They can be found in new "Octane Tools" shelf, or in the Octane right click/network menu.
You can assign shortcuts to any of them by right clicking on the item, select edit tool, and then assign under hotkeys.
- Light Placer - A quick and user friendly way to place lights based on the surface of an object. Works on: Obj level light nodes. Location: Octane Tools toolbar.
- Preview Node - A quick way to preview textures in the material editor, or connect a different material to the output. Works on: Any octane texture type (TEX in material type name) and material nodes. Location: Octane Tools toolbar, and right click menu in network editor.
- Texture Setup - A quick way and powerful way to import a single texture set into Octane when inside a material builder. Works on: Standard Surface Material Node. Location: Octane Tools toolbar, and right click menu in network editor.
- Tri-planar Setup - A fast way to add a tri-planar setup to any "TEX" nodes, (this includes noises etc). Works on: Octane TEX nodes (includes noises etc). Location: Octane Tools toolbar, and right click menu in network editor.
- Batch Material Import - A powerful tool that lets you import large (or small) sets of materials at once. Context: MAT, SOP or OBJ. Location: Octane Tools toolbar, Octane dropdown in network editor.
- Focus Picker - A quick and user friendly way to pick your focus point in the Houdini Viewport. Either select a camera or be in the camera view and run the script. Works on: Obj level camera nodes. Location: Octane Tools toolbar
- Octane Render Setup: This object level node combines the RT and ROP into a single HDA, with all the important controls in one place, making the setup and adjusting of render settings much easier.
- Octane Quick Material: A quick way create and modify materials directly in sops. Ideal for situations where you want to setup a quick simple material (It does support more complex setups as well, but in many cases a custom material setup might be better).
- Octane Material Creator: This node is a utility that makes material creation much faster (and disappears after it's job is done). Based on user input this node automatically creates a material, based on a set of presets, either in a local matnet or the mat context, names it (optional), sets the sops material node up (which points to the material), and then takes the user directly to the material (if desired).
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": {
"value": "$OCTVERSION/dso/usd_plugins"
}
}
]
}
The new Decal object could be created by the new Decal button in Octane shelf or by the new Octane menu in Houdini Network View.
Decal objects will have default texture settings demonstrating how the textures can be set.
If there is an existing object or some primitives of an existing object are set, creating a new Decal object will prompt if the related materials of the existing object should be altered with decal textures so the decal object could affect the existing object's surface.
There are more options in the new Octane menu in Houdini Network View to help you create Octane nodes, insert/delete decal texture into/from an Octane material.
Important Note
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
