Hello there, my name is Olivier, I'm a kind of CG director and this is my first post here. Please, forgive the noob questions :)
Let me introduce in a few lines why I'm here,

For a small advert I should start soon, I'm currently evaluating Cityengine (Trial).
I think I will end buying Cityengine Basic version (for money reasons, my budget beeing pretty tight on that advert).

The sequence I have to do is a wide top-shot view of a french-like city. The camera will be high up, covering 3-4km lenght of a city. The shot will be a timelapse from mid-day to night (with night city lights in the end). The 3D datas of Cityengine will be exported to Softimage, and finaly composited in After Effect.

I've been playing with some of the scenes exemples downloadable on the site. I've been really impressed with the "Venice" example, and I wish to use similar technique for generating my city.
So far, the final city isn't decided yet, I'm still practicing (with trial version).

At the moment, I've been able to "reproduce" the process on the city of Bayonne (France).
This is wat I did :

I grabbed a large satellite texture of Bayonne with precise Latitude and Longitude using Microsoft VirtualEarth Satellite Downloader http://www.allallsoft.com/mvsd/

I applied the same longitude an latitude coodinates in OpenStreetMap and exported.

I imported everything in Cityengine, just as explained in the Venise tutorial.
I generated the Street and the Buildings using the Venice Street.cga rules.

Everything worked perfect. The only thing that is not correct is the texture that should be mixed with the streets and buildings textures.
I placed the texture manually "below" the city model, not really precise. But I don't know how to input the X and Z offset of the Texture in the rule.

I know that is not the decent way to do this. I don't know what is ArcMap. Do I have a possibility to properly place the texture with Latitude and Longitude ?
How do I input the correct scale and offset of the texture in the cga rule ?

Thank's a lot for any help, suggestion, advice :)
