Also as a variation to what Marcus suggested, instead of needing to first
capture the assemblies in the scene, do the import, and compare the new
assemblies listing to the old one with a set, you can just pass your list
of nodes to ls() and have it return just the assemblies.
The question is, which list do you pass? The reason for doing a before and
after is getting the difference in order to figure out which nodes were
imported, and which were already there.
Using the Maya Python API:
topLevelDagPaths = list(OpenMaya.bnn_MItDagHierarchy())
OpenMaya.MFileIO.importFile(fileName, type, preserveReferences,
nameSpace, ignoreVersion)return [dagPath
for dagPath in OpenMaya.bnn_MItDagHierarchy()
if not dagPath in topLevelDagPaths]
Which seems to iterate using OpenMaya.MItDag(OpenMaya.MItDag.kBreadthFirst)
It looks like this will return *all* imported nodes, and not just the
assembilies. In addition, finding differences via list-comprehension is
about 100x slower than using sets.
