Release Notes for Nuke and Hiero 13.2v2

Release Date

31 May 2022

Qualified Operating Systems

• macOS Big Sur (11.x) or macOS 12.x (Monterey). Nuke is currently supported under Rosetta emulation on Apple's new Apple Silicon hardware and M1 chips. Native support is not currently available and Foundry is planning to support the Nuke family natively on Apple's M1 and M2 hardware at a later date.

Article:  For more information on Foundry products and supported macOS versions, see Foundry Knowledge Base article Q100592.

• Windows 10 (64-bit)

• CentOS 7.4 (64-bit), or later

Note:  The currently supported version of VFX Reference Platform includes library versions that are only compatible with CentOS 7.4, or later. Nuke is qualified on the Centos 7.4, 7.5, and 7.6 distributions.

Other operating systems may work, but have not been fully tested.

Requirements for Nuke's GPU Acceleration

If you want to enable Nuke to calculate certain nodes using the GPU, there are some additional requirements.

NVIDIA

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.

AMD

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.

• AMD Radeon PRO W6600

• AMD Radeon PRO W6800

• AMD Radeon Pro W5700

• AMD Radeon Pro WX 9100

• AMD Radeon RX 6800 XT

Note:  For information on the recommended driver for each GPU, see https://www.amd.com/en/support

• On Mac, integrated AMD GPUs are supported on the following Intel CPU Macs:

• Any late 2013 Mac Pro onward (including 2019 Mac Pro),

• Mid-2015 MacBook Pros onward, and

• Late 2017 iMac Pros onward.

All supported Mac Pros include a multi-GPU support option, where applicable. Bitwise equality between GPU and CPU holds in most cases, but for some operations, there are limitations to the accuracy possible with this configuration.

Warning:  Although AMD GPUs are enabled on other Mac models, they are not officially supported and used at your own risk.

Multi-GPU Processing

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.

• ID 504406 - CopyCat: Errors displayed in the Viewer do not disappear as expected during subsequent training runs.

• ID 504191 - Monitor Out: Closing Nuke Studio during playback while broadcasting the timeline Viewer over NDI causes the application to crash on exit.

• ID 504013 - 3D Transform Handles: Negative scaling values in TransformGeo nodes cause inconsistent scaling in upstream ParticleEmitter nodes.

• ID 503687 - Monitor Out: Some controls in the Monitor Out panel in Nuke Studio do not display the knob name in their tooltips.

• ID 503684 - Monitor Out: The Monitor Out panel in Nuke Studio always displays stereo controls, even if the project does not contain multiple views.

• ID 502942 - Monitor Out: The Viewer Monitor Out pane does not display all controls as expected.
As a workaround, resize the pane to cause the controls to appear.

• ID 502843 - Monitor Out: The Use Viewer Gamma / Gain controls are not enabled and disabled consistently between the Properties and Monitor Out pane.

• ID 501261 - macOS Monterey only: Resizing UI elements is slow to update.

• ID 500156 - OTIO: Timelines containing shots with different frame rates displays a warning message incorrectly.

• ID 500138 - 3D Transform Handles: Scaling in Screen space and then rotating in Screen and World space doesn't work as expected.

• ID 499468 - 3D Transform Handles: Handle size is unexpectedly affected by scale changes downstream.

• ID 498754 - Windows only: Nuke occasionally fails to launch due to external hardware connected to the machine.
As a workaround, disconnect any unnecessary hardware such as web cams or additional audio hardware before launching Nuke.

Developer Notes

As Nuke develops, we sometimes have to make changes to the API and ABI under the hood. We try to keep these changes to a minimum and only for certain releases, but from time to time API and ABI compatibility is not guaranteed. See the following table for the situations when you may have to recompile your plug-ins and/or make changes to the source code.

Release Type	Example	Compatibility	Recompile	Rewrite
Version	13.1v1 to 13.1v2	API and ABI
Point	13.0v1 to 13.1v1	API
Major	12.0v1 to 13.0v1	-

Additionally, node Class() names occasionally change between major releases. While these changes do not affect legacy scripts, you may not get the results you were expecting if a node class has been modified. The toolbars.py file, used to create Nuke's node toolbar, contains all the current node class names and is located in <install_directory>/plugins/nukescripts/ for reference.

As an example, between Nuke 9 and Nuke 10, the CameraShake node Class() changed from CameraShake2 to CameraShake3. In the toolbars.py file for the two releases, the entries for the CameraShake node appear as follows:

m.addCommand("CameraShake", "nuke.createNode(\"CameraShake2\")", icon="CameraShake.png")
m.addCommand("CameraShake", "nuke.createNode(\"CameraShake3\")", icon="CameraShake.png")
