Hi res rendering problem

[BorisGoreta]

I'm having problem rendering an image in higher resolutions.

Initially I was rendering it at 2752x1416 and it all went fine. Now the client asked for a higher resolution render to put it on a big billboard so I upped the resolution to 1700x8712. IPR sets the correct aspect of a preview window and it all renders fine. But when I use F9 rendering, the render preview window sets the correct aspect but the resolution and zoom of an image is wrong. In X axis the image is twice as small and in the image I can see too much in Y axis as if the zoom factor became smaller.

I need to provide the client with this image ASAP, is there a quick fix to render it properly ?

It renders fine if the X resolution is around 9000 or less, if I go bigger then 9000 I get those distortions.

If I set it to F9 render at 20000x10274 I get a 8192x8192 resolution image.

I'm fairly sure LW used to have a render limit. It may even have been 8000x8000 so it could be that. Try a non octane F9 at the size you want to see if it's a LW issue.

There wer plugins to split up bigger camera sizes, but dont' remember what they were.

Boris, you can't split this bad-boy in two with render region?

I am going to test it ASAP ... I never try to render at this resolution before.

I think that Octane can't render a image bigger than 8192x8192 ... a GPU limitation?

[juanjgon]

Yes ... I can only get a 8192x8192 image ... Octane frame buffer can't be bigger. I will try standalone to see if there it works.

[juanjgon]

Also Standalone can't render images bigger than 8192x8192 ... this is a limitation of Octane, perhaps due some kind of GPU texture or frame buffer size limit

Perhaps you could use the limited region to render it ...

Ok, thanks for getting to the bottom of this. I will use limited region to render 4 images and then stich them in PS.
