Pyblish

Pyblish let’s you create content pipelines, and is aimed at VFX & games.
It’s a plugin based system, that’s dcc independent, so you can use the same pipeline in different apps, such as max, ,maya, Blender, substance, …

It’s great especially for validation, so artists can run the tool and it will tell them what’s wrong with their file.

Pyblish is created around the concept of plugins:

• collector plugins collect instances, which are saved in the context
  (e.g. collect meshes)
  why use instance collection in validation
• validator plugins validate instances
  (e.g. the mesh has no n-gons)
• extraction plugins export instances
  (e.g. export the mesh from dcc to disk)
• integration plugins handle various integrations
  (e.g. update Jira or the CMS for the mesh)

The plugin workflow is very powerful, allowing for the creation of a more modular pipeline. Whereas the traditional gamedev pipeline is often unique for each studio and hardcoded to the project, making it hard to reuse.

Limitations¶

• Pyblish has it’s root in the VFX industry, so some parts make less sense for gamedev.
• It’s maintained by only 1 person, Marcus. Who’s not actively working on it anymore.
• My studies on the limits of Pyblish: Pyblish issues

my notes¶

• proposed feature:
  • Pyblish marketplace
  • adaptors

Backlinks¶

• Avalon
  • a more feature rich successor to Pyblish
• Pyblish marketplace
  • how would you make a marketplace for Pyblish
• Pyblish plugin manager
  • Pyblish plugin manager is a python module that let’s you explicitly set Pyblish plugin settings.
• datafix
  • A validation Python API, aiming to address the limitations of Pyblish in a gamedev pipeline
• Pyblish default plugins
  • Pyblish registers some default plugins to get you started, great for starters but annoying after a while since you have to explicitly deregister them every time.
• Pyblish issue - warning vs error
  • Pyblish saves errors and warnings in different locations.
  • Plugins either succeed or fail. There is no soft fail.
• Pyblish simple
  • A UI for Pyblish, aimed at artists. To address that Pyblish issue - UI is not artist friendly
• my code projects
  • various Pyblish repos, WIP - abandoned , PAC will replace them
• Pyblish issue - dependency injection

  • Pyblish dependency injection¶

  • This feels unpythonic
    The implicit nature of this makes it hard to understand and debug.
• Pyblish issue - docs are confusing

  • Confusing Pyblish docs¶

• Pyblish pros
  • I have a love hate relation with Pyblish. I’ve learned a lot working with it. Gave back several contributions to the various projects, and actively contributed to the forum.
    I created a long-term plan to improve Pyblish on the forum
• Pyblish to port
  • Pyblish
  • Pyblish repo collection
• Python outside Python path
  • Pyblish
• lack of open source in the games industry
  • the closest system I’ve seen is Pyblish
• review pac
  • The original goal was: create Pyblish but better, since PRs to fix it didn’t work out. I was bothered by all the Pyblish issues so decided to restart from a clean slate.
