Create usd stage from file using python

[raphaeljnwave]

Hi,

I am trying to load usd file in Maya using python (trying to reproduce Create -> Universal Scene Description (USD) -> Stage From File ...) but I only succeeded to convert an usd file into maya object, with no usd stage. By looking the doc, it appears that the -uac argument from mayaUSDImport is what I am looking for, but it does not do the job : cmds.mayaUSDImport( file=path, useAsAnimationCache=True)
Can you please highlight me on this problem ?

Thank you,
Raphael

@raphaeljnwave Have you tried doing this?

shape_node = cmds.createNode('mayaUsdProxyShape')
cmds.setAttr('{}.filePath'.format(shape_node), filename, type='string')

Thanks ! Indeed, I did not thought about creating directly the node :)

Have a look at what

maya-usd/plugin/adsk/scripts/mayaUsd_createStageFromFile.mel

Line 118 in c114b4b

proc string doCreateStage(string $fileName) {

does. We go a bit further and populate some attributes, as well as connect to the time node. It's admittedly awkward that this is only available in MEL, but you could create your own Python function that calls this MEL procedure. Hope this helps.

Yes it will help for sure ! Thanks @ppt-adsk
