sketchUp export problem

[Jakub Sulej]

Hi! I was making one big object in google sketchUp and I wanted to export it as kmz. file.
Problem is that I was using only 3 textures saved as png. and on every single part of the object I changed direction of texture.
When I exported I got 52 images in folder and every one has different direction.

How to export it by using only 3 textures?

Please help
