Why does my render job only render text in the foreground of an image and ignores my figures, textures and the entire background of the image? It renders it black. You can see this in the preview of the render via NVIDIA LRAY. Why is this happening??
Split to its own thread.
What do you mean? Please attach some images and try to give a clearer dscription of the issue.
I have a gamer's PC with NVIDIA graphics card, which does great with DAZ, but I have encountered an issue with my render that is hard to understand (for me). Why do the default settings render and render preview both ignore the content of the image background and only render the foreground 3D text I manually inserted into the image? The camera shows the full image I want in Cartoon Shaded mode but not in LRAY.. Anyone help pleasee~!

Screenshots attached (the first shows my viewport in cartoon shaded, the second shows the blackness that I get from rendering it, even in preview mode)

What are the Environment settings, in the Render Settings pane? What is the background? What are your lights? I suspect you have no loical lights and the background is a sphere object of some kind, which will block the HDRI or Sun/sky lighting.
How are you lightning your scene?
There seems to be way too little light.
So that's why I suddenly couldn't post :/
What type of background would this be? I'd say it also heavily depends on context, if that background is a so called primitive shape or "just" an image then Iray may have some issues with that, depending on its (material) settings.
But generally speaking it shouldn't be much of an issue with so called backdrops, nor primitives. Did you use the "Environment" tab to set this up or something else? From what I can tell the default IRay settings should have no issues with a backdrop nor a primitive.
Some things I'd check: your render settings, in specific the "Auto headlamp" setting (Iray => General). But also the tonemapper node, maybe you can increase your Saturation by a small bit?
is this what you mean?
I did something to this project that was going well until I realized I needed a better PC to do the render, and ruined it with some lame move in some setting in DAZ.
My project was based on the package called "Castle Gravestone Halls" I bought on DAZ marketplace.
I cannot change saturation for some reason. setting Keeps falling back into the center of the bar.

There is a risk that it is using the old 'ghost lights' that no longer works out of the box, if you are using a newer version of Daz Studio. The luminance has to be multiplied by the reciproque of the cutout oppacity value, if the product hasn't been updated.
No, there is (once you have done a render or added an Environment Settings Node) and environment group in the editor tab of Render Settings. It does sound as if your scene is in a modelled enclosed space, which will block external lights such as the HDR or Sun/Sky modes, or Distant Lights when in a Scene Environment mode.
I guess...there is no way to fix this. I started this project in 4.21 and then got upgraded to 4.21 05 ... and it is messed up in-between different versions with ghost lights and luminance and opacity values. Correct?
The fix is to provide some lights to the scene, whether it be emitting surfaces or light objects.
Emissive surfaces with opacity less that 100% changed befroe 4.21, so that isn't the root of the problem if it was OK in a previous 4.21 build.
Here in the two screenshots, you can see my problem. I have created a new DAZ file and just inserted the basic stone wall tunnel element into the scene, just to test the render. So, when I choose FILAMENT (PBR) it renders something closer to what I want (though it is very pale), but as soon as I hit NVIDIA (LRAY) -- the render preview turns black !?!?! WHY? I have included both the Distant Lights and the Spotlight in front ... and yet ... pitch black :-((((
What is going on ? My settings are normal, as you can see on the left of the screenshot...
Is it a poblem with the NVIDIA driver for Windows? Shaders problem in DAZ?
And which lights is there in the scene?
and what are your Tone Mapping settings (control exposure)?
