Hi.
I would like to share one environment we made recently to use it as background on one other project. I have tried to cover all important points in this “tutorial”, but if you have some additional questions, I will be more then happy to replay

I have changed title of this topic so that I don’t start a new one, since it’s all part of same project;
Here is gallery with some screen shots of interior of old Roman military complex, for witch I have made above mentioned background:

And here is download for test build:

i have to say that this looks very realistic, keep up the good work!
hi.
Here is link to dropbox gallery with some updates regarding environment and terrain; and I have made “Info-markers” prototype, that will be used to display some information about specific area in complex:

And one more update… It’s getting close to finish; just one building left to prepare and import in to Unity, and 3d modeling stuff is finished.
