Blank render driving me insane

abelundercity_7fb40cbc22

I tried all of my usual fixes (reducing line tesselation in strand-based hair, ditching strand-based hair, removing literally everything that doesn't appear in the shot, shutting down and restarting fresh), and so far all for naught [my render is still blank].

It's a simple scene with only one Genesis 9 figure. It should not be this hard. 

 

I'm running Windows 11 with 32 GB RAM, GPU is an Nvidia GeForce RTX 2060 with 576.52 Studio drivers.

 

Here's the log file for the crash:

Thanks in advance for any advice!

In short.

You are running out of VRAM, and CPU fallback not allowed, so nothing.

Which subD has character or clothing?
