We are excited to bring you OctaneRender 2026.4. Thanks again to all those who sent us feedback and continuously help us improve Octane.
This version includes a number of fixes as well as improved support for Gaussian splats and Neural Radiance Cache.
Important notes:
- The minimum NVIDIA driver version required is R555 (R572 for GeForce RTX50 series).
- The minimum version of macOS required is 14.5.
Changes since 2026.3
New features
- Added support for MacBook Neo
- Added support for SPZv4 Gaussian splats
- Added support for Neural Radiance Cache (NRC) on macOS (requires macOS 15+)
- Added support for network rendering with NRC
- Added support for importing UV vertex attribute names from FBX material data if no Octane material data is present; set UV set index if it is one of the Octane-specific UV names used for those
- Added
octane.json.tryDecodeto the Lua API.
- Added prompt to select images if the source files are not found for tiles and UV tiles
- Reduced GPU memory usage for Gaussian splats
- Improved reproduction of complicated node graphs when importing FBX with embedded Octane OCS material data
- Added ability to import from and export to FBX planar UV mapping type
- Fixed CUDA error when rendering huge Gaussian splats (30+ million primitives)
- Fixed invalid attribute ID log message when selecting a new file for a texture file name input on an OSL node
- Fixed network rendering with Vectron nodes
- Fixed occasional crash when loading a scene with a lot of meshlets or virtual textures
- Fixed an issue where USD geometry was not correctly connected with its material
- Fixed bug in loading PLY files with spherical harmonics degree 4. Octane currently supports spherical harmonics up to degree 3
- Fixed bug that extra spherical harmonics loaded from .PLY files could be incorrect
- Fixed crash when rendering PMC kernel with small resolution (e.g. 1x1, 1x2)
- Fixed incorrect loading progress values when loading large scenes
- Fixed potential application crash during startup
- Fixed render failure in scenes with post-FX light beams after resetting devices due to a device selection change or in multi-GPU setups
- Fixed issue where Octane stole focus while running a Lua script every time it loaded a new scene
- Fixed artifacts in caustics cast by objects with normal maps based on height maps
- Fixed issue preventing splash screen from showing sometimes on macOS
- Fixed issue causing files to get locked when nodes were copied to the clipboard
- Fixed issue preventing ORBX files from being opened on macOS when double-clicking on them
- Fixed issue where vertex displacement updates were not triggering render updates when connected to a vertex displacement node
- Removed unnecessary logging displayed occasionally with some NVIDIA driver versions
- Changed Mesh UV using UV set 1 to be translated to the UV name "default" in FBX files, matching the default value documented by the format
