Got a strange issue whenever I try to render this scene, even with default settings 'out of the box'...

Cannot get it to render in any way whatsoever, just get a solid black screen?  Any ideas?

Have you checked that your camera isn't inside an object?

TATSU 3D

Yeah, double checked all the usual suspect causes. I've tried cameras from different sets, at different angles, inside the building and outside, all just renders solid black in a matter of seconds.

Is your envirinment set to "Scene only"? If yes, it could be dark due to lack of light.

TATSU 3D

Nope, checked that one too. It's set to scene and dome

What does your log say?

Set it to Sun-Sky and see what happens.

Alright, if I set it to 'Dome & Sky' - black render.

If I set it to 'Scene only' - black render

If I choose 'Sun/Sky only' - blank/transparent render

 

It's just not wanting to render with any settings. Strange as I'm not having any issues with any other scenes.  Saying that, I have been having trouble with more recent Fugazi scenes really ramping up the RAM usage for some reason, then failing to render.

I'm running Win10 64bit with 64GB RAM, with 2x MSI GTX 2080ti's so memory really shouldn't be that big of a problem for me!

One thing I did pick up on there is that it said no device specified or usable, and no worker to work with?  Is this relating to the GPU's?  Checked in render settings ant they're both checked, as they always are...

If you had attached the log file to your post instead of copying a part of it in textbox, we could tell you more, but the part you copied tells us that you have no devices that meet the criterias for DS to render in IRAY.

Your cards may be the wrong type, too old or the drivers are not supported.

That doesn't explain why I can render any other scene without the same error.

Can't explain without more information on your system, hence the request for the logfile.

See if any of the components of the scene has an RSL shader instead of an MDL, that can cause it.

Save the scene, restart DAZ and try again... when I get that error this would usually help. If not restart the computer and then try again.

I'm not that well-versed in the log file, but using 2.2 million triangles and 629 textures seems like a lot.

What products are you trying to render, specifically? (Per the forum rules, you're supposed to explain your issue in your first post, not just leave important info in the title.)

Doing some quick math, 629 JPGs at 4K resolution is almost 32 gigabytes of memory, and that's not even including the geometry. If you exceeded the VRAM and have CPU fallback disabled, I believe that would also produce a blank render.

This was my first thought as well.

This scene is pretty unoptimised out of the box and uses nearly 5gb of vram (dependent on texture compression) so you need at least an 8gb card if you want any hopes to render it with a single character. Splitting the scene out in to exterior/interior groups that can be hidden depending on shot requirements, hiding unseen clutter, replacing some textures with tiling textures (all interior walls have their own unique maps despite not being different enough to warrant it), removing some generally unnecessary metallicity and rougness maps can bring that overhead down.
