Saving .exr files with denoised render elements?

[arqpv]

Hey guys,

I'm rendering some animations and I'm trying to skip using .cxr format and going straight to exr. It works well except that I'm not getting any denoised passes in the file.
in the render output dialog I'm setting my save file as .exr and in the setup window, I check 'automatically add/remove render elements from render dialog'. So all my render elements are in there, but there's no denoise anywhere.
In the scene tab, Denoising is set to 'corona high quality'.
If I render this as a .cxr, then rename the file to .exr, the passes are there, denoised and regular, an many others that I don't need.

Is there a way to get the denoised passes in the .exr file without having to use .cxr ?
thanks!

This is strange because you should get a denoised beauty only with this setup. The non denoised should be the one missing (which can be obtained by adding a CShading_Beauty element with denoise amount 0).

Please add at least Corona + 3ds Max version information and if you use single node or network/dr.


Good Luck

Hey Frood, thanks for your reply!

We use 3ds max 2024, corona12, and we render through Deadline as a render manager. No distributed rendering.
But either if I render locally on my computer, and select my file to save as .exr with automatically add render elements, or if I send it to the farm with the same settings, the outcome is the same.
I'm actually seeing that corona takes the time to denoise at the end of the render, but is just not saving those pases in the exr, as it does with the cxr.

I did a test rendering locally, once saving as .exr, and once saving as .cxr.
the exr file is 133mb and the cxr 872mb. Clearly there's way more layers and information in that one.

Does anybody from corona have a better workflow for what I'm doing or is it just a bug ?
if anybody has suggestions as well, they're all welcome,
thanks guys !

Hi,

yes, CXR has a lot extra layers (and metadata), thus the size difference (actually the reason to have a "CXR" primary). As mentioned, the denoised pass should be in your EXR. It may be any issue with deadline though, your setup is correct imho. But if the denoised beauty is not in your locally rendered EXR, it could be a Corona bug as well. Just to make clear: you are using Corona v12, not v12.1 or v12 update1?

You could delete all objects from your scene and attach it so we can have a look at it/test it - or start a ticket if you like that more.


Good Luck
