It's already possible to query certain information inside an HDA file before it's loaded, for example:


will list all "assets" in the HDA, but is it possible to query any other information or metadata? (i.e. Parameter (parm) data)?

I would really like to be able to query parameter info if possible, for example - whether the "basegroup" > "sidefx::maya_component_selection_type" tag exists, and if so, what it's value is (i.e. "vertex", "face", etc...)

If this isn't (currently) possible from an unloaded hda filePath, is there any way to query this info after the hda is loaded and instantiated as an Asset node in Maya?

Apologies if this is already covered in the plugin docs or on this forum, I did look first but didn't find anything.
Thanks

Unfortunately there currently isn't much support for reading data from assets before they have been loaded.

Regarding querying parm tags, we store information about them in attribute categories. You should be able to read the category from the attribute plug:


See here for an example of how we use it internally: AEhoudiniAssetTemplate.mel#L270 [github.com]
