The OpenStreetMap importer is no longer available, All of it's functionality, including automatic OSM downloads, (and a lot more) are available in DEM Earth.
Here is a small list of popular OSM servers.
- Openstreetmap.org For small areas.
- MetroExtracts For City Sized Extracts.
- Geofabrik For Huge country sized extracts
- BBBike Extract whatever you like.Max 768mb
You need to get OSM.XML files from these servers.
gzip,7z,bzip,ect,ect just defines the compression type of the file you receive.
IMPORTANT: you will need to rename downloaded XML files to OSM, by simply changing the file suffix.
e.g. myfile.xml should be myfile.osm
You then simply drag and drop "myfile.osm" into c4d and the openstreetmap importer will convert the file to splines for you.
