options to retrieve selected layer name in the mayaUsdLayerEditor ?

[voidreamer]

Hi all, I'm looking for a way to retrieve the current selected layer name (identifier) in the mayaUsdLayerEditor, I didn't see a flag for it in the cmds.mayaUsdLayerEditorWindow command, also the same to change layer selection by passing a layer identifier.
thanks!

Hi @voidreamer

If I'm understanding the question correctly you are asking to get the stages current EditTarget.
The EditTarget is the layer you can see selected via a blue circle in the mayaUsdLayerEditor.

To get the selected layer and its identifier you could run something like this in a python tab on the Maya script editor.
Also to switch the layer selection you can use stage.SetEditTarget(), this works so long as you know the path to the layer you want to switch to.

import mayaUsd
from pxr import Sdf

maya_stage_node_list = cmds.ls(type='mayaUsdProxyShape', long=True)
stage = mayaUsd.ufe.getStage(maya_stage_node_list[0])

# Get the current edit target
edit_target_layer = stage.GetEditTarget().GetLayer()
print(edit_target_layer.identifier)

# Switch to a different edit target
new_layer = Sdf.Layer.FindOrOpen('/PATH/TO/LAYER.usd')
stage.SetEditTarget(new_layer)

Hope that answers the question.

Cheers,

Hi Jason, thanks for your answer,
I was looking rather for the selected layer item from the tree view on the Usd Layer Editor, like in this case the lyr3
for now I made a hacking way to get it by querying the qt pointer.
some times the edit layer is not the selected layer.
