Well simply before you add the Scene to your ContentBranch of your Locale
traverse through the Graph. You will hit at the end a Shape3D because it's
a leaf and it doesn't have anymore children. When you reach a Shape you
can return it's geometry by getGeometry(). You can either check what type
of geometry it is by instanceof or by getClass().getName().

Yeah that's right when you run in compiled-retained or retained mode yes.

Well you can add texture coordinates before you add the scene returned by
the loader to your locale node. The only hard part is to find a
corresponding mapping, which looks good as you can't really tell from the
coordinates what primitive it might have been. So you're limited to
spherical, cylindrical, cube-mapping, etc.

Maybe it couldn't find the texture-files or there is no image-loader for
the sort of file you used as texture?
