Worth noting that there's a bug where the getAllItems method doesn't
return anything (useful) until the ReadGeo2's properties panel is displayed.
Meaning this does not work:
rg = nuke.nodes.ReadGeo2(file='/path/to/example.abc')
print rg['scene_view'].getAllItems()
..instead it always returns ['------- ']
The only workaround I found is this:
readGeo = nuke.createNode('ReadGeo2', 'file {alembicFile.abc}')
readGeo.hideControlPanel()
sceneView = readGeo['scene_view']
allItems = sceneView.getAllItems()
sceneView.setImportedItems(allItems)
sceneView.setSelectedItems(allItems)
..which works, but does cause the properties/geo to momentarily appear,
and uses the old-fashioned way of setting the file knob (with the 'file
...' Tcl-string argument)
Just reported this to Foundry support (so I have no Bug# yet, although I
suspect it's already been reported)
