Maximum render size with Arnold renderer in Maya

[giovanti]

Hello,

I'm trying to render a large image size with Arnold in Maya.

The max render size I can get is 4096px. If I go any higher, even one more pixel, it'll just say "rendering" for a long, long time. I haven't let it run to see if it actually works, as after about a half hour I just force quit the program. When I use the 4096px, it starts rendering in about 5 seconds, and takes about 14 minutes total to render.

Try enabling the feature overrides one by one to see if you can identify what is causing it to do this.

Could you also provide a Log file and and any details about your scene.

HI, inside maya itself, U cant render more than 8K is so, it will crash depending on ur system resources.

I've rendered 96Kx96K resolution via Arnold itself using .ass file and Kickass , but not within maya, and it tooks like 8 days to rendered and I surprised with the memoery managemed through the render

I just rendered 8192x8192 as a test, at AA=8

But not a complex scene.

Are you rendering scanline EXRs? That could require a lot of memory, because everything has to be kept in memory until the final image is written to disk. In that case, try with tiled EXRs.

Try keeping a thread or two free, so you can check the Arnold log and the cpu/memory usage...

Thanks.
That worked.

For future reference for others:
Render Settings > Common Tab:
Image Format: exr
Compression: zip
[x] Tiled

Was able to render out 8196 x 8196px.
