I also noticed this behaviour when loading a .OBJ file containing a single
mesh. It was split by the loader into a group holding 70 geodes. I think it
might be done so for performance reasons.
To address your problem you could try the following:
- Save each object into a different file, so you at least have a parent group
to manage each object.
- Use the osgUtil::Optimizer in order to see if flags like
REMOVE_REDUNDANT_NODES, MERGE_GEOMETRY, MERGE_GEODES can help you.
