Hey Juanjgon, with this release and, with the AOVs, currently how should someone combine in compositing the Denoised passes? I'm trying to combine the passes to get the denoised beauty, but I can't figure out how to add the denoised Volume pass.
Currently my denoised volume pass alpha contains the geometries as well (I thought it should only contain the volumes alphas).

This can be an Octane core issue. I'll report it to the core devs.kmdani wrote:Hey Juanjgon, with this release and, with the AOVs, currently how should someone combine in compositing the Denoised passes?

I don't use houdini, but this info applies to all Octane plugins.kmdani wrote:Hey Juanjgon, with this release and, with the AOVs, currently how should someone combine in compositing the Denoised passes?

The compositing formula for Octane volumes is:
Code: Select all
"all other beauty passes" * volume mask + volume + volume emission
To recreate the "denoised beauty", your composite AOV output / layers would look like this:
(1) is the bottom layer, (10) is top
All layers are using alpha operation = "Alpha compositing"
Layer number. (blend mode) AOV name
10. (add) Denoised Volume Emission
9. (add) Denoised Volume
8. (multiply) Volume Mask
7. (add) Denoised Remainder
6. (add) Denoised Emission
5. (add) Denoised Reflection Indirect
4. (add) Denoised Reflection Direct
3. (add) Denoised Diffuse Indirect
2. (normal) Denoised Diffuse Direct
1. (normal) Environment (only matches when you enable kernel > "alpha channel" and "keep environment")
All these AOVs need to be added to a Render AOV group, before you can use them in AOV outputs.
Since I don't use houdini, I have attached an ORBX example so you can look at it in standalone. I hope this helps.

Thanks Funk! That really helped me find the problem!
So Juanjgon, what I see comapred to Funk's linked example:
In this verison, the Denoised passes get exported to my multilayer exr, but even if I turn on (on the render target) the Volume tab/Volume mask option, it is not exported to the exr, while in Funk's example it is exported as a separete AOV.
Could you have a look on that?

Checking the forum everyday in hopes to see new ipr for Houdini implemented. Any ETA, Juanjo? Thank you!

Thank you!I want to release the first plugin build including a beta of the Qt5 IPR with all the functions available in the current OpenGL IPR before the end of the year.

it that if you have IPR running and you create an octane light and set it to spot light. If you change the "Lamp radius" while the IPR is running, it instant crashes, and closes, Houdini to desktop, no errors or crash file created, just a fast hard shutdown of the application.
