Sorry for the Open Image Denoise problem again, I've followed what's been shown here viewtopic.php?f=102&t=83264&start=20
but it's still not working

The attachment baa119da208c070d216f20dfd51fc53.png is no longer available

I do realize there can be lots of work behind and the document might take extra time to get up to date but it'd be really appreciated if you can provide some example hip files along the new release to show how to use certain new features.
Also I've attached the problematic hip file.

Hi LewisO, it seems to be working, as you can see the solid being rendered. You still need to add AOVs and possibly enable Alpha under Kernel settings.

Here is another example and HIP file, it is using 25 samples and denoising 2 separate AOVs, you can scrub in the timeline to see it update.
Make sure you select the OutputAOV first.

I do agree about the release info and we will try make sure additions like this have info on the release page in future, sorry for the inconvienince!

This is immensely helpful and the demo should be the go-to example! Thanks so much!

I didn't add everything in the example, but it should be enough to experiment with and find what works for you for your task. (You can also use Opacity and Mask by layer etc.)

That's another that confuses me, it seems like the nodes are inconsistent across different DCC plugins and the standalone.
As you can see in the standalone and the C4D plugin, you can easily pipe in a color to the Mask with Layer group node, but the color input seems to be missing in Houdini and I can't figure out how to use it like the standalone/C4D plugin

That looks like a bug or oversight, thanks for bringing it to our attention!

I'm getting this Console Error appear when I plugin a Vertex Displacement or Displacement node into the displacement channel in a Standard Material.
It doesn't appear to affect the displacement node as I can see it displacing when I change the height value.

(1055)
*** OCTANE API ERROR: Tried to access null node pin
*** OCTANE API ERROR: Can't read float from static pin 'unknown' (P_UNKNOWN, type PT_UNKNOWN) of node '' (NT_UNKNOWN, 00007FFDC2C37D70)

Have to say I'm impressed with the speed at which the displacement works tho!

Hi Aszyk, I had a look now and tried procedural with bake node as well as the image nodes - both Vector Displacement and Displacement seems to work.

Can you please send me the scene you are getting the error with (or simplified), and also which OS and build you are using. Thanks!

Hey Ricky, here's a stripped down version of the file with just a cube and a procedural texture and I still get the error.

I'm on windows 11 Pro - 10.0.22631 Build 22631 and Houdini 20.0.653
