Let's take a moment to talk about the 10.000 feet view of Pyblish.
Besides plug-ins, there are two primary objects that are of interest to you.
Context
Instance
The Context
represents the world, typically your current working file, and contains 1 or more Instance
.
You can think of Instance
as a subdivision of Context
, each pertaining to a specific area of the bigger picture, such as an image sequence or a model. When publishing, you can choose to consider either the world or part of the world.
In some cases, it makes sense to only look at a small portion of a working file, either for precision or special treatment. For example, if your Context
is a scene from Star Wars, you might treat Luke different from how you treat The Death Star.
In other cases, it makes more sense to look at the world as a whole, such as when identifying Luke midst other assets in your scene.
Cooperation
Now that you're able to write, register and coordinate plug-ins, it's time to look at how to make them cooperate.
You can use this object to pass information from one plug-in to another. The Context
is also accessible from the return value of publish()
.
