Multiple uvSets from Alembic to Maya Bifrost

I’m importing an Alembic generated in Houdini that contains multiple UV sets. When reading the geometry in Bifrost, I’m not sure how to properly access these UV attributes and expose them as UV sets in Maya.

How can I make the UV sets visible in Maya and usable in shading?
I’ve attached an example of the Alembic data in maya.

set_mesh_uvs seems to work but the uvs are totally scrambled...

Can you post the .abc? or make a repro

I can answer my own question here. The UVs needs to have indices piped into the "set_mesh_UVs".
Had to enable this in the original abc export.

To make the uvSets visible in Maya I found out that you have to convert the bifrost graph to actual maya geometry.
This can be done by right clicking the output node slot and then choose "Create Maya Geometry". Then the multiple uvSet appear in both the set manager and the uv editor.
*Viewport preview works on both (Graph and Maya Geom)
