I’d like to import a large geolocated region. Except I keep receiving errors on import. Zooming in and selecting a smaller region works just fine. So this leaves me wondering about “stitching” several 3D terrains together.
You can import multiple chunks of terrain. Keep in mind that the model can quickly become bloated due to all the geometry, especially if there is a lot of variation in the terrain.
You could also try an extension like oob terrain - which allows for larger area imports. It comes at a small cost but if you find yourself doing this often then it may be worth it.
