Installing OctaneRender^® For Houdini^®

The release archive contains everything you need to run OctaneRender for Houdini, including the Octane libraries, plugin binaries, menu shelf, HDAs, etc.

Compatible Houdini Products

• The OctaneRender for Houdini build must match your Houdini install to avoid problems.
• The OctaneRender for Houdini plugin requires Houdini Indie, Houdini FX, or Houdini Education.
• While running in Houdini Indie, the plugin limits the sequence rendering resolution to 4k, and it disables the scene export and cloud features.
• Houdini Apprentice^® cannot run the OctaneRender plugin as they lack support for third-party renderers.

Plugin Installation

To install OctaneRender for Houdini, decompress the archive you download from the OctaneRender website and copy the resulting uncompressed files somewhere.

Insert the OctaneRender plugin folder path to the houdini.env file. Houdini creates this file after launch it for the first time.

The location of this file varies for each platform:

• Linux: ~/houdini19.5/
• Windows^®: C:\Users\<user>\Documents\houdini19.5
• macOS^®: ~/Library/Preferences/houdini/19.5/

On Linux and macOS^® systems, append a single line to enable OctaneRender:

HOUDINI_PATH = "/path/to/octane;&"

On Windows systems, you need to set the PATH to point to the plugin bin folder as well:

PATH = "$PATH;C:\path\to\Octane folder\Octane_2022_H19\bin;&"

HOUDINI_PATH = "C:\path\to\Octane folder\Octane_2022_H19;&"

The HOUDINI_DSO_ERROR Variable

Setting this environment variable outputs any error related to loading the OctaneRender plugin on the command line, which is useful for diagnosing installation problems:

HOUDINI_DSO_ERROR = 2
