Here i try make small tutor about as to construct good meshes. Basic tutor say what we can use in pes stadium only simple meshes, and if man is not familiar with 3d building, he based only on the old tutors, which does not mention about the optimum method of the building of stadiums.
The simple example.
Both objects have the identical textures.

Created by surface

Created by simple meshes.

-----------------------

We can use 100% this 2 surface method, maybe another too i dont test.

Create surface (1), and appoint texture, just as with meshes.
Now we must Split(3) surface with polyline (2).
Press split button, select (1), press enter, select (2), press enter. ready.
Here result.

Now we have surface with good texture.
Last what we must convert surface to mesh.

Final element (5) we can import to pes

This method work good if you want creat "3d" seats. It is necessary to create a number of seats, with a maximum quantity, and to cut them.
p.s. thanks knell/igor that say me about split mode.
