Is it possible to import entire maps created in blender to unity? When I drag in the blend file for it it considers it a single model and tells me there is too many faces. Also, none of the textures are still in place.
If you create models as separate objects in Blender they load as separate models in Unity. When UV mapping them, load the textures from the Unity assets folder for your project rather than from somewhere outside the project folder. Then the models will load into Unity correctly.
Sorry but you'll need to model everything. If you don't make it into many files you'll have to many faces and you'll have trouble texturing everything correctly.
