This plugin allows to export the whole model or the selection to Collada file format while preserving/restoring the the texture's original file and the material's screen names.
This is useful since SketchUp's Collada exporter creates generic names which don't allow to identify materials anymore when you want to use the file in another software.
SketchUp also creates new textures images for each face with distorted texture coordinates; however these won't receive the original material's name.
If you need specific export options (from SketchUp's options dialog), feel free to edit the options_hash.
Unfortunately, SketchUp also creates generic material names ( %(#000000)[<auto>1]) when you import Collada files into SketchUp.
