I’m currently modeling real city to use with Unity Flash-player. I’m modeling the city with Luxology Modo. Buildings dont give me headache, it’s the roads between buildings.
Idea in the “game” would be able to walk around thew city Google Streetview -style and that is why roads are quite important.
Problems lies in texturing those roads. As far I have made parts of road as mesh, then UV-mapped it and tried to make it fot along all other parts of road. If I use too large parts I will get huge UV-maps and huge texture sizes, if I make lets say 40*40 meter roads blocks I will have huge job to make these parts fit.
If there is some easy way to texture road parts so that I dont get huge image resolutions? OR make simple plane and “paint” roads and sidewalks in Unity to match real world roads.
For curved roads I use a long stripe of a plane which is basicly tiled in 2 pieces in width. Then I use this areas and move them on the UV map on an atlas texture and also do a lightmap UU if needed.
Then I use my programms bend modifers to get the curve shape.
City streets with 90 degree curves have the same workflow just without bending. Just make sure you tile textures.
If you use 512² for one piece of street, then you can have 16 variations on a 2048² texture for instance. Using 256² would result in 64! Then you can even use a 2nd Texture and so on.
Just avoid straight lines in curves to prevent distortions as the crossway shows.
