OctaneRender® 2026.4 [current 2026]

Tue Jun 30, 2026 7:39 am

Hi all,

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.tryDecode to the Lua API.

Improvements

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

Resolved issues

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

Other changes

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
