Octane 2026.5 for Cinema4D - 2.0.0
Posted: Mon Oct 05, 2026 10:30 am
Hi all,
This is our first 2.0.0 release! For the last year an a half we have been working on getting the C4D plugin into better shape.
We worked on stability and usability and worked on filling in many of the gaps in existing features.
Additionally we have worked on refactoring and building new sysems to facilitate faster and more stable development of new features.
We will be releasing these new features in the upcomming 2.x.x builds.
For this build we are starting with Realtime Rendering, Texture Manager Refactor, and Gaussian Splat rendering in the C4D viewport.
Furthermore the build has a new look as we have improved the icons of the LV and many of the Octane scene Objects and Tags.
In the upcomming builds we will releasing improvements and features such as:
Multiple Render Settings(RenderTargets), Improved Picture Viewer Export Settings, C4D Nodegraph support
This build contains OctaneRender 2026.5
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..

2026.5 - 2.0.0 Plugin Changes
- Upgraded to OctaneRender 2026.5
- Realtime mode in Live Viewer (Windows C4D 2026 only)
This feature shares the octane render results as a GPU texture with C4D resulting in a smoother and faster LV
Will be extended with realtime denoising in Octane 2027 giving realtime noisefree results in the LV
For Multi-GPU setups it is required to have both C4D and Octane use the same GPU for the render results - Gaussian splat viewport rendering (C4D 2026 only)
- Icons update for Live Viewer
- Icons update for Objects and Tags
- Texture Manager Refactor
- Liquid velocity vector support
- Gaussian splat loading by plugin
- SPZ format support for Gaussian Splats
- Added Gaussian log type
- Voronoi Fracture fragments now each get their own instance ID
- NRC Online Training and SPP options on Photon, Direct, and Pathtracing kernels
- Fixed anisotropic pins not appearing on material layer nodes
- Fixed error in the log if a Volume Fog object is created
- Fixed Color picker live update issue
- Fixed issue with chinese color space names
- Removed outdated slider types
- Fixed MaterialX UI bug in attribute viewer (Happened on latest versions of C4D 2026)
- Fixed Texture manager mac crash
- Fixed projection node compatibility issues in older scenes. This fixes issues with upgrading to latest plugin version
- Fixed first mesh UV set missing its UVW tag name
- Fixed removed UVW tags leaving their UV set on the Octane mesh
- Fixed image texture output type when switching between RGB, grayscale and alpha images
- Fixed crash in deleteSubApiNodes when a node had no object link
- Fixed warnings/error messages for simulated camera
- Fixed issue with certain OCIO files
- Fixed importance sampling issue
