This Addon Release is only compatible with Blender 5.2.2 - previous Blender 5.x and 4.x releases are not supported.
This version works on the "vanilla" Blender 5.2.2 release, that you can download and install from the Blender Foundation website ( https://www.blender.org/ ).
The installation consists from two parts:
1. OctaneRender™ Server
2. OctaneRender for Blender Addon
How to Install
- Download the addon and the server files
- Run the Octane Addon Server installer (or, if you downloaded the ZIP file, extract the Octane Addon Server zip file to any location on your hard drive)
- Launch the Octane Addon Server
- Launch Blender and from Preferences -> Add-ons, click on the small arrow at the top right and choose "Install from Disk..."
- Select the downloaded .zip archive of the Octane for Blender addon
- Select File > New > OctaneRender Startup (Direct Lighting), or File > New > OctaneRender Startup (Path Tracing)
- Quit, and then relaunch Blender
