How to create roof textures(ortho image) and wall textures in cityengine?

[chandrasekhar_reddyguda]

Hi,

I am new to city engine , 

I have around 5000 Polygons with elevation attribute information.I would like to create texture for all the buildings using City Engine.

Roof texture has to take from Ortho Image and walls are generic textures.

I able to create roof textures as shown in the following URL  http://www.geoplanit.co.uk/?p=470 , and along with this i need to add wall textures,I have tried few rules from ESRI help documents but not succeeded. 

kindly provide a Rule file to create textures both roof top and walls.

Regards,
