Large Scale Render.. funky results

[RyanH1984]

Hello all.
Has anyone had any similar issues when rendering big. (12000x 8000)
Here are two images side by side:
Left is using the Up sampler so I guess this is rendering 6000x4000px.
The right image is with up sampler turner off as I don't like the Alias it creates on the edge. However there's some odd results and parts of the image missing.

Hi,

Are you rendering local vs network? Are the GPUs all the same?

Thanks for the Reply Anton.

Apologies I should of given details.
I'm Rendering Local. Though The files are on an External SSD I have plugged in (Not sure if that would be an Issue). The file is renderd to my computer however.
I'm Using 2x RTX 2070 super I've tried both with and without NV link.
I've tried Both C4d and Stand alone. Something just doesn't like a single image that size. I have read that the Denoiser throws a Hissy at Large Scales.

I found a solution to use the Camera Tiler in contend browser and then composite 4 separate images together in PS

Cheers,

Ryan

Hi,
you have not enough RAM for that resolution. For large resolution rendering you need a lot of system RAM to handle the huge frame buffer.
