I think it has something to do if the texture is rotated or mirrored in the progress of texturing.
I have used such a way for texturing my model, because I want only one texture image, which is easy to change. Otherwise you have to change multiple images. If you have a complex model this becomes worse ...
Is there a way possible to reimport the kmz export in an other programm to create a single uv-texture from all these seperated ones ?
Hi Gaieus !
Thanks for welcome and reply !
I have attached a simple model as an example for testing.
Hi !
I have a problem with exporting my model. I have made a texture map for my model (only one material with all faces flatened). All the model faces have this material texture stretched to the right part.
Is ther a possiblity to export the model in a way to keep only one material texture ? I have only the free version of sketchup and tried the export to KMZ. But here the Texture is spitted in many sub textures ... 
many thanks for any help ...
