Unity .obj import is regrouping sub-objects
Hello everyone,
I have a .obj file representing a map (generated by OSM2World) and containing multiple sub-objects as Bench, Bridges, Buildings... These sub-objects have the following naming convention : ObjectName+index. Here is an abstract from the file :

When I import it in a Unity project, the ObjectNameX sub-objects are "abstracted" as a single "Building" object :
When I open it in Blender, I have the expected result (multiple ObjectNameX objects) :
Any ideas to avoid this behavior ?
Thank you for your help.
