Release Notes for Nuke and Hiero 12.0v2

Release Date

18 October 2019

Qualified Operating Systems

• macOS High Sierra (10.13) or macOS Mojave (10.14)

• Windows 7 or 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.

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.

• 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.

Multi-GPU Processing

Hiero'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.

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

Developer Notes

Here are the changes relevant to developers. See Help > Documentation from the Nuke menu bar or https://learn.foundry.com/nuke/developers/120/ndkdevguide/appendixc/index.html for more information.

As Nuke develops, we sometimes have to make changes to the application programming interface (API) and application binary interface (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.

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")

New Features

• ID 393974 - Python: A new method, Node.parent(), has been added to return a GroupNode Python object for the current parent Group.
