Here’s some that I’ve used for various circumstances.
1. A string attribute, with optional content
- The attribute name itself can be an identifier, such that you can
leverage the wildcard of ls, e.g. cmds.ls("*.mySpecialIdentifier")
- Or, the contents of the string can be an identifier, e.g.
cmds.getAttr("someNode.id")
== "mySpecialIdentifier". In this case, it’s a little harder to
find/list all that match but can offer a little more generality. Roy over
at Colorbleed once put together a fast equivalent of the
wildcard approach
but for the contents of strings here
<https://github.com/getavalon/core/blob/6a2c8edec2fc5cd018d0496d094f8885cde8060c/avalon/maya/lib.py#L400>
that mimic the interface for MongoDB queries, which has worked well. E.g.
to return all nodes with a special identifier, lsattr("idAttribute",
"uniqueIdentifier")
2. An object set. An object set in Maya is the equivalent of a list in
Python and can “contain” nodes by having nodes connected to it. Listing
associated nodes is then made via cmds.sets("mySpecialNodes", query=True).
An advantage of this is that you can get a visual indication of which nodes
are included, along with being able to add elements of e.g. meshes that
aren’t as good with metadata themselves. A disadvantage is the somewhat
invisible behavior of duplicating member nodes and sometimes unhelpful case
of having a lot of members.
Then there’s the somewhat new metadata, but I’ve never managed to penetrate
the documentation enough to actually get this working predictably. It seems
like a good fit though, especially as it can store metadata not only in
nodes but in the scene itself.
