=============================================
RELEASE 2026.1.0.1
=============================================
PLUGIN FEATURES AND FIXES:
IMPORTANT NOTE:
We updated the octane material node naming and tab menu structuring to align with Octane Standalone and other plugins, so many of the nodes will have slightly different naming or will be found in different submenus. Overall this should be an improvement from before!
Changes:
- QT IPR only draw image when it's needed now
- Fixed canvas zoom stops when zoom factor is 100%
- Added the Shelves tools in the Octane Menu
- Fixed no updating after material node connection changes
- Fixed light id manager UI for windows level UI scaling
- Fixed a typo in ROP and RenderSetup
- Fixed 32 bit image error for image node
- Batch Material Importer - Keep Capitalization based on file names
- Fixed Octane Install script to get Houdini version for solaris version as well
- QuickMaterial 1.2: Fixed Base color doesn't show the texture file picker
- Fixed some weird defaults
- Safely destroy snapshot widget to avoid crash on some mac

Still updating
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.
Code: Select all
{
"enable": true,
"env": [
{
"OCTANE_AUTOSPAREPARAMS": {
"value": 1
}
},
{
"OCTVERSION": "<path_to_plugin_directory>"
},

}
]
}
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
