ng. Is there anyway to get the CityGridXML textures be true in the facade like the CityGML origional file?

I try to tranform the cityGML to CityGrid XML. The CityGML have surface of roof, wall and texture - when I try to tranform to CityGrid XML - just a roof is ok about geometry and texture. But when I tranform a roof+wall of the building - the texture is wrong in almost building.
