We are happy to bring you OctaneRender 2025.2. This new version brings both new improvements and fixes. Thanks again to all those who sent us feedback and continuously help us to improve Octane.
We are tuning OctaneBench 2025 based on this version, and we expect to be releasing it next week.

Important notes:
- The minimum NVIDIA driver version required has been raised to R528 (R572 for GeForce RTX50 Series).
- The minimum version of macOS required is 14.5.
Improvements
- The ray path length can now be accessed inside OSL shaders, with
getattribute("hit:pathlength")
. - OCIO configs up to version 2.4 are now supported.
- Open Image Denoise integration has been upgraded to v2.3.3 (has Blackwell support).
- Added Open Image Denoise quality settings to the "Imager" node and "Open Image Denoise" output AOV node. These let you to choose between fast, balanced and high quality (default) filter modes.
- The Open Image Denoise integration now supports Metal devices.
- Archived OCIO configs (.ocioz files) are now supported.
- Built-in OCIO configs can now be used by using the OCIO URI format instead of a file path, e.g. ocio://default.
- Added a new Alpha render AOV. This contains the alpha channel separately as a matte with white in the RGB channels.
- Allow reversing the order of image tiles along the V axis.
- Added a "scan" button to automatically determine grid size in the image tiles load dialog.
- The file name pattern for selecting image tiles is saved in ORBX and OCS files, so that we can reliably show the correct pattern after loading a scene from disk.
- You can select IOR < 1.0 on every material with dielectric transmission.
- Fixed issue causing RNDR snapshot uploads on to not to be displayed as versions of the same scene on the web interface.
- Fixed possible render engine hang after copying and pasting baking texture nodes.
- Fixed incorrect addition of post processing to beauty pass when alpha channel is enabled.
- Fixed render error when a using high parallel sample counts with NVIDIA devices with over 40GB of VRAM.
- Fixed a bug where render AOV inputs to output AOVs used an incorrect alpha channel if "keep environment" was enabled in the kernel.
- Fixed issue where the decal node's priority and UV transform settings were not applied when connected to an object layer map node.
- Fixed default pin values for OSL inputs for struct inputs which are using function style constructors as initializers. (eg.
vector4 a = vector4(1, 2, 3, 4)
) - Fixed a decal rendering issue when the decal node is configured with six textures.
- Fixed an issue where decals were not rendering correctly on meshes with round edges.
- Fixed some memory leaks on Metal when moving through the timeline.
- Fixed a freeze sometimes when Cryptomatte passes are enabled.
- Fixed a render error that occurs when emission is added to decal wireframe materials.
- Added boolean
allowSquash
property tooctane.gui.PROPS_GUI_LABEL
which allows to stop text from being squashed horizontally before the label starts using ellipsis. - Added boolean
supportedForDenoising
property tooctane.render.PROPS_RENDER_DEVICE
which is set toTRUE
if the device is supported for denoising by Octane. - Added boolean
supportedForRendering
property tooctane.render.PROPS_RENDER_DEVICE
which is set toTRUE
if the device is supported for rendering by Octane.
- The post processing render AOV is now fully opaque, to make compositing easier, since it's a purely additive pass to which the alpha channel is irrelevant.
