Just Trying Google Map SDK for Unity...
Steps for install Google map API / SDK :
1/ Get a google map API-Key (its free for 90 days)
2/ Get the unity package here :https://developers.google.com/maps/do...
3/ Import package in your project
4/ paste the API-key
5/ Set Lat/Long of desired location
6/ Run the game and VOILA !
Note : Google SDK API only work when the game is ran so you can't export data to convert it to offline data (or can you ? Leave a comment.)
