Octane 2026.2 for Cinema4D - v1.8.3
Posted: Wed Feb 11, 2026 12:15 pm
Hi all,
This is the first plugin release for OctaneRender 2026.2.
For this release we continued our focus on stability and quality.
Notably most colors from Octane materials, Redshift and legacy C4D materials should now be in the correct color space.
And colorpickers in C4D should now match with the Live Viewer when the LV is set to the sRGB colorspace.
Additionally we now support the Chinese version of OctaneRender.
Due to legacy issues the plugin itself is a mixed translation for now, and a lot of text will still be in English.
To see what the future holds, check out our Trello!

Some important notes about these builds:
The minimum NVIDIA driver version required is R535 (R572 for GeForce RTX50 series).
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, R2024.5.1, R2025.3.3, R2026.1.2). 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..

2026.2 - v1.8.3 plugin revisions
- Color space handling has been corrected across the plugin for C4D 2024/2025/2026.
- MaterialX import support added (available in the Live Viewer dropdown next to Import ORBX).
- Updated to Octane 2026.2.
- Added Chinese version of the plugin. The translation is not complete yet and will be mixed with English. We will continuously improve the translation.
- GUI inputs for Octane nodes are now displayed in sRGB and match the Live Viewer when the LV is set to sRGB color space.
- The Live Viewer (when set to sRGB) now matches C4D and Redshift when the OCIO view tonemap is set to un-tone-mapped.
- Redshift materials now transfer color values to Octane in the correct color space.
- Legacy Standard materials now transfer color values to Octane in the correct color space.
- Object Layer Color in the Octane Object Tag now has its own dedicated UI matching Octane Standalone.
- Removed support for the legacy linear workflow.
- The plugin now consistently stores color information in linear sRGB.
- Sending a picked color to the Octane Physical Camera Tag is now supported.
- Fixed distorted UVW issues.
- Fixed a crash caused by accessing pixel data outside of the Live Viewer image.
- Added support for User Data tags on child objects.
- Refactored Kernel settings — the UI now matches the Octane Standalone layout.
- Added Radiance Cache to the Photon Kernel.
- Added compatibility mode to the Universal Camera.
- Added compatibility mode to PBR Materials.
