Custom Image Size

[JoryRFerrell]

Will there be native support to make images up to or even over 10000px in the future? Yes...ten-thousand....I uh....sort feel limited at the current highest resolution.

The latest beta supports 8kx8k which I think is the current limit for GPU and cuda.
I am curious what size you would like if you had a choice and what you use it for. Is that arch viz?

Edit: Sorry I didnt realise before this post was in the Demo forum. Some of my previous comments about functionality under development are not really appropriate here so I removed them.

Hmm...did not realize the limitation in size was directly related to hardware bottleneck. I'm relatively new to 3d design so I haven't looked into the supporting hardware and the limitations posed on the videocard. I'd assumed it could make as large an image as you wanted, with time to render being your only limitation. Thanks for informing me. As for what I would like those size images for....the more pixels the better if you plan on enlarging your images. Poster size for instance.

An A1 size sheet is 840x594mm. Full coverage at 240ppi is 7937x5612px which fits in 8k.
I am not sure you will find a large format printer that does any more than that. Usually its 200ppi.
Many posters would be 150ppi which on an A0 sheet is 7015x4950.
I am not sure that 8k is an issue.
Not only do you need to render quite a while to get an image that big (in any renderer not just Octane) but you need to be able to physically print it.

Christ...you know your shit...
but anyways...I had planned on sending my work off to a company to have posters made.

I confirm than 150 ppi for a A0 or even a A1 poster is plenty enough.

300 ppi for an A4 is really common.
But you don't watch a A0 poster at the same distance as you look at an A4.
So actually with the 150 ppi on an A0 you have a relative much better resolution than 300 ppi on an A4.
To understand resolution you need to have in mind the eye capability to see the difference between two pixels.
If you are far your eye cannot make the difference between bigger pixels.

I know it's not octane topic but I couldn't resist to tell this.
It's a very common misunderstanding about resolution.

Just to let you know feature films are very often rendered 2K and seldom 4K as far as I know never 8K.

Even A3@300ppi is only 4960x3507 ie.well under 8k.
I'm not sure but I think 240ppi is as high as you need go for 150lpi scanning for high quality offset print. Glossy magazines 200ppi and 133lpi?
Not my area of knowledge - I bet someone reading here will know though ...
