This should be easy but it proved very challenging. I finally discovered that Collada is the best format to exchange objects, as long as I use the right export settings in Blender. Apparently on Vue XTreme supports fbx, so that’s out.
Anyway, this is four planes, each 1m square. Texturing was done in Blender and exported satisfactorily. Not sure if that will be the case with normal maps though, so will have to give that a try. Now to move on to something more complex.
