Sidewalks graphic trouble : Texture and mesh ?

[aboudayinaAboudayina]

@First of all I should mention that I am newbie on this forum, so sorry if this was already discussed in another post.

(I work on CityEngine 2014.0 version):

> I noticed this 2 problems for me (visible in the viewport and still when you export the geometry):

1. the sidewalks sides UV textures are like Non-unfold and it may be a problem when your have a very big city!>
2. Why does the sidewalks geometry has all this useless faces  (it is visible in the " Inspect Model view" and when you export the geometry to) even between two sections of sidewalk there's useless faces.
   

Is there a way to overcome this? (for example creating his own sidewalk model) ?

Thx

best regards
