vray raw image

[irmin]

hi guys,
I would like to know if anybody has any experience in rendering large files over an external renderfarm.
I'm rendering a fairly large image, and it takes forever...
thx for sharing!

Hello there,

What is the actual resolution of your image ?
Rendering Hi-resolution images like 15k takes much longer render-times than 1k for example.
When you double size of the image - render times are at least 4 times slower.
So fo example if 1k image is rendered for 1 hour ,
2k image will take 4 hours ,
4k = 16 hours ,
8k = 64 hours
16k = 256 hours

You can same some time from Global Illumination calculation if you pre-calculate it on lower resolution , and then use it for final rendering on hi-resolution image.

the resolution should be 7016x7016...
I'm running on a core i7 pc, and it's still running, I started sunday morning!!!

Hi,

Is it possible to post a screenshot of your render settings or to send us your scene to: support@chaosgroup.com
And we will try to help.

Hi Irmin
Are you using displacement? Can you share you setting? Usually in that huge render, you don't need high anti-aliasing nor high irradiance map. Your render should not take that long time to render.
Displacement increase the rendering time if you have very high setting.
