you can do is use Ctrl-L to turn off the lighting preview so that at least you can see your scene well enough to pose your figure, etc.

    The Iray preview mode will show emissive lighting if it is set to Photoreal in the Draw Settings pane

    Thanks for your help. Ctrl-L was very helpful but not quite what I'm looking for.

    Watch the video I posted at 24:05. His preview window shows how the emissive lighting changes in real time, as he fiddles with the luminus efficacy and emission temperature. If he can do it, why can't I ? :)

    I find photoreal in render settings, but not in draw settings.

    You need to select Drawstyle : Nvidia Iray, then go to Drawing, Draw Mode, drop down and select Photoreal.
