Hi all,

This is a hotfix for the 1.6 build. Mainly it fixes AOV node connections from dissapearing when loading scenes from older versions
Sadly if you saved your AOV graph with 1.6, it will break in this build again - our apologies for any inconvenience.

To see what the future holds, check out our Trello!

Changes:
  • AOV node connections no longer dissapearing when loading scenes from older pluign versions
  • Fixed RS converted material breaking in certain situations, they now no longer use absolute paths for certain OSL scripts
  • Tab behavior works correctly again in RGB UI on Octane nodes
  • OctaneRender PV: Fixed non responsive/resetting sample count
  • OctaneRender PV: Fixed Infinite hang when denoised beauty is requested when rendering info

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..

I have a chance to update before the next long render, does this fix the render node issue where some of my nodes would fail immediately?

Really excited to try some new C4D 2025.3 features!

Also, can you recommend the best Nvidia driver version with RTX 5090? I'm getting an insane amount of crashes on my main machine after needing to update from stable studio driver 552.22.

There's a little bit of an annoying behavior with the Render AOV Manager saving path.

If there's a project in let's say "J:\Project\ABC\Project.c4d" and you use the standard Save options of C4D with the File set as "$prj". It'll save it in "J:\Project\ABC\Project.exr"
The Render AOV Manager saves it in "J:\Project.exr". Kinda annoying as I generally only use tokens. I need to include the full path to not have it saved it elsewhere.

Any chance we can have that fixed in the next release ?

Thanks, team!
Looks great here so far.
Could you guys please implement the Memory Pool graphic just like Octane Standlaone provides? It is really helpful for 2x3090 + Nvlink Setup.
Been asking for this for over 2 years now, 30xx series still relevant, specially with 40xx and 50xx catching fire with power connectors.
Regards,

Wow... you are right.
Was working till last version.

Sorry guys but I'm not able to reproduce the Denoiser issue in Picture Viewer here, in both Mac and PC.
I've tried both Octane AI Denoiser and Open Image Denoiser, in different file formats, with multi layer enabled and disabled, but Denoised beauty AOV was always saved correctly here.
Could you share an example scene that shows the issue?

ciao,
Beppe

Hi Beppe,
here is a file to test the denoising. But every file will not work since last update.
