Exporting Groups

Since release of GroupPro 3.0, groups are now represented as empty mesh object + Instance modifier. This mean exporting of groups changed:

  1. Fbx export won't work with new mesh groups directly. Instead, you can use Dissolve, to split grouped objects, then export the flattened hierarchy. After export, you could undo the dissolve to get back the groups.

Dissolve Group Use: MaxDept: 0, Use Empties Hierarchy: True

  1. Alembic - works ok with new mesh groups. Uses mesh child-parent relations, to recreate nested group hierarchy,
  2. USD - works ok. Exported group will use empties child-parent hierarchy

In general blender dose not like the dissolve to much (can crash randomly ). So I would use Alembic, or USD
