Urgent - Pathtracer renders black | C4D

[monomagnus]

One minute everything's fine, have been working on the scene for two days, doing test renders, all good.
Then I'm enabling Render Passes to get my Z-pass - dumbest mistake of my life.
Pathtracer turns black (both Live view and Render to Picture Viewer), and I can't get it to render for the life of me.
DL works fine, I can view Z-depth and multiple other passes, but PT JUST. WONT. RENDER.
The night before deadline. I can't believe this.
About to render 700 frames overnight, and this happens.

RTX3090, 32 core Threadripper 256GB ram, everything should be fine.
C4D S24, every driver updated. I literally only enabled render passes and it broke.
Other scenes render PT fine.
Working with Octane and a deadline gives me a heart attack.

Please please please help.

Can you render without passes? Did you try to render with less resolution and closed other apps? Do you see any error messages in CONSOLE window?

Literally everything else worked except pathtracing in that C4D scene, even when resetting every setting I could, both Octane and C4D settings.
Tried turning denoiser on/off, no volumes.
It actually renders through the samples, but everything's black. No errormessages from the LiveViewer.
I solved it by selecting everything in the Objects pane, copying and pasting into a new C4D scene and rebuilding what I had to.

Here's the problem project, if you're interested : https://www.dropbox.com/s/7cazalcatlzb4 ... t.c4d?dl=0

This parameter is disabling the all lights. I think you changed it accidentally.

Thanks for the reply - yeah that solved it.
I don't even know what that does (yet), is there any reason why it wasn't reset when I reset setting I could think of?

It's like an overlook on reset for this part. I'll check it
It's part of light linking feature. When you set it enable, all unchecked IDs will be inactive. That's why you have black output.
