Maya USD Import Help

[jcoelho88]

Hello,

I want to be able to import my USD assets with variant selection via python.

When importing with the import dialog there is a option to open a hierarchy view and select the variants on what ever prim you want.

The command pops up in the script editor when its ran but I do not see how any of the options chosen in the Hierarchy view is being applied.

Currently an import command I use could look like this.

cmds.file(
            assetusd_path, i=True, type='USD Import', ignoreVersion=True,
            renameAll=True, mergeNamespacesOnClash=False, namespace=namespace,
            options=";shadingMode=[[none,default]];preferredMaterial=none;primPath=/;readAnimData=0;"
                    "useCustomFrameRange=0;startTime=0;endTime=0;importUSDZTextures=0",
            preserveReferences=True, importFrameRate=True, importTimeRange='override',
        )

How do I include the options for variant selection on specific prims via the python import command?

Any help would be appreciated.

Cheers,

Jason Coelho

Hi @jcoelho88, all the information is stored in a singleton class called ImportData.

That class is not yet exported to the Python API. Would you like to wrap it and submit a PR? See files in lib/mayaUsd/python for Python wrapper examples. See wrapStageCache.cpp for a starting point on exporting singletons.

Hi @JGamache-autodesk . Has there been any updates on this?
It currently seems impossible to choose the variants that get imported when scripting with Python.

Nothing further has been added on this front. Is this something you would still consider trying to help us expose ? I'll make sure it gets added to the backlog or prioritised if it is already there. @tanant, something to followup on.

I wish I could expose it myself, but I don't have the technical skills to compile the plugin.

@erikstantoncarlson @jcoelho88 minor admin - i've just converted this back to an issue (well, made an issue from this discussion) so it's more visible and can be prio'd etc, I think it's better in this case for us to do it as an issue - #2685 - if you want to comment there with any details on what you'd possibly expect that interface to look like or detail i've missed here go for it!

Hello @tanant,

Thanks for making it an issue, I did attempt what @JGamache-autodesk but it was beyond what I was capable of doing. I had issues even building the plugin!

I will be sure to take a look at the new issue.

Cheers,
