Pretty impressive, yes. The importer could use a little more information than
just the "highway" tag, but it's pretty good for a first version.

(I'm forwarding this thread to the legal mailing list, please follow up there)
My understanding is that, yes, 3D models based on OSM data would be under the
OSM's license. This would be the same with both the CC-by-sa and the ODbL
licenses (the 3D model is considered a database).

It depends on lots of technicalities. Right now, with the CC-by-sa license,
everything would be CC-by-sa, including the final movie. I agree with the
people who think that this is a shortcoming of the CC-by-sa license applied
With the ODbL plus Factual info license, things change. Procedurally-generated
content based on OSM data would have to comply with the ODbL, but *not* with
the factual info license (as the procedural content are randomly-generated
buildings, and those are not facts). *If* the 3D models of the
streets/lots/buildings are distributed, they must comply with the ODbL.
And, as a movie is not a database, the ODbL doesn't apply to it. The same goes
for the textures, character models, etc.
