Need help for rendering

Hi everyone,

I’m actually working on a short film but I’m having trouble making the renders. My level basically consists of a house, a small town and a MetaHuman on an island.

I was able to render the first shots in the house without any problem by deleting the town. Unfortunately, I couldn’t render the town even if I removed the house to save VRAM.

I’ve tried many things: converting as many assets as possible to Nanite, increasing the TlrDelay, rendering in 1080p instead of 4K, reducing subsamples, but nothing works. What surprises me is that in idle I use between 4Gb and 8Gb of video memory, and owning an A4500 with 20Gb of VRAM, I don’t understand how I always end up with the famous “Out of memory”.

Similarly, when I try to convert my level to use World Partition, nothing happens and the parameter remains on “None”. I’ve also tried putting town and house in Packed Level Actor’s, but it doesn’t change anything. My city is mostly made of KitBash3D assets.

So I’m looking for some tips or ideas to unblock the situation as the deadline is approaching and I’m starting to panic a bit.

Thanks in advance (I’m attaching a few screenshots anyway).

Hey @pl_p! Welcome to the forums, and your work looks great!

Are you sure this isn’t a pagefile.sys memory issue? You may need to clear some more “empty space” on your primary HDD to make room for the temporary storage!

Hi @Mind-Brain, thank you ! I’m trying to do my best with this wonderful software.

I’ve emptied almost 100GB of my hard disk and reset my pagefile.sys file (which is about 24GB), unfortunately this doesn’t change anything.
Should I define a larger pagefile.sys?

How many samples in AA are you using?

I remember someone mentioned that splitting the samples helps, instead of using Spatial 16, use Spatial 4 and Temporal 4

i tried it and helped me with my renders

When using pathtracing, my computer runs out of memory at 2048 in spatial. But if i use S 32 T 64, no problem

I’m actually using S 1 and T 16, maybe i can try S 8 and T 8.

EDIT : It changes nothing, I think I’m gonna try to change my city with fewer assets…
