OctaneBlender Addon 2025.3 - 30.7 Beta Release [TEST]
Posted: Tue Sep 09, 2025 7:55 am
We are excited to bring you the latest beta version of the OctaneBlender addon!
This version works on the "vanilla" Blender you can download and install from the Blender Foundation website ( https://www.blender.org/ ).
This means there's no need for a custom build anymore!
Running the Octane server is still needed.
Here we have the optimized addon version ready to be released on the forum as the Beta.
Generally, this version includes significant changes that dramatically improve performance, and dozens of new features and bug fixes as well.
We will continue developing/updating both the addon and non-addon versions, until the addon version can be declared stable.

How to Install
