We are happy to bring you the stable release of OctaneRender 2025.1. Thanks again to all those who sent us feedback and continuously help us improving Octane.
Important notes:
- The minimum NVIDIA driver version required has been raised to R528 (R572 for GeForce RTX50 Series).
- The GPU version of Open Image Denoise is supported on Volta and Ada GPUs currently. The CPU version is used on devices with other models, and on macOS.
- The minimum version of macOS required is 14.5.
- Rest Attributes: We added support for rest attributes on meshes with animated vertices.
- New Vectron Texture Displacement: Support for texture displacement in Vectron and Volume SDF nodes.
- New Spectral LensFX: Matches the physically accurate measured effects of real world cameras lenses.
- New Chaos Texture System: Overhauled the Chaos texture node with a number of new features and attributes.
- Native Decal Support: New system in core to support easy and efficient placement of surface decals on geometry.
- Render Network Integration in core: The Render Network web service and UX is now available in core as a native window panel.
- Metal-RT: Major speed and memory improvements to hardware acceleration on Apple M3 and M4 devices with scenes using non-triangle geometry.
- Ray step increase factor: Allows to gain speed by decreasing the quality for secondary bounces.
- 11 New blend modes for output AOV layers
- Added support for NVIDIA GeForce RTX50 Series (Blackwell)
- General performance improvements for NVIDIA devices
Rest attributes remove texture shifting/distortion when using a texture projection that is not UV mapped (no UVs on the mesh) on a mesh with animated vertices. When enabled, the projections will use rest vertex positions and normals to calculate the UVW coordinates. Rest attributes don’t change during the animation so the texture mapping remains consistent.
Rest attributes must be supported by the plugin and can be used by enabling
Use rest attributes pin in a projection node with support for it.When importing a geometry archive,
Rest attributes must be enabled in the archive's import settings (e.g. set it to From bind pose for FBX or From animation time for Alembic). From file assumes that the FBX or Alembic file was produced by octane (e.g. exported to orbx via OctaneRender plugin that supports rest attributes).Vectron Displacement
The new Vectron displacement node lets you displace a Vectron or a Volume SDF with an input texture.
It works in real time, at any scale, and is compatible with complex SDF trees or Mesh Volume SDF. You can also use a field texture to limit the area of action.
You can achieve virtually endless detail by stacking noises on top of each other giving you great results at minimal cost.
Spectral LensFX - physically accurate rendering with real world camera data
This version introduces a realistic lens camera which produces aberrations and other effects similar to real glass camera lenses. The effects included are:
- Bokeh
- Optical vignetting.
- Lens imperfections: such as soft focus, soft edges, and barrel distortion.
- Chromatic aberration
Below is a sample image generated using the new realistic lens camera:
Overhauled Chaos Texture System
The Chaos texture node has been updated with the following new features.
- Support for projections other than
Mesh UV. - Use as a normal map with corrected rotation.
- Distort the grid with a texture.
- Distort the grid with an internal noise.
- Seed input controlling the main mapping randomization.
- Tile transform to offset all tiles' rotation/scale/translation.
- Rotation steps on random rotation.
- Option to disable blending.
- Increased max blending exponent.
- Option to colorize the hexagonal tiles for visualization purposes.
Native Decal Support
The decal feature allow you to project textures onto surfaces, adding visual details like dirt, damage or patterns without altering the underlying geometry. Decals are only compatible with mesh geometries.
This feature is primarily designed for plug-ins to implement features such as Unreal's decal system. Most users can achieve desired results by using layered materials instead. We will improve this feature in future.
The way currently works is by overriding specific channel of a material, it is necessary to specify which channel receives the decal by connecting a decal texture node to the appropriate channel.
To help position the decal in 3D, you can use the decal wire-frame, which can be toggled using the decal wire-frame button located next to the sub-sample button under the render viewport in standalone.
Here you can find a sample scene with a simple decal setup:
Render Network Integration in Core
The Render Network service is directly integrated into Octane's core workspace to provide a more seamless experience for users who take advantage of its computational resources. You can dock the new Render Network browser like any other work pane or keep it in a separate window and check your uploaded scenes and render jobs directly from Octane.
Please note that the Render Network integration is only available on Windows and Linux for now.
Metal-RT optimized HW acceleration on Apple devices
This version improves support for hardware acceleration on Apple M3 and M4 hardware by adding support for non-triangle primitives such as hair, particles, texture displacement and analytic lights.
This means that scenes that use non-triangle geometry will be also able to leverage the HW instead of falling back to the software implementation as before. Scenes with large amounts of triangles as well as other primitives will initially benefit most from this approach.
Below is a performance comparison using a synthetic test scene on an Apple M4Pro chip.

Octane Server (Experimental)
The new
Octane server node allows submitting scene to a octane server and obtain result of the rendering by the network. The server can currently be another Standalone app instance or a separate Octane Server app.This is an experimental feature which currently works in Octane Standalone only on Windows and with limited Linux support. To enable it go to
Settings -> Application, enable the Enable experimental node graphs checkbox, press OK and restart OctaneHere you can find a scene with a minimal setup that uses a server instance on the same computer. In order to start the server in a separate instance of Octane Standalone go to
Octane Server -> Start.Changes since 2025.1 Beta 2
Resolved issues
- Fixed spectral textures (e.g. star field) shifting to purple when used in a composite texture.
- Fixed descriptions of render pass nodes with a type input.
- Fixed rendering error when rest attributes were used with vertex displacement

- Fixed wrong UV mapping of 3D procedural textures used as input to a Color to UV node if the output of that node goes to an image texture node projection input.
- Fixed Open Image Denoise not working on Blackwell devices by using the CPU fallback since there's no GPU version available for this architecture at the moment.
- Fixed a bug where exporting multiple AOVs during rendering could produce inconsistent samples per pixel between AOVs.
- Fixed application crash when a Composite Material is used as the base material input of a Layered Material.
- Fixed issue causing the denoiser sometimes not running for complex output AOVs when rendering was complete.

- Added
octane.apiinfo.PROPS_SYSTEM_INFO.driverVersionwhich contains the driver version string (NVIDIA only).
- Bumped maximum and default values for all kernels for "Parallel samples" and "Max. tile samples" pins.

- Removed incorrect error message about dirt when using global texture AOVs with no dirt.
- General performance improvements for NVIDIA devices.
- Display the number of GPU cores next to the device name for Apple devices.
- A new log flag
statshas been added to enable logging of statistics collection. When the flag is set to2, it resets the user's consent, causing the statistics collection consent window to pop up again. - A new log flag
yesStatsDontAskhas been introduced to allow the user to enable statistics collection without being prompted for consent. - A new log flag
noStatsDontAskhas been introduced to allow the user to disable statistics collection without being prompted for consent.
