The main change for this build is C4D R2026 support.
For the rest we focussed on fixes and UI cleanup.

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..
