MAYA-107424 - On stage AE template load/reload a file as stage source #1218
Conversation
… as the stage source * Added debugging messages to template helpers (controlled from var). * New template helper method to deal with file path being changed from text field and file browser button. * New template helper method to refresh file path attribute. * Replace file path attribute with custom control containing: label, text field (for path), file browser button, file refresh button.

Pretty awkward that there is no way to do this from Python. Certainly getMayaUsdString() isn't doing much, and
https://git.autodesk.com/maya3d/maya/blob/master/Maya/src/OpenMaya/Commands/getPluginResource.mel
isn't doing much either... I guess we can just leave it as you have it, not a big deal.

I looked at the MEL procs for register/get string resources and unfortunately they don't have python equivalents. But they are trivial, so I've implemented a python version of them in our plugin and now no longer need the mel.eval.

Do we have the filter tokens available in Python? e.g. UsdMayaTranslatorTokens is what we use in c++ when we need filters like this.

I see those in the C++ code, but I don't see anywhere they are wrapped into python. I also checked the USD repo and in their python code they just use the actual strings.
… as the stage source * Created system to register/get localized strings from python. Used that in the AETemplateHelpers file.

Identical to the ones in the MEL file (of the same name).

| register("kButtonNo", "No") | ||

These are the strings that are used exclusively from python. But they can also be loaded by MEL.

Python ports of the MEL procs from Maya.
