This Addon Release is only compatible with Blender 5.1 - previous Blender 5.0 and 4.x releases are not supported.
This version works on the "vanilla" Blender 5.1.2 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
- Unzip the Octane Addon Server in any location on your hard drive
- Launch the Octane Addon Server
- Launch Blender and from Preferences/Addon, install the Octane for Blender addon
- Select File > New > OctaneRender Startup (Direct Lighting) or File > New > OctaneRender Startup (Path Tracing)
- Quit Blender
- Launch Blender again
CHANGES SINCE LAST RELEASE
- Supported point cloud display color as Octane color attribute
- Supported "Always use camera resolution" for OSL cameras
- Added "Use Object Layer for Instances" (default off). When on, the collection's Object Layer applies to all of its instanced children; when off, each child keeps its own Object Layer
- Fixed loss of Object Layer on collection instances
- Fixed the Local DB list not refreshing without a server restart
- Fixed imported Transform value nodes becoming Camera Transform
- Minor Bug fixes
