export alembic with multiple UV mapping

[mathieu_boch]

Hello, I need help about exporting animated geo in an alembic file.

I use the "birth object" node to create particles, with 3 UVs map channel in source object.
Everything's working fine until the export in alembic which export only the 1st map channel.

I find issue using tymesher, but is there a way to do it with the "Export particles" node ? 
Maybe with the pre-export maxscript ?

Thank you for any answer !

You can try exporting with Max's native Alembic exporter instead....(File > Export)...see if that retains the extra UVWs.

Make sure you add a Mesh operator to your event(s) and turn 'render-only' off, so that Max can see the particle meshes.
