How to turn off ALL lights?

I am using 3delight render engine for this.
I know under Edit--Delete---Delete all lights. But there is a light in my scene that is completely ruining the render with its harsh glare and massive shadow effect. But I have all lights gone in the scene, it should render black but it does not. There appears to be a light in the floor that is acting like a spot light and for the life of me I can't find it and turn the stinking thing off. I can't light the scene properly with this crappy light lit up, I want to create a night time render, but towards the bottom the scene is lit up like an enormous spot light is on, creating super bright light on the right and ugly thick shadows on the props next to the figure. I've gone through and deleted anything with the word 'light' in the Scenes tab and that light is still there. There are no lights to delete....this is driving me crazy!!

Have you tried turning off the headlamp that its attached to the camera.
Alternately, it may be ambient light which can sometimes be masked by adding a light, weird but true,
Yeah, all headlamps are off.
When I add the lights that are attached to the props, that harsh light stays there. I've tried adding points, distant and it still shows up. I added a sphere to the scene as a marker and moved the figure back, there is a light under the sphere. I thought maybe there was something in the prop set I was using so I moved it far back, but the light is still there.
Do not rely on the name of an item in the scene tab to determine if it is a light or not, a light could be named anything. Better is to open the "Lights" tab, and all the lights should be listed there.
The headlamp won't stay off when reandering when there are no lights in the scene. Best to keep one light in the scene and turn that light off, that way the headlamp will stay off.
Oh you can use the Select > Select all Lights command from the scene pane Options box in the top corner of the pane
Only when it's set to "Auto". If you set it to "Off" it stays off.
Even with 3DL now? I must admit I haven't used 3DL since Iray came out.
Stupid question ... is a surface set to be an emitter (in 3Delight maybe an omAreaLight?) or simply the Ambient is so bright it glows?
Szark--I tried setting up a single light, all headlamps are off but that glare-light is still present. :(
All headlamps are off. There are no lights showing up under the light tab.
I have several camera angles set up, all headlamps on those are off. When I see the scene through those cameras, everything is black. But renders with that glaring light. If I select perspective view, the scene lights up in shaded texture mode.
Kerya--I didn't see anything that resembled omAreaLight, but it could be using a different name? I looked for "emit" and saw nothing. Ambient is set to off as I thought maybe the walls of the prop had something.
I'm at a loss and I don't know enough about DS to dig around in other locations. Here is what renders. Even if I add a light to this, that glare light stays and makes nasty shadows.
Edit: I am rebuilding the scene. I loaded the prop first and it renders black because there are no lights. So my glary light is not from the prop. I merged in the saved figure I was using and the light source is coming off the figure. Now I'm in the process of elmination on what item of clothing this damn light is attached to...or quite possibly, on the figure itself.
When I load the figure, I'm getting Area Light-Headlamp blocker showing up in the parameters tab.
2nd edit: There appears to be something attached to the figure. I deleted all clothing items off 1 at a time and was still getting the same effect. Right down to the bday suit and still got the light, it appears to be behind the feet. So I thought maybe it's part of the skin texture, so I hid the figure and the image rendered black. I brought in a new figure plain vic out of the box, rendered and everything is black. I added the same texture and it rendered black, so now I'm looking at something was attached to the clothing item that has attached itself to the scene and I'll be damned what it is...a bug by the looks of it and now I'm off to add same items to the new vic and see what it is!
If it is coming off the figure, perhaps you had the figure or clothing selected when you added a light and it parented under it. So I am assuming you know how to open up each part of the figure in Scene and look at the sub-sections under each part of the body to see if the light is there. (Not trying to be insulting, I don't know what you know.)
You can also go to the viewport and in the different views, see what lights are your options there. I found one really quickly doing it that way, instead of using Scene or other options. I did that because it's so easy to see where the light(s) are actually shining.
Novica, you're fine, not insulting :)
The headlamp blocker thing kept coming back into my scene even after deleting it. I added a single point light, and sent it off to bfe and I could delete the headlamp-block thing but I was still getting the funky light.
There are no lights on except the point light and this way off on the left pointing into space.
In the image, the figure is tucked away in one of those alcoves...and see the light is still there. That little light on the floor is responsible for lighting up that whole area.
Edit: I kind of fixed it. There was something on the skin texture causing this. I changed skin textures, rendered and everything went black. I reapplied the old texture and it still rendered black, so there was something applied to the skin at some point of building or I might have been using different skins to find something. I know I used Zevo skin builder thing and that might have added something since it's a script. But I went with a different skin texture after using that script and I was getting that light issue. So it really can't be the script. But for now, everything is black! *throws confetti up in the air in wild abandoment* Holy cow I spent days on this problem.
Oh good! At least you figured it out. I feel your pain. I spent four and a half hours one day on a product that as it turns out, was defective. When I added a bow to the shoe, the other bow would shoot out into space. (Seriously!) I was a newbie so thought something that obvious couldn't possibly have gotten by the quality control people. Now, I never waste hours again on anything that is really funky because the forum members are so helpful and experienced, they will probably know something about most topics, and what I'm doing wrong (if I am.)
But I have to admit I'm stumped as to how a skin texture can be emitting light. Is that what you're saying happened?
It was pretty common in the V4 days to add a color to the ambient channel. When those are converted to Iray, the Ambient channel settings are usually translated to the Emissive node. Any color other than full black will trigger light emission, even if it's at a fairly low luminance value.
Hopefully, no vendors these days are "lighting up" their 3DL or Poser textures by monkeying with the Ambient channel. But that doesn't mean we don't have scores of these material settings from old products to deal with when converting to Iray.
Ooh, thanks Tobor! So if there's emission that is wonky, look to the Ambient channel as a possible culprit. Good to know!
I don't know if or what it is worth but my lighting issue was using 3dlight renderer, lol I didn't even attempt Iray on that set up. I have another headache going on in Iray dealing with another lighting issue, but it's the other way around, I can't get it to light up at all. I'm playing with a dark custom made skin and I've loaded the area with lights, but the damn thing is still dark and everything else is just about over exposed with lights. I know one thing, I can get myself into the damnest places/situations with these programs.
