Add USD export with USD asset contribution workflow with e.g. model product type

[BigRoy]

Is there an existing issue for this?

• I have searched the existing issues and added correct labels.

Please describe the feature you have in mind and explain what the current shortcomings are?

Allow publishing a model product type with USD output file that also gets published with the USD contribution workflow in a USD asset.

Suggested implementation?

We either add a completely new creator - separate from the existing one - that is of product type model but also marks itself relevant to the USD contribution workflow by adding the usd family to the instance. Or, somehow mark the existing model creator to "optionally" allow to do that. The question mostly becomes what we need.

1. Should the singular "model" instance be capable of publishing the mayaScene, abc (alembic) and usd all at once? If so, we should somehow be dealing with one creator that exports the multiple things.
2. Should the USD creator have the pre-create "Create Asset Template Hierarchy" feature which makes it much easier to define the correct asset hierarchy to work within in the scene (like creating the correct groups with correct names, etc.)
3. Currently the Maya USD creator exposes a lot of the export toggles (how the USD file get extracted) as creator attributes, however some may also turn relevant for this model instance.
   • Hence, we need to either move those also to Creator attributes for the existing model creator (clutter?) OR use the new creator to expose those attributes (redundant duplication?) OR move those export settings maybe to the Maya USD extractor plug-in as attribute definitions OR to a dedicated collected. It will be relevant however to set different defaults for different Maya USD exports, e.g. a model is static and may need different export settings than an animation or a 'generic' maya USD extraction. How/where do we then define these defaults for each in settings? profiles?

I'm mostly concerned with:

• What if the particular product type or creator requires different defaults for extraction? Do we suddenly need profiles filtering and settings everywhere to define defaults? E.g. the stripNamespaces toggle on the Maya USD Extractor. An example of 'different defaults per product type' is also shown here: USD contribution: Set up different default values based on profiles ayon-core#973

Some quick prototypes:

• Export USD with USD contribution workflow using existing 'model' creator #206
• Expose Maya USD creator that creates a static model product type #205

Basically we have a case of:

• This 'model' product should now also behave as 'usd'
• This product type may also benefit from different "creation" features (like the asset template hierarchy creation)
