Octane 2027.1 Alpha 3 for Cinema4D - 2.0.1 - Alpha Release
Posted: Mon Oct 12, 2026 3:53 pm
Hi all,
This is a build for fixes for the release of last week.
For the stable version of 2.0.1 look here: Octane 2026.5 - 2.0.1
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 2027.1 Alpha 3
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..

Known issues:
- MacOS support will come later
- Material Pick can freeze the plugin
- Due to a bug in Octane we have temporarily turned off material previewing for materials that have an active Sheen
- Added Switch Nodes for all supported nodetypes
The Texture switch menu entry now creates the new node. The old switch texture still loads in existing scenes. - Added Cell noise, FBM noise, FBM flow noise
- Added UV tiling and offset, Look-at transform nodes
- C4D MCP Support.
This consists of a lot of invisible changes to make various features visible to the C4D MCP. This also improved feature visibility to python scripts. - Octane Shader nodes can now be created from a script by setting OCTANE_NODE_TYPE
- Realtime LV now works with Multi-GPU setups by force-switching octane to use the same GPU as C4D is using.
When disabling Realtime LV, the plugin will switch the main GPU back to the original setting - Fixed Shift+R crashing when the Octane plugin was in realtime mode.
- Copy to Clipboard and Show in Picture Viewer now work in realtime mode.
- Centre snapping while panning no longer missing in the Live Viewer in realtime mode.
- Render resolution and viewer zoom now behaves the same in realtime mode.
- The Live Viewer no longer looks blurry with realtime turned off.
- Changes to Linked materials now update the LV
- The “Create Vectron Cone” command was labelled “Create Vectron Tube”.
- The Texture Emission “Keep instance power” pin was sent with the wrong type.
- Fixed C4D particle motion blur regression
- Octane 2027.1 Alpha 3
- Added Vectron Bake SDF to mesh object with baking volume size, offset and rotation (viewport box and handles)
* This node type will change in the future - Added polarization filter (intensity, rotation) to the thin lens, universal and realistic lens cameras
- Added real-time denoiser quality mode to the camera tag imager
- Added visibility cache to environment objects (Daylight and Texture environment etc)
- Added MaterialX material MxSurface
- Added Physical Optics Material
- Added OpenPBR 1.2 (specular haze, retro-reflectivity, emission weight) - older scenes stay on OpenPBR 1.1
- Added Retro-reflective materials and layers
- UV sets go up to 10 now
- Added UV set input to texture displacement for high quality UV atlas baking
- Added baking mode display (UV atlas / Normalized UV) to texture displacement
- Added Burley diffuse BRDF - BRDF model lists now come from Octane (diffuse layer also gets Oren-Nayar energy preserving)
- MaterialX BSDFs can be used in material layer slots, and material layers in MaterialX inputs
- Added realtime denoise setting
- Added opacity pin to baking texture
- Added emission to null material
- Added baking texture
- UVW Vertex Attribute projection
- Fixed retro-reflective toggle not sent correctly on the standard, sub and layer materials
- 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 a node had no object link
- 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
