Here is our first 2026 Alpha release!
Please note that this is an experimental alpha both for Octane and for the Octane C4D plugin. Octane features and Plugin implementations will be subject to change.
For the next release (1.7.1) we will be focussing on stability and fixes, if you have pressing issues you want fixed, let us know.
To see what the future holds, check out our Trello!

2026 Alpha 3 - v1.7.0 plugin revisions
Octane 2026 Changes:
- Added Meshlets (Experimental). Accessable via the Octane Object Tag
- Added Tracesets. Accessable via the Octane Object Tag
- Added Gaussian Splats
- Added MaterialX nodes (Experimental)
- Added Vectron operators
- New Texture Displacement (Experimental). There is a currently a stability issue with the new texture displacement in Octane.
- Octane Object tag on a clonder is now applied to its cloned items (if they dont have object tags of their own)
- Cloners in Multi-Instance mode now correctly displayed in a Custom AOV
- Chaos Texture performance improvements. (Underlying issue is still present in Octane, we are currently investigating a permenant solution)
- Fixed issue where converted RS materials used absolute paths to osl scripts
- Z value of noise4d node is now also scaled
- Improved converting Universal material to Sub-Material
- Color Picker in the Live-Viewer works again
- Changed utility default color
- Rearranged Vectron Menu
- Submaterials now use spheres as preview
- Custom AOVs do not lose custom naming after being packed with the C4D Wizard anymore
- Fixed a bug that prevented creating a Render Region after rendering in PV
- "Get Last Region From Live View" command now correctly updates the right border value
- Removed "Tag" from "Octane Rest Position Tag"
- Standard Surface Material: Subsurface Scale slider max value changed to 1000
- Standard Surface Material: Opacity Slider now correctly set to 1.0 by default
- Shape field is now hidden on Texture Fields when it is not used
- Dynamic pin/port are now numbered correctly (Effects decal objects)

Support
Some important notes about these builds:
The minimum NVIDIA driver version that is required by this version is 528. You can launch Octane with an older driver version, but it will fail to render and it will produce an error message in the log.
Open Image Denoise is supported on CUDA compute model 7 and later, we fallback to the CPU version on machine with older models.
IN ANY CRASH CASE PLEASE DO THESE!!!
If you see CUDA errors follow 1,2,3,4.
1- Use NVIDIA STUDIO drivers, not Game Ready versions. If you have stability issues try different drivers, some of them could cause instability issues. Make a clean install while doing this to be sure previous files completely removed.
2- Check GPU frequency. Overclocking would cause instability issues
3- Check PSU. Insufficient power output would cause instability issues
4- Check the free amount of GPU's VRAM and system's RAM while working. Low VRAM will/may cause CUDA errors. Be aware of some generator objects will have different triangle count in Picture Viewer than Live Viewer. It’s like “editor/render” parameter. Just try to use the same value. Also try to optimize your scene for polygon count, even use smaller images. Try to use Octane texture nodes rather than using C4D texture/shaders.
Alternatively, use V4 and Out-of-core(OOC) function. Increase RAM for OOC and It should not exceed physical RAM amount. Check TDR value and increase if it's necessary.
5- If you see C4D crashes without CUDA errors, then send us bugreport.zip, screen-shots and video capture to show process and crash moment. Also please send us a sample scene in a format of C4D or ORBX to let us investigate and test it. Alternatively, try to delete/hide some objects/materials until crash gone away. If you find what's causing crashes, send us a sample scene to let us for investigating and bring a fix or solution.
Thanks for helping the development by your feedbacks! It’s impossible to quickly catch every case without user feedbacks! It’s the same procedure as other companies do like Maxon/etc...
Please note the macOS build will only work correctly on macOS 14.5 and newer, and only on Apple Silicon.
Requirements:
-You'll need to update your Cinema 4D to latest versions(R21.115, S22.118, R23.110, R24.111, R25.117, R26.107, R2023.2, R2024.4.0, R2025.0.2). Otherwise, the plugin will not work and not appear in menus.
-Internet connection for activation, be sure that C4D and Octane will not be blocked by the firewall and any antivirus software.
-Nvidia drivers at least Nvidia Studio Drivers(minimum 528) and be careful with latest Game Ready drivers which can cause cuda errors. Stay with stable one for you.
ONLINE HELP MANUAL
Use embedded help buttons from Octane nodes and windows
or from link: https://docs.otoy.com/cinema4d/OctaneRenderforCinema4D.html
Archive Installation
First, remove all octane related stuff from plugins and the main folder of Cinema4D.
Extract all files to Cinema4D\plugins\c4dOctane directory.
Also, download manual.zip and extract to c4dOctane directory if it's not available in place.
There are a few files for each one is for different Cinema4D version. Remove all except the file is for your version.
Ex. if you have Cinema4D R2023, keep only "c4dOctane-R2023.xdl64" and delete c4dOctane-R26.xdl64, c4dOctane-R25.xdl64, c4dOctane-R24.xdl64, c4dOctane-R23.xdl64, etc..
