ehm, I'll try again...:p
first go to modeler and select all your polygons that make up the orange bussard.
( you can do this easily by first setting modeler in polygon modus and then going to the polygon statistics panel which you should find at the bottom of your screen ( I'm using 8.0 so I'm not completely sure about the exact location )
In this panel go to surface and select the surface that makes up your orange polygons ( called orange or bussard or something similar ), click '+' at the left and then you have all your poly's selected.
ok, next step : cut the poly's, go to another layer and paste them again, then select the poly's of just one of the bussards by dragging a circle around them with your mouse, cut them and paste them in another layer.
so you now have 3 layers : ship, left bussard, right bussard.
save and go to lightwave. load your model, select one of the bussards, and then click 'motion options' ( I believe it's at the bottom panel ) select a parent item for the object, which is your ship. Do the same for the second bussard.
select one of the bussards and then click 'move pivot point' ( I think it's in the modify tab ). drag the pivot point which will be in the middle of the ship to the dead center of the bussard. Save, and then do the same for the second bussard.
To illustrate what this does : try to rotate the bussard before moving the pivot, and then try again after moving it, you'll see that the center of rotation is changed.
Now this is done, you can set keyframes for the rotation of the bussards. When you move the ship around, the bussards will follow these movements, while their own rotation is still perfect.
in the pic the bussards are just orange, so their rotation will not be visible if you render, unless you set a texture on it.
This could be anithing from bump to dirt to whatever really....
hope this helps...
