Render very high res images with Corona 1.5

[sumeetgupta]

Hi,

We are typically asked to deliver high res images above 5K for example. And we always face memory issues with corona when we try to jack up resolution more than 5 or 6K. Is there any trick  available where we can define corona VFB to show 1/2 or 1/4 during rendering and we can later save it as an EXR with actual resolution of the image ? Or some other way around ?

Thanks.

There are some ways to optimize memory, such as rendering in tiles. Also, this greatly depends on the scene you are rendering. For example if you have displacement in your scene, you can lower its quality to get less memory usage. More info:

Thanks Maru. We dont have any displacement in our scene. We do have lots of coronaproxies. This article is for vray and works like a charm but can we implement for corona as well ?

Rendering in tiles with Deadline or in stripes with Backburner should be an easy and fast solution. That's at least what worked the best for us while keeping the same quality level.

Thanks, I think that's the only possible way to render high res images as of now.
