Custom Pref name

[ralphmeijerambassadors]

Hi,

For our pipeline we are trying to set a custom Pref name on export but I'm struggling how to do it. Houdini expects the Pref name to be 'rest' for certain tools and I want to make sure every asset being exported from Maya to USD has that primvar. The docs on the export command are mentioning the following:

"Determines how to export reference objects for meshes. The reference object's points are exported as a primvar on the mesh object; the primvar name is determined by querying UsdUtilsGetPrefName(), which defaults to pref. "

This implies you can give a name other than the default Pref. Does anyone have more info on how to do that?

Thanks in advance,

Ralph
