I am new to Blender (and very impressed).
I have imported a terrain, 3D buildings and roads into Blender using the OpenStreetMap add-on.
The roads are elevated well over the terrain and offset in position.
If z is the altitude, I would like to zero z so that the roads rest on the terrain.
The roads are off in x and y as well. The roads run off the terrain and pass over and directly through buildings.
The default Blender mesh would essentially be underground.
Ideally, I would like to be able to apply actual distances to the Blender model in imperial or SI units and if possible include a light grid throughout a volumetric model.
A possible workflow might be:
- Use OpenStreetMap add-on to import an approximate rendering of the location of interest.
- Correct placement of roads and buildings.
- Apply a scale to the scene in units of miles, kilometers, etc.
I am currently researching 2 and 3.
