USD Kind

Blender now has USD Kind export support. If an object in the scene has a custom string property called “usdkind”, its value will be set as the UsdPrim’s kind at export time.

To aid in Kind authoring, a USD Kind panel has been added as part of the Omniverse Panel add-on.

Authoring Kind

Option	Description
Kind	Kind to set on objects. If “custom” is chosen, a field will open up for a custom Kind value.
Set USD Kind	Sets the specified Kind on selected objects.
Clear USD Kind	Clears authored USD Kind value from selected objects.
Set USD Kind Auto	Sets USD Kind on all scene objects based on a heuristic (see below).

Set USD Kind Auto works based on a set of rules. Currently, the only rule applied is to add a “component” Kind to all Empty objects in the scene that do not have parents. We are interested in feedback on other rules to apply.

Exporting Kind

In the USD Export file dialog, there are now options for exporting Kind.

If enabled, objects with authored Kinds will have those kinds reflected in the exported file. There is also a new choice under Default Prim for authoring Kind on the Default Prim at export time.
