multiple prims selected, getting their prim paths

[sanders3d]

So I'm trying to get multiple selections working, and not sure how to go about it. What I'm after is to let the user select a bunch of references and the run a hypothetical command which is "replace with last selected". That way they could start doing layout with a random usd asset and later replace them with actual assets.

So far I'm only able to find 1 selection, t doesn't seem to support multiple selections.

import mayaUsd
from mayaUsd.lib import proxyAccessor as pa

stageShape, primpath = pa.getSelectedDagAndPrim()
stage = mayaUsd.ufe.getStage(stageShape)

print(primpath)
prim = stage.GetPrimAtPath(primpath)

Again, any pointers would be helpful

best regards
stefan

So I finished the tool. It was horrible to find information or docs how to do it. I'm sharing it here and hope that someone can make my tool a bit nicer and with better ( read: pretty ) code.

import mayaUsd
import ufe

def replace_ref():
    #replaces references with the last selected reference
    selection = ufe.GlobalSelection.get()
    rawItem = selection.back().getRawAddress()
    prim = mayaUsd.ufe.getPrimFromRawItem(rawItem)
    main_usd_file = prim.GetPrimStack()[1].layer.identifier
    for item in selection:  
        rawItem = item.getRawAddress()
        prim = mayaUsd.ufe.getPrimFromRawItem(rawItem)
        primpath = prim.GetPrimPath()
        usd_file= prim.GetPrimStack()[1].layer.identifier
        if not usd_file == main_usd_file:
            prim.GetReferences().ClearReferences()
            prim.GetReferences().AddReference(main_usd_file)
