Release Notes History

The Shotgun engine for Alias Autostudio and Alias Surface & Design establishes a bridge between the Shotgun Pipeline Toolkit apps and Alias. It also contains a PySide distribution, designed to connect QT inside Alias. This makes it possible to write apps, using Python and PySide, that run inside the engine.

Supported Application Versions

This item has been tested and is known to be working on the following application versions: 2019, 2020. Please note that it is perfectly possible, even likely, that it will work with more recent releases, however it has not yet been formally tested with these versions.

Overview Video

The following video gives a quick overview of features and functionality.


The Shotgun engine for Alias contains a standard platform for integrating Shotgun Apps into Alias. It is lightweight and straight forward and adds a Shotgun menu to the Alias menu.

Information for App Developers


The Shotgun engine for Alias uses a PySide installation shipped with the Shotgun Desktop and will activate this whenever this is necessary.

Alias Project Management

Whenever the Shotgun engine for Alias starts, it will set the Alias Project to point at a location defined in the settings for this engine. This means that the Project may also change when a new file is opened. The details relating to how the Alias project is set based on a file can be configured in the configuration file, using the template system.

Working with tk-alias

This Shotgun integration supports the Alias application family (Concept, Surface, and AutoStudio).

When Alias opens, a Shotgun menu (the Alias engine) is added to the menu bar.

File Open and Save (tk-multi-workfiles2)

Use the My Tasks and Assets tabs to see all your assigned tasks and browse for assets. To the right, use these tabs to view all files, working or published files associated with what is selected to the left.

Snapshot (tk-multi-snapshot)

Snapshot: Opens the Snapshot dialog to create a quick backup of the current scene.

Publish (tk-multi-publish2)

Publish: Opens the Publish dialog for publishing the file to Shotgun, which can then be used by artists downstream. For more information, see The Publisher. 

Loader (tk-multi-loader2)

Load: Opens the Content Loader app, along with instructional slides explaining how it works.

Scene Breakdown (tk-multi-breakdown)

Scene Breakdown: Opens the Breakdown dialog, which displays a list of referenced (WREF References) content, along with what in the scene is out-of-date. Select one or more items and click Update Selected to switch and use the latest version of the content.

Installation and Updates

Adding this Engine to the Shotgun Pipeline Toolkit

If you want to add this engine to Project XYZ, and an environment named asset, execute the following command:

> tank Project XYZ install_engine asset tk-alias

Updating to the latest version

If you already have this item installed in a project and you want to get the latest version, you can run the update command. You can either navigate to the tank command that comes with that specific project, and run it there:

> cd /my_tank_configs/project_xyz
> ./tank updates

Alternatively, you can run your studio tank command and specify the project name to tell it which project to run the update check for:

> tank Project XYZ updates

Collaboration and Evolution

If you have access to the Shotgun Pipeline Toolkit, you also have access to the source code for all apps, engines and frameworks in Github where we store and manage them. Feel free to evolve these items; use them as a base for further independent development, make changes (and submit pull requests back to us!) or simply tinker with them to see how they have been built and how the toolkit works. You can access this code repository at

Release Notes

Welcome to the release notes for this Engine. Below you will find an overview of all the changes we did for each release. We try to be as detailed as possible and include all bugs we have fixed, features we have added and things that may have changed. If you have questions about a particular release, don't hesitate to contact our support team!


Official Support for Alias 2020.3

Import Notes:

  • Adding LMV will require a new framework tk-framework-lmv.
  • Creating a 3D Version from VRED will now use the sg_uploaded_movie field. If you are using the legacy 3D viewer you will need to modify the field name to continue using it.
  • Upgrading to this engine version will require tk-core version of at least 19.3.


  • For OBJ, TSM, F3D, SF3D file formats, allow to Import Subdiv via the Loader. (available in Alias 2020.2 and newer)
  • Improve Alias auto-discovery logic and allowing for overrides of your Alias install path using the Software entities
  • Add Alias Publish hook that creates a Version that can be 3D or 2D with a boolean flag
  • When creating Variants as Notes on Publish, fill both the thumbnail and the attachment fields on the Note entity to improve viewability
  • Included a "Shotgun Legacy" plugin for Alias versions older than 2020.2
  • Create the Upstream and Downstream dependencies when publishing files from Alias
  • Adding "Translator Settings" in the "Publish Translation" when publishing from Alias allowing a studio to choose the default to include the user description on all Published translated files

Fixed Bugs

  • Do not loop through Alias Variants when opening the Publisher Dialog
  • Fixed crashing when opening on a new stage
  • Support publishing many variants
  • Publishing a lot of variants doesn't work in Alias?
  • Publishing variants would fails if no Version was selected by the user. If no Version is created, the Notes are only linked to the Published File. Otherwise, they are linked to both the Published File and the Version
  • Thumbnail will now show the user selected screenshot instead of the whole viewport
  • Incorrect Shader when Publishing thumbnails for Alias Variants


Fixed Bugs

  • Fixed backwards compatibility for Alias Shotgun Plugin


Fixed Bugs

  • Context lost after loading a file in a newly created file.

  • Fix the way we get the translator path for backward compatibility.

  • Move the collector logic from tk-config to tk-alias engine
  • Create the publish2 plugins for tk-config-basic

Fixed bugs:

  • Fixed a bug related with context switching when user wanted to save a file outside Shotgun.


  • Fixed a bug in the menu where snapshot and snapshot history were launching the same app.

  • Fixed a bug with the plugin in fresh installations. This was ocurring when a python 2.7.X is not installed on the machine or the PATH environment variable doesn't contain a python executable folder.


Whats New:

With this major release we have added a new communication framework to improve the overall speed and resiliency between Alias and Shotgun. We have also addressed some cleanup and consistency with the rest of toolkit and fixed some customer bugs.


  • Replaced Alias communication protocol with Shotgun using pybind11 library
  • Remove dependency of tk-framework-atf
  • Make tk-framework-locking an optional dependency
  • Change hooks from tk-multi-breakdown, tk-multi-loader2, tk-multi-snapshot, tk-multi-workfiles2 and tk-multi-shotgunpanel to match existing Shotgun tk-default-config2 hook structure

  • Improve Publish Hooks to support when publishing to a permission restricted directory
  • Remove "Import into a New Scene" action in tk-multi-loader2
  • Linked Task to Notes when publishing annotations and variants from Alias

Fixed Bugs:

  • Fixed some bugs related with the locking framework:
    • Unable to save file to Shotgun after publishing
    • Opening a file in Alias fails if using default file_usage_hook
