Release Notes
=============================================
RELEASE 2026.6.0.0
=============================================
PLUGIN FEATURES AND FIXES:
New features and improvements
- New $OCTANE_PASS_NAME variable for output paths (Octane ROP and Solaris). It expands to the pass's readable name. The existing $OCTANE_PASS still gives the short name.
- Float Image texture: choose the output type. The output can now be float or color3. Scenes saved with earlier versions open with color3, so they render as before.
- Animated OBJ display parameter is supported, so IPR will match Houdini's native viewport when OBJ's display parameter is used.
- The IPR snapshot now matches the current render region / film region.
- Ctrl + mouse zooms the canvas in render region, film region and snapshot compare modes; tooltips show when canvas pan and zoom are available.
- The image buffer was reworked, so the display is more reliable.
- MaterialX nodes that are Octane node graphs are now supported (e.g. mtlx separate nodes).
- createPackageFileForOctane_NoSceneIndex.bat should be no longer needed, and will be removed from future releases, so please report any problems with createPackageFileForOctane.bat
- Fixed a crash when clearing the Tile Grid image node's File List.
- Fixed instanced analytic lights losing their instance color when reloaded.
- Fixed ORBX exports missing assets for scenes with RGB image nodes using COP buffer.
- Fixed the Texture Switch input slider having a huge maximum.
- Solaris: octane:* camera or light properties now updates the IPR straight away.
- Solaris: the Universal Camera's custom aperture color space parameter no longer fills the undo history.
Note
From 2025.1.Beta_1.0, Octane plugin for Houdini uses Houdini package file. Each build ships a script (createPackageFileForOctane.bat for Windows, createPackageFileForOctane.sh for Linux and Mac) to help create the Octane.json file as below under C:\Users\<username>\Documents\houdiniXX.Y\packages on windows, ~/Library/Preferences/houdini/XX.Y/packages on Mac, or ~/houdiniXX.Y/packages on Linux.

2024.1.0.2 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.- If you're missing
libglut.so.3, install the freeglut package.- If you are having any issues with the Deadline - please submit a support ticket to the AWS.
Happy rendering,
Your OTOY Team
