I've been using the Ogre exporter for Sketchup quite a lot. One
problem I run into frequently is with Sketchup models that have
surface textures defined as colors rather than as JPG files. When the
meshes are passed through all the conversion steps, one ends up with
a .material file like this:

In this model, only one material can be imported (the second one,
defined as a JPG file.) It would seem easy and logical for the the
tools to generate 16x16 JPGs for the pure colors and add add the
texture_unit tags so that they could be imported as textures. If this
were done, a great many more models would be immediately available for
use in realXtend.
P.S. I have modified the Ogre exporter to simplify the importing of
Sketchup models. See
