Hi! I model some buildings import from Blender and try to duplicate to many of them. Should I just duplicate from the model or create a prefab of it first? Any differents?
What are you going to do with the duplicates?
just level design, place the building everywhere
I would create prefab from it first.
And than use prefab. I would never use raw model.
That way you can modify it later or even exchange it completely.
