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>"
},
{
"HOUDINI_PATH": {
"value": "$OCTVERSION"
},
"HOUDINI_MENU_PATH": {
"value": "$OCTVERSION/config/Menus"
},
"HOUDINI_SCRIPT_PATH": {
"value": "$OCTVERSION/scripts"
},
"PATH": {
"value": "$OCTVERSION/bin"
},
"PXR_PLUGINPATH_NAME": {

}
}
]
}
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. On some Linux distributions, you may also need to manually create a libglut.so.3 symlink pointing to the current version in /lib/x86_64-linux-gnu.- If you are having any issues with the Deadline - please submit a support ticket to the AWS.
Happy rendering,
