Hydra 3D Viewport on Windows & Linux

Introducing the start of Hydra support for Nuke’s 3D viewport. Nuke's new Hydra-powered 3D viewer uses hdStorm as a viewport renderer, enabling a high-fidelity 3D viewport experience that closely resembles the output from the Scanline Render, and provides consistency with other applications using Hydra. In Nuke 13.0, the Hydra viewer is currently available on Linux and Windows.


Support for USD Camera, Axis and Lights

Extending the USD support added in Nuke 12.2, this release adds support for loading camera, light, and axis data from a .usd file via the relevant native 3D nodes in Nuke. This extended USD support enables you to carry the USD data you need directly into Nuke, without converting to a different format. What’s more, these extensions are being open-sourced, so pipelines can further extend and customize these nodes for their specific USD setup. 

Extended Monitor Out

Experience the extended monitor out system in Nuke and Nuke Studio, with a more stable and consistent experience across the Nuke family. This work brings exciting new features into Nuke, including independent output transform controls and support for Nuke Studio’s floating window. Artists can also change the resolution across devices, making it easy to work efficiently across two monitors, and can enjoy a smoother experience when moving between the timeline and nodegraph.

HDR Display on macOS (beta)

First introduced in Nuke 12.2 as a hidden feature, we’ve now enabled the ability to view HDR in the GUI when using an HDR monitor on macOS as a beta feature. Nuke users with Apple XDR or EDR capable monitors or other HDR monitors can now experience the revolutionary benefits of HDR workflows. You can now composite and review in true high dynamic range, across all of the Nuke, Nuke Studio and Heiro viewers. Support is off by default and can be enabled via a Preference.

Collaborate and review remotely with Sync Review

The extended Sync Review offers a new way to collaborate, allowing teams to review together or remotely, working towards the shared vision of the final image. Teams can connect unlimited sessions of Nuke Studio, Hiero or HieroPlayer, collaborate and review projects in context, and sync all the actions needed in a review session, from playback and annotations to editorial changes.

Annotations in HieroPlayer


HieroPlayer now includes the same annotation capabilities as Nuke Studio and Hiero. Artists can create and edit annotations live during a Sync Review session, or when working on their own in a HieroPlayer project.

Machine Learning Toolset

Introducing to Nuke 13.0: a new suite of machine learning tools in NukeX with the CopyCat and Inference nodes. This toolset enables artists to harness the power of machine learning to create and apply their own high-quality sequence-specific effects.

  • CopyCat Node

    The CopyCat node allows artists to train neural networks to automatically complete tasks ranging from garbage mattes, tracking marker removal, beauty work and much more using a small number of reference frames in a sequence, and then training a network to replicate this effect. Input a selection of the original frames, alongside what you want them to look like, and hit ‘train’—it’s as simple as that. 

  • Inference Node

    Inference is a node that runs the neural networks produced by CopyCat. Once CopyCat has successfully trained a network, its weights will be saved in a checkpoint as a .cat file. This can then be loaded in the Inference node and applied to the remainder of the sequence, or even a different one altogether.

New Upscale and Deblur Nodes

Nuke 13.0 includes two new nodes for common compositing tasks, optimized using the ML methodology behind CopyCat and the open-source MLServer. The Upscale node allows artists to resize footage by x2, and offers a GPU-enabled alternative to Nuke’s TVIScale node, while the Deblur node removes motion blur from footage and is ideal for reducing blur from stabilized footage. The Upscale and Deblur models are pre-trained and don’t require Copycat, but they can be used as the basis for further training using CopyCat.

Core Performance

In Nuke 13, we continued building on the work to Nuke’s performance from the Nuke 12 series. These incremental improvements are focused on enhancing Nuke’s ability to utilize hardware, increasing interactivity and processing speed, especially on high numbers of threads. Performance will vary depending on the operating system, but on average:

  • Overall, Nuke 13.0 is up to 10% faster than Nuke 12.2, on both Linux and Windows. Compared to Nuke 11.3, Nuke 13.0 is up to 35% faster on Linux and up to 70% faster on Windows.

VFX Reference Platform 2020

Nuke 13.0 includes support for the VFX Reference Platform 2020, and a major upgrade to its Python API—updating to Python 3.7.7. As of Nuke 13.0, Python 2 support will no longer be available and Python scripts and integrations will need to be updated. Alongside this Python update, Nuke’s other third-party libraries have also been upgraded so artists can stay up-to-date with industry-standard technologies. See the release notes for the full changes in this release.

Native Cryptomatte support

This release introduces a Cryptomatte node in Nuke, allowing artists to read in and work with Cryptomatte data, originally developed at Psyop, without relying on the open-source plug-in. The Nuke native plug-in will be available as an example in the NDK so developers can reference this code for their own customizations and extensions.

OCIO Roles Improvements

The behavior of OCIO roles has been updated to allow artists and teams much greater control. A new option enables users to demote the roles into a submenu. In addition, it is now possible to disable the roles so they will not be displayed, offering the same experience as Nuke 11. This can be managed in the Preferences or via environment variables.

SDK Upgrades

There has been a range of upgrades to Nuke’s SDK support, including ARRI RAW which has been updated to, Avid DNxCodec updated to, and updates to the latest SDK for DNxHR and DNxHD (Mov and MXF) reading and writing. There have also been developments to Nuke’s Monitor out SDKs, including AJA SDK being updated to 15.5.4 and BMD DeckLink SDK to 11.7.
