We are excited to bring you OctaneRender 2026.6. Thanks again to all those who sent us feedback and continuously help us improve Octane.
This version is a small update that introduces support for macOS 27 Golden Gate as well as some fixes and small features.
Important notes:
- The minimum NVIDIA driver version required is R555 (R572 for GeForce RTX50 series, R615 for RTX Spark).
- Supported macOS versions are 14.5 to 27.
Changes since 2026.5
New features
- Added support for macOS 27 Golden Gate.
- Added support for user-specific unattended authentication, which takes priority over system-wide settings.
- Windows
%APPDATA%/OctaneRender(user-specific)%PROGRAMDATA%\OctaneRender(system-wide)
- Linux
~/.OctaneRender(user-specific)/etc/OctaneRender(system-wide)
- macOS
~/Library/OctaneRender(user-specific)/Library/OctaneRender(system-wide)
- Windows
- USD Support
- USD importing of lights that use Blackbody emission is now at parity with non-Blackbody emissions.
- Added support for USD importing of DomeLight_1 and of image textures used in RectLights.
- Added support for USD Import of DistantLight.
- Improved USD import by handling color spaces of textured light images.
- Improved the Greyscale Image node to support color output for re-tinting purposes, and automatically applied the color setting when loading scenes saved prior to version 2026.1.
- Improved undo and redo functionality for grouping and ungrouping node graphs to preserve the selection state during operations.
- Improved MaterialX import settings to enable Fake Shadows by default, allowing direct light to pass through transmissive materials.
- Directional light can now have angles up to 180 degrees if typed explicitly.
Resolved issues
- MaterialX
- Fixed crash on macOS when connecting MaterialX HexTiledImage or HexTiledNormalMap nodes to derivative-taking nodes like MaterialX Bump.
- MaterialX Image nodes using UDIM file paths now extract tile numbers more reliably and properly place rightmost UDIM tiles (1010, 1020, 1030, etc.).
- Fixed import errors when using unsupported MaterialX nodes from USD files, now completes with empty materials and optional warnings enabled via a project setting.
- Fixed missing connections when ungrouping a node graph with direct input-to-output links.
- Improved handling of unconnected input linkers by converting them into expanded nodes to prevent accidental deletion.
- Fixed
Dx(pow(a, b))in OSL to correctly handle cases where the base (a) is zero. - Fixed displacement map import for OpenPBR materials from MaterialX and USD files.
- Fixed improper undo behavior when ungrouping a node graph containing linkers not connected to external nodes.
- Fixed rendering errors on macOS when using OSL shaders with local array variables that have non-zero differentials.
- Fixed an issue where untextured RectLight nodes failed to import correctly from USD files.
- Fixed unpacking of ORBX packages containing imported USD content by ensuring proper organization of files during packaging.
- Fixed missing animation of hair thickness, UV coordinates, and subdivision surface sharpness when loading scenes from Alembic files.
- Fixed an issue where adjusting texture displacement settings on skinned meshes could cause incorrect skinning deformation.
Other changes
- Changed MaterialX displacement import to use the default High displacement quality mode.
Lua API
- Added function
octane.nodegraph.getAssetPaths()that gathers the file paths of all file assets used by a node graph and its owned node items.
