OctaneRender 2024.1 for Houdini production (2024.1.0.2)

[bruce.chai]

This is a production release of the OctaneRender™ 2024.1.0.2 for Houdini™ plugin compiled with the Octane 2024.1 core. This 2024.1.0.2 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, 20.0.751, 20.5.278, 20.5.332, 20.5.370.

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"

Important Note
This version fixed the problem that the layered material nodes cannot be loaded properly, however this fix affects all layered material nodes and OSL material nodes in existing saved .hip files. When loading a .hip file for the first time using this build, it's necessary to adjust the connections of these nodes. Once the file is saved with the updated connections, the issue will be resolved.

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

Thank you for this update!

Which link should I use for compatibility with Houdini 20.5.278?

[lavrenovlad]

Awesome release, thanks, hopefully no hiccups and it runs stable.

The issue with multi-input nodes like OutputAOV,CompositeTexture etc. hasn't really been fixed? I re-opened the HIP file, wires aren't broken, but all the nodes are connected to the first input (which shouldn't be possible). And I need to unwire everything and re-wire so they work again..

Did you open then reconnect in this new build and save - opening again after that the links are broken again?

Hey there futoryan, we are only supporting the last 3 latest production builds and last 2 version builds. Please consider upgrading to a new version.

Yeah. Now I ran a test on a simple new scene and it seems to work. So I tried to replace all the compositveAOV nodes in my actual project to make sure they were freshly added and rewired and for some reason it seemed to fix the problem. So, all good for now!

[lavrenovlad]

I experience a weird behavior with Material Composite node, it adds inputs like crazy with each time I wire/unwire something and crashes Houdini too. Could you check? It seems that the node is completely messed up.

I can confirm yeah, that is weird. It seems to be creating new properties where it needn't - thanks for the report - appreciated!

[lavrenovlad]

One more thing, it feels like the IPR region tool isn't really stable with the denoiser turned on. When I run OIDN in constant denoising mode with region tool sometimes some actions in the material editor can cause blackouts in the IPR when the denoiser kicks in (need to wait for the image to appear back), and sometimes it crashes.
