I've been working with a model of the Enterprise, which is the nicest of the refit moviie models.  However, there is a bizarre problem with the texture on the saucer.  I have Vue6, and am using two maps, one for highlights, and one for reflection.  Mapping is set to Parametric for both, but the maps seem to move whenever I change a setting.  I have no idea how to fix this.  The original model came in from Blender, I believe--I've had the object file for a long time, and only recently started working with it again.
