Blender mesh part names

[sleekdigital]

I would like to use the Match by mesh name feature when baking my maps in Painter.  My model is in Blender.  Where will Painter need my mesh part names to be?  Vertex groups?

Probably you already have found the way days ago... anyway i rename the mesh/object from the object properties tab.
Low poly object with the suffix   _low   and high poly with suffix    _high . Then export low poly objects all together as fbx/obj, same thing for the high poly ones.
