We are excited to bring you the latest beta version of the OctaneBlender addon!

This Addon Release is only compatible with Blender 5.0 - previous Blender 4.x releases are not supported.


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.

OctaneRender 2026.2 Integrated with Blender 5.0 Officially Released (Simplified Chinese Support)
OctaneRender 2026.2 与 Blender 5.0 集成版本正式发布(支持简体中文)

我们很高兴宣布,全新的 OctaneRender 2026.2 与 Blender 5.0 集成版本现已准备就绪!这是首个支持简体中文界面的版本,旨在为中文用户提供更加友好、高效的使用体验。

这是一个重要的里程碑版本,我们也欢迎大家在日常项目中积极测试和反馈,帮助我们持续优化中文本地化质量和整体使用体验。

感谢大家一直以来的支持,祝创作愉快!

Octane 简体中文翻译的启用方式与 Blender 原生中文界面保持一致:
  • 如果您的 Blender 已经设置为简体中文界面,则 Octane 插件的简体中文翻译将自动应用,无需额外设置。
  • 如果您的 Blender 当前不是中文界面,则可通过 Blender 的经典方式切换至中文,以启用 Octane 的简体中文翻译:
    首选项(Preferences) → 界面(Interface) → 语言(Language) → 简体中文(Simplified Chinese)


Generally, We have migrated most of the features from the non-addon version, to this addon version.
  • Updated to Octane 2026.2
  • Added Metalness AOV
  • Marking deforming meshes as “Reshapable” is no longer necessary, as deformation is now handled automatically, though users can still enable it if they prefer.
  • Meshlet: include blend filename and mesh data name in meshlet ID. Prevent conflicts when duplicating meshes.
  • Updated startup scenes
  • Implemented cached Octane resource nodes during animation rendering
  • Added Octane resource cache support for animation rendering

Bug Fixes
  • Fixed OSL Camera issues
  • Fixed camera transform when rendering the first animation frame
  • Fixed update issue when switching static/dynamic front projection
  • Fixed wrong front projection transformation
  • Fixed static front projection "not static" problem when using animation rendering
  • Fixed object layer update issue when switching back to default settings
  • Fixed dozens of default bit value issue when using light mask
  • Fixed object layer color node non-sync issue
  • Fixed OCIO initialization issue
  • Fixed tracekbacks
  • Updated Chinese texts accordingly
  • Minor Bug fixes

  • Quit Blender
  • Launch Blender again
Now you can use Octane on the most current official Blender version!

As with all beta builds, we advise to not use this release for production purposes.
We are trying to, but we can't guarantee that scenes saved with this version will be compatible in future releases, so, again, do not use this beta for production work.


Usage
  • Start with a default scene (File > New > OctaneRender Startup (Direct Lighting) or File > New > OctaneRender Startup (Path Tracing))
  • Convert a scene from the non-addon version: "File > Export > OctaneBlender Addon". Please report any problem you may find when converting your scenes!

As this is a Beta release, you may find issues. Please report any bugs and/or missing features, possibly providing the scene and steps to reproduce the problem.

Some converted scenes may not work properly - please report any of them.

Bugs & Issues

This is a beta version, so there may be issues and bugs. Please report any bugs and/or missing features, possibly providing the scene and steps to reproduce the problem.

If you are unable to share the scenes, please try running Blender in debug mode and send us the logs.

How to run Blender in Debug mode
  • Open the directory of the Blender executable file.
  • Double-click the blender_debug_log.cmd file to open it.
  • This will launch Blender in debug mode and automatically start capturing logs.
  • Reproduce the issue you are experiencing in Blender.
  • Once you have finished reproducing the issue, close Blender.
  • Blender will open a folder containing error log files.
  • You can then send us the blender_debug_log.txt file to help us diagnose the issue.

You can get more information about the debug command at https://docs.blender.org/manual/en/latest/troubleshooting/crash.html.

When loading some older projects in this new version, you may notice that color textures appear brighter in the render.

This happens because the Legacy Gamma option in the RGB Image node no longer works correctly unless an OCIO Color Space node set to Linear sRGB + Legacy gamma is added.
This is particularly noticeable for image textures connected to the Albedo input.

To help with this, I've created a small addon that automatically adds the missing OCIO Color Space node where needed.

Once installed, you will find the following options in the Octane sidebar:

Smart Exclusion (tries to exclude "non color" nodes attached to Roughness, Bump, Opacity, Displacement etc. and so on)
  • Active Material
  • Selected Objects
  • All Scene Materials
All Images nodes (adds the OCIO nodes to all connected Image textures nodes)
  • Active Material
  • Selected Objects
  • All Scene Materials
These tools will automatically detect image textures connected to the Materials and insert the required OCIO node.

I hope this helps!
