OctaneRender 2023.1.3 for Houdini production (2023.1.3.3)

This is a production release of the OctaneRender™ 2023.1.3.3 for Houdini™ plugin compiled with the Octane 2023.1.3 core. This 2023.1.3.3 release is available for the latest Houdini production builds on Windows x64, Linux, and macOS arm64.

Houdini production builds supported by this release: 19.5.805, 20.0.724, 20.0.751, 20.5.278, 20.5.332.

If you are not sure if your Houdini version is compatible with the plugin - just run it and you will see an error message in case of incompatibility.

Linux Note
On Linux only default Houdini builds are supported.
This means that for Houdini 20.0 and 20.5, gcc11.2 builds are supported, and for Houdini 19.5, gcc9.3 build is supported.

New features

Known bugs
On Linux, MPlay IPR may not be working. If you are having problems with it, please switch to QT5 IPR and disable "Render to MPlay" in ROP nodes.
Octane is still working on supporting OCIO V2.3 (the version that Houdini 20.5 uses). The workaround for now is to use the Houdini 20.0's OCIO files when you use Houdini 20.5. e.g. You can use 20.0.751's OCIO file by adding the below line in your houdini.env file for Houdini20.5.

Code: Select all

OCIO = "C:\Program Files\Side Effects Software\Houdini 20.0.751\packages\ocio\houdini-config-v1.0.0_aces-v1.3_ocio-v2.1.ocio"

- Support Attributes and Tessellate properties for packed instance objects
- Show attributes in packed geometries in ObjParms ->Octane->Attribues
- Source node of instances should be visible when rendering if it is required
- Support attributes of multiple packed items instances
- Avoid reloading the whole scene (could cause update performance) after universal light update

Common Issues and Solutions
- If the plugin doesn't work at all, set HOUDINI_DSO_ERROR = 2 in houdini.env and check for messages in the terminal.

Happy rendering,
Your OTOY Team

Instances are always rendering whether the display flag is on or off.

- Support instance by primitive "filenames" and "index" intrisic attributes

Does this mean it's possible to time offset animated instances?

- Support instance by primitive "filenames" and "index" intrisic attributes

Does this mean it's possible to time offset animated instances?

Yes it should now be possible to have the render match the viewport in that regard.

Instances are always rendering whether the display flag is on or off.

I had a look, it seems it is more the viewport update. Starting and stopping at each frame does hide it but we will look into it.

Thanks for notifying us!

Ok. I can't seem to get it to work. It's still unpacking the instances in render time. Triangle count is not the same as you can see.
Maybe i'm doing something wrong or i just don't understand what it's supposed to do.

Not using intrinsic index attribute

Using intrinsic attribute to offset animation

It's the same when rendering to disk.

That looks right to me, if you open that scene in the previous builds you will see the test geo animate all at the same time.
Rendering one item of that test geo will yield about the same VRAM usage as what you have for all instances.

We will be doing a fix for this asap (maybe by tomorrow)

Tested it in the previous version and it is as you said.
This is such a game changing feature. Thanks
