Trouble with .exr exports. Missmatch with IPR. Missing AOVs

[adriansayago]

I'm trying the OCIO/ACES workflow and I'm really struggling to get an .exr export that looks as it does in the IPR. Also it gets exported as 32-bit EXR despite specifying 16-bit in the settings.
I'm also having trouble getting the AOVs rendered and included in the exr. I've tried to find a solution in the documentation to no avail. Con someone help me out or point me in the right direction?

What OCIO, Houdini, and Octane versions are you using? Can you share your scene to take a look at your config?

Thanks,

Hi juangon, I'm using houdini 19.5.493 and octane plugin 2022.1.0.6

Here's the file https://drive.google.com/file/d/15iMTqj ... sp=sharing

My config might be messed up because I've been trying all kinds things to get it to work.

Thanks for your time.

There is no plugin build for H19.5.493 yet. The Houdini and plugin versions must match. Have you tried to use H19.5.435 and its proper plugin build?

Thanks,

I'm trying with H19.5.435 but it seems I'm facing the same issues. The missmatch between IPR and rendered exr still there and still exports as a 32bit file instead of 16bit.

I've been testing your scene here and the 16/32 EXRs files work as expected. The 32bit ones are bigger that the 16bit, and the multi-layered EXR file has all the AOVs that you have enabled in the render target. Doesn't it happen in your case?

About the difference between the IPR and the EXRs, what OCIO config are you using? Be aware that the IPR color settings must be configured in the render target, while the EXR export settings are configured in the ROP node. I know that this is something weird, but this is how Octane works ...
