-Installation steps-
Insert the OctaneRender® plugin folder path to the houdini.env file. Houdini®creates this file after launching it for the first time.
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 = "C:/path/to/octane/bin;$PATH"
Setting this environment variable outputs any error related to loading the OctaneRender® plugin on the command line for diagnosing installation problems:
HOUDINI_DSO_ERROR = 2

Linux Note
On Linux only default Houdini builds are supported.
This means that for Houdini 20.0 and 20.5, gcc11.2 builds are supported, and for Houdini 19.5, gcc9.3 build is supported.
Important Note for this release's Mac build
Octane Render 2024.1.2 pops up a window asking user to agree or not agree to collection of anonymous usage information and statics. This window conflicts with Houdini's splash window when Houdini starts, you will not be able to click Yes/No button in the Octane Window. Octane core team is working on fix this. But before this is properly fixed, there is a workaround for this. You can press Y/N when the Octane window is popped out behind the Houdini Splash window, and this only needs to be done only once. The attached video shows the workaround for this issue.
