Hello,
I'm having trouble the AOV passes (cryptomatte node name, denoised reflection etc...), they show up in the IPR but they are not saved when I render to disk.
I'm new to Octane for Houdini, did I miss something ?
Thank you in advance

Thank you for the post.
OctaneRender for Houdini EXR outputs uses HDR tonemapping requiring us to use compositing applications like AE or Nuke.
In AE/Nuke, we need Cryptomatte Effect/plugin to see the AOVs or please try render in PNG formats if that works.
Let us know how it goes!!
cheers

Oh, I didn't understand that it was a multilayer pass rendering, I was expecting different files names... so I have to use extractor to get reflection pass for exemple ?

We can render the AOVs as different files names too.. Please uncheck the `Save layered EXR`
If its PNGs then we save out as separate AOVs.
Let us know if that works!

Thank you for your time, it's working !
I have a request though, in 3ds Max the passes have clear and readable names, in Houdini the acronyms are hard to work with.
Exemple : Test.OctaneRenderSetup1.cm-Mnn.all.0001 -> Test.CryptoMatte-Materialnodename.0001

Yes, we have integrated a new `OCTANE_PASS_NAME` tag for the next build.
Adding this tag will render the passes/AOVs as full name.
