Provides UI and functionality to publish files to Shotgun.
By: Shotgun Software
Latest Version: v0.10.4 (prod)
For our version numbers, we follow the Semantic Versioning standard.
System Name: tk-multi-publish
This document describes functionality only available if you have taken control over a Toolkit configuration. Please refer to the Shotgun Integrations User Guide for details. Multi Publish is a workflow app that artists can use to publish files to Shotgun. The app provides a simple UI on top of a highly customizable core that can be easily configured to publish any combination of files or data from a work scene and it's dependencies (e.g. the Maya scene, Nuke Script, OBJ's, Alembic Caches, Cameras, Textures, etc.). The multi publish app is used in all default configurations and can be easily configured to support workflows ranging from Alembic Cache generation in Maya to render publish in Nuke, art reference management in Photoshop or plate ingestion in the Shotgun and shell environments.
This document describes functionality only available if you have taken control over a Toolkit configuration. Please refer to the Shotgun Integrations User Guide for details.
The main interface is split into three key sections:
Primary Output. Items to be published are organized by their output type with the primary output given prominence at the top of the UI. There must be exactly one item to publish for the primary output which would typically be the scene file itself.
Secondary Outputs. Secondary outputs are optional and there can be as many as required. Items from the scene (e.g. a mesh in Maya) can also be associated with multiple secondary outputs (e.g. OBJ export together with an Alembic Cache export) if needed.
Publish Details. In addition to selecting the items to publish, the interface also allows the artist to choose the Shotgun task (if they haven't already specified this in the current Work Area), capture a thumbnail and add a comment.
When using the app, the artist workflow would typically be:
- Launch the app, select the items to be published, choose the Shotgun task, set the thumbnail, enter a comment and then click 'Publish'.
- The app will perform a pre-publish validation pass on the selected items.
- If there are any problems it will ask if it should continue. If it shouldn't then it will stop and display the problems, allowing them to be fixed before continuing.
- If there were no problems or it was told to ignore any problems, it will then publish all selected items, starting with the primary.
- As long as the primary item is successfully published, the app will finish by running a post-publish step. Typically this is used to version-up the current scene and do any cleanup.
- Finally the result: Success or Failure, is displayed together with any problems reported by the publish step.
Customizing Multi Publish
Multi Publish has been designed to be extremely configurable with all the key steps being implemented as a series of hooks. As well as separating out all engine specific calls from the app, making it easy to configure for new engines, these hooks also provide complete control over the publish process.
These are the main hooks that together comprise the publish workflow:
- hook_scan_scene is responsible for scanning the current scene for items to be published. It should return a primary item together with any number of secondary items.
- hook_primary_pre_publish is typically where you would validate that the primary item can be published. This can return a list of non-fatal problems that won't stop the publish.
- hook_secondary_pre_publish is where the validation of all secondary items happens. Again this can return a list of problems that the user will have the opportunity to fix before continuing.
- hook_primary_publish will publish the primary item for the primary output. Typically this is responsible for copying the current scene file to the publish area and registering it with Shotgun. It should return the full path to the published file which is then passed as a dependency to the secondary publish hook. Raising an exception within this hook will stop the publish and notify the user.
- hook_secondary_publish publishes the secondary items for the secondary outputs. Again this typically exports or copies the published files and then registers them with Shotgun.
- hook_post_publish is the final hook in the publish workflow allowing any clean up to be done at the end of a publish. In the default hooks, this is where the scene is versioned up. This hook will only by run if the primary publish succeeded without raising an exception.
These additional hooks can be used to customize the behaviour of the app.
- hook_thumbnail can be used to provide a thumbnail for the publish in cases where performing a screen capture doesn't make any sense. If this returns a file path to a thumbnail then the screen capture functionality is disabled.
- hook_copy_file is used to do any disk based file copying of files by the app. The default hooks use a utility method on the app which in turn calls this hook. To do this, call
self.parent.copy_file(...)from within the hook.
Outputs & Items
It's important to understand the relationship between the outputs defined in the configuration and the items returned by the scan-scene hook.
Each output has a
scene_item_type property which is an arbitrary string defined by the configuration.
primary_scene_item_type must be unique.
Multiple secondary outputs can share the same
scene_item_type. For example, if the two secondary outputs: 'OBJ' and 'Alembic Cache' are given the same scene_item_type
geometry, this indicates the intention that all geometry items from the scene should have both an OBJ and Alembic Cache file published for them.
Each item returned by the scan-scene hook has a
type which must match a
scene_item_type for one of the outputs defined in the configuration.
The app will combine the list of items with the list of outputs using the mapping between the output's
scene_item_type and the item's
type and present the final list to the user to allow them to select the items for each output to be published.

A Shotgun Snapshot is a quick incremental backup that let's you version and manage increments of your work without sharing it with anyone else. Take a Snapshot, add a description and a thumbnail, and you create a point in time to which you can always go back to at a later point and restore. This is useful if you are making big changes and want to make sure you have a backup of previous versions of your scene.

This application forms the basis for file management in the Shotgun Pipeline Toolkit. It lets you jump around quickly between your various Shotgun entities and gets you started working quickly. No path needs to be specified as the application manages that behind the scenes. The application helps you manage your working files inside a Work Area and makes it easy to share your work with others.
This document describes functionality only available if you have taken control over a Toolkit configuration. Please refer to the Shotgun Integrations User Guide for details. This app contains a custom Write Node gizmo for Nuke, abstracting away the file system paths from the user, allowing them to focus on just naming the particular output. Shotgun takes care of the rest! This app is typically used in conjunction with the Publish app and if you install the publish app for nuke, you most likely want to install this one too!

Welcome to the release notes for this App. 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!
Better handling of unicode file paths during pre-publish validation.
Switches to writing jpg for thumbnails instead of png.
This stops further libpng errors mentioned in v0.10.2 release notes from occurring.
Removes problematic profiles from png files used as icons.
This will silence libpng warnings from Qt when the png files are loaded as pixmaps. This is a second attempt as this profile stripping, and uses ImageMagick's "mogrify" command to achieve the desired result, which maintains color consistency.
Adds support for tk-photoshopcc.
[minor] UI layout tweaks to address further visual quirks discovered during v0.9.5 testing.
[minor] UI layout tweak to address visual quirk in Maya 2017 on Windows.
[minor] Removes log_error call that was in place for debugging purposes.
Properly supports changing contexts on the fly.
Changed default icons.
QA Fix: Verifies that 3ds Max writes the .abc file to disk before publishing.
Adds support for Alembic cache publishing for 3ds Max 2016+.
QA fix to use file base name as part of publish name
QA fix to avoid multiple path matches in output file matching
QA fixes for houdini publish hooks on Windows
Prevents annoying save popup for Houdini
Adds the ability to publish alembic/mantra outputs
Bug fix for Nuke Studio support in the tk-nuke scene operation hook.
Hotfix. Bug in conditional in primary publish.
Adds Nuke Studio support.
Adds user_data argument to hooks for sharing a dict of data between them.
The user_data dict is passed to all hooks when they are executed. This dict is shared across all hook executions and, as such, can be used to store data in within a hook that can then be accessed from subsequently run hooks. Because this is a new argument being passed to each of the hooks, it's possible that custom hooks will need to be updated to accept the additional argument. That being said, tk-multi-publish hooks are all setup to accept **kwargs out of the box, so unless that has been explicitly removed from a custom hook there will not be any problems.
Fix for QLayout warnings on app launch
Merges Hiero hook operations into Nuke hooks.
Changes necessary to allow the tk-nuke engine to work within the Hiero mode of Nuke 9.0+.
Minor fix for a publish item UI error in 3ds Max 2014
throw exception if sending to Screening Room while in proxy mode and misc cleanup
Publishing proxy renders is not supported, this adds additional checks to ensure nothing slips by while in proxy mode in Nuke removed incorrectly named hook files for 3dsmaxplus engine fixed missing import
Fix to unicode strings causing Houdini operations to fail.
Added handling for edge-case crash when publishing channels from Mari
- This change implements a workaround for a rare bug where publishing flattened channels that contain only a single layer could crash Mari.
Adds .psb support in Photoshop.
This release adds Photoshop PSB support. In order to save your Photoshop scenes as PSBs, simply update your
templates.yml file entries for Photoshop (
photoshop_asset_*) to use the extension
.psb. Note that you won't be able to use
.psb at the same time for the same entity type. Also, you need the
tk-photoshop engine's version to be greater or equal to v0.3.0. Finally, you also need
tk-multi-workfiles to be updated to v0.6.7.
Updated Nuke secondary publish hook to use new colorspace friendly method when creating movies for review
- Previously, the colorspace was not being passed through from the Write node so if it was set to a non-default value, the rendered movie would be wrong.
Added support for the new 3DS Max Engine supporting MaxPlus and Max version 2015.
Improvements to the default Mari publish hooks
- Fixed logic to find the next version to use for the published channels
- Mari project is now saved when publish starts
- Folders are now created before files are published
Fixed broken publish paths and names for Mari texture publishes
Fixed issue with Mari publish permanently flattening channels!
Added support for Mari
- Added Alembic publish as a Maya secondary publish
- Added publish hooks for Mari to export texture channels and channel layers
- Items returned from the scan-scene hook that don't match a secondary publish type defined in the configuration are now ignored. Previously an exception would have been raised.
Added Motion Builder support
Updated to use the new framework versioning syntax
- This also requires core v0.14.58
fix error in dependency check in Nuke when read nodes have empty filenames
If read nodes in the current script have their file knob set to
"" by a script, this will return
None when reading the file knob value back which causes an error when trying to replace the path separator. This fix checks to make sure we have an actual (non-empty) file name before continuing on to try and match it with a template. If the
file_name is an empty string or
None, we skip the check and move on error free.
Primary pre-publish errors are now displayed in the UI.
Details: - Previously, the user was informed that there were errors but the actual errors were never displayed - this has been fixed!
Fixed issue when allow taskless publishes was set to False
Details: - Also changed the default back to True for this setting
Various fixes and new features:
Details: - Added a new setting to allow 'No Task' selection for publishes when the current context doesn't specify a task and the pipeline supports task-less publishes. - Added a second per-item progress bar for publishes when there are more than one item being published. - Fixed some issues with the progress reporting where the progress bar wasn't behaving correctly. - Updated hook to use the latest interface.
