We are progressing through the alpha stage of 2024.1 and there are still a few changes to come. Thank you to all those who provided feedback.
For details on the features added in 2024.1, please see the 2024.1 Alpha 1 release post.
Some important notes about these builds:
The minimum NVIDIA driver version that is required by this version is 522. You can launch Octane with an older driver version, but it will fail to render and it will produce an error message in the log.
The minimum supported macOS version is 14. If you depend on using an older version, please let us know.
Open Image Denoise is supported on CUDA compute model 7 and later, we fallback to the CPU version on machine with older models. On macOS, only the CPU version is supported.
As with all experimental builds, we advise to not use this release for production purposes. We are trying to, but we can't guarantee that scenes saved with this version will be compatible in future releases. Changes are still being made daily.
Changes since 2024.1 Alpha 2
- Fixed "mismatching barriers" error when using NVLink and denoiser when only one device is enabled for denoising.
- Fixed hang when using real time mode with NVLink GPU peering.
- Fixed possible crash when using a scene file if one of the referenced VDB files is missing.
- Fixed incorrect result when using RT hardware acceleration on macOS when the camera is inside multiple volumes.
- Fixed a potential incorrect result with CUDA after changing geometry when the camera is inside a volume.
- Fixed incorrect result on macOS in some cases when the camera is inside a volume.
- Fixed transforms between object space and world space in OSL shaders (eg.
transform("world", "object", P)), when used in input channels of medium nodes connected to volumes. - Reduced system memory usage in cases where the same displacement map is used more than once.
- Resolved a crash occurring when enabling real-time mode on a render with an active OIDN denoiser.
- Scenes with a lot of triplanar maps with all inputs connected to the same texture node, will start rendering faster.
- We now prevent the composite texture "Chromaticity" and "Luminosity" blend modes from producing a bright green result if the chromaticity layer input to these blend modes is black.
- Fixed compute error happening when updating geometry.
- Fixed a crash occurring when a scene was updated while the OIDN CPU version was running.
- Fixed dirt and curvature global AOVs with Environment.
- Fixed large resolutions causing crashes on macOS.
- Reduced mesh data memory usage on macOS.
- Fixed various errors caused as a result of low VRAM availability during the scene compilation.
- Fixed crashes in the file pattern dialog for an image tile node without any files set up.
- Fixed an invalid pin access error when the subsurface color input is not connected on the Standard surface material.
- Fixed a hang during denoising process.
- Fixed crash or render failure in scenes with a mesh node which has invalid material/object indices.
