Release Notes for Nuke and Hiero 12.0v8
22 October 2020
Warning: As a result of the current COVID-19 lockdown here in the UK, Foundry is unfortunately not able to perform all of its usual QA tests for Nuke's monitor output, including VR headset support. As such, there may be some reduction in related functionality in this release.
Qualified Operating Systems
• macOS High Sierra (10.13) or macOS Mojave (10.14)
• Windows 10 (64-bit)
• CentOS 7.4 (64-bit), or later
Note: The VFX Platform 2019 upgrade includes library versions that are only compatible with CentOS 7.4, or later. Nuke 12 is qualified on the Centos 7.4, 7.5, and 7.6 distributions.
Other operating systems may work, but have not been fully tested.
If you want to enable Nuke to calculate certain nodes using the GPU, there are some additional requirements.
An NVIDIA GPU with compute capability 3.0 (Kepler) or above. A list of the compute capabilities of NVIDIA GPUs is available at https://developer.nvidia.com/cuda-gpus
Note: The compute capability is a property of the GPU hardware and can't be altered by a software update.
With graphics drivers capable of running CUDA 10.1 or above. On Windows and Linux, CUDA graphics drivers are bundled with the regular drivers for your NVIDIA GPU. Driver versions 418.96 (Windows) and 418.39 (Linux), or above are required. See https://www.nvidia.com/Download/Find.aspx for more information.
Note: We recommend using the latest graphics drivers, where possible, regardless of operating system.
Note: Bit-wise equality between GPU and CPU holds in most cases, but for some operations there are limitations to the accuracy possible with this configuration.
• On Windows and Linux, an AMD GPU from the following list:
Note: Other AMD GPUs may work, but have not been fully tested.
• Radeon™ RX 480
• Radeon™ Pro WX 7100
• Radeon™ Pro WX 9100
• Radeon™ Pro SSG
• Radeon™ Pro WX 8200
Note: For information on the recommended driver for each GPU, see https://www.amd.com/en/support
• On Mac, AMD GPUs are supported on any late 2013 Mac Pro, mid 2015 MacBook Pros onward, and late 2017 iMac Pros.
Warning: Although AMD GPUs are enabled on other Mac models, they are not officially supported and used at your own risk.
Nuke's GPU support includes an Enable multi-GPU support option. When enabled in the preferences, GPU processing is shared between the available GPUs for extra processing speed.
Note: Multi-GPU processing is only available for identical GPUs in the same machine. For example, two NVIDIA GeForce GTX 1080s or two AMD Radeon™ Pro WX 9100s.
There are no new features in this release.
• ID 162824 - OCIOCDLTransform: Nuke now supports ASC (American Society of Cinematographers) .cdl files.
• ID 158957 - Python: Calling undoDescribe() on multiple operations only returned the latest operation.
• ID 439450 - OCIO: Loading certain .ccc files displayed a NameError incorrectly.
• ID 439862 - Timeline Editing: Scrubbing the playhead over uncached frames caused the Viewer to jitter.
• ID 449096 - Deep: ScanlineRender did not produce the same composite results compared to earlier Nuke 12.0 builds.
New Known Issues Specific to Nuke 12.0
This section covers new known issues and gives workarounds for them, where appropriate.
Note: NVIDIA GPUs with compute capability of 3.0 (Kepler) cannot process .r3d files due to a known issue in the R3D SDK preventing decoding and debayering. Nuke defaults to CPU processing when reading .r3d files with these cards installed. A list of the compute capabilities of NVIDIA GPUs is available at: www.nvidia.co.uk/object/cuda_gpus_uk.html
• ID 447820 - Deep: Viewing a DeepMerge node with deep.front and deep.back set to inf values causes Nuke to crash.
• ID 444901 - Deep: Viewing a DeepMerge with DeepFromImage inputs causes Nuke to crash.
• ID 444111 - Deep: Viewing Deep nodes through ScanlineRender output displays artifacts if the scene contains semi-transparent pixels in front of overlapping samples.
• ID 443793 - Referencing sys.argv in the QApplication() function causes Nuke to crash.
• ID 437042 - Windows only: Nuke no longer registers Nuke scripts with an associated program when installed.
As a workaround, install Nuke 11.3v6 to associate scripts, then change the associated file by right-clicking the .nk script and navigating to: Open With... > More Apps > look for another app on this PC to find the required version of Nuke.
• ID 436623 - macOS only: Changing the blend mode during playback causes Nuke Studio and Hiero to crash.
• ID 435284 - Python: Calling nuke.message() or nuke.alert() doesn't wait or pause the main thread as expected.
As a workaround, use QtWidgets:
from PySide2 import QtWidgets
QtWidgets.QMessageBox(QtWidgets.QMessageBox.Information, "Nuke", "Test Message", QtWidgets.QMessageBox.Ok).exec_()
• ID 434043 - Python: The pyside2-rcc component is currently missing from the bundle.
• ID 432839 - Script Editor: Selecting text in the Script Editor output pane occasionally causes Nuke to crash.
• ID 431980 - macOS only: Selecting a shot on the timeline stops the execution of Python in the Script Editor using the Cmd+Enter keyboard shortcut.
• ID 429533 - Windows only: The goofy_title.txt file is missing from the Nuke plugins directory.
As a workaround, copy the file from a legacy version of Nuke to:
• ID 429245 - UI: Using / (slashes) or spaces in path substitutions in the Preferences pads table rows incorrectly, making the UI unusable.
• ID 428360 - DeepMerge: Holdout does not work as expected on volumetric data samples.
• ID 427913 - Monitor Output: Looping a sequence on a monitor out device causes playback to skip frames.
• ID 425201 - Python: Using lambda functions inside a PySide2/Qt Signal currently returns a boolean rather than the argument passed.
• ID 423515 - Windows only: Launching Nuke in --safe mode causes the application to become inaccessible, even though it is running.
• ID 422181 - macOS only: Moving the Curve Editor panel to second monitor displays a blank image.
• ID 420671 - macOS only: Monitor output from AJA cards at 4K / 10-bit causes the playhead to redraw incorrectly and lag behind playback.
• ID 420592 - C_CameraSolver: Clicking Solve occasionally produces different results before and after saving a script.
• ID 420354 - Workspaces: Node panels do not update correctly if the Properties panel is open on a second monitor.
