Need help with importing models at runtime.

Unity Engine
1

I have a code that loads prefabs from folder like this :

void InitAddableObjects ()
    {
        addableObjects = Resources.LoadAll<GameObject>("LevelObjects/");
        if (addableObjects != null) {
            foreach (var item in addableObjects) {
                string tag = item.tag;
                if (!tag.Equals(startPointObjTAG)) {
                    item.tag = addedObjTAG;
                }
            }
        }
        else {
            Debug.LogError ("No objects!");
        }
    }

All these prefabs are created in Editor.
I need to find a way to add more objects (from .fbx files) there at run-time but I don’t have a slightest clue on how to do that. All the objects are random furniture models and nothing else.

There is no runtime importer built into Unity. You will have to look for external implementations. There are a couple of obj and dae/collada implementations out there that work with unity. Fbx ones I have yet to discover.
