TBH, they look odd in the Max 3 render, it's as if they are not set up correctly. One thing I did descover in my experiments is that in order for them to work properly, all the pieces which contain the animation on the mesh (in this case the outer bussard domes) must be attached to form a single object.
Edit: Here are the example bussards for Max 3 I did a while back. I've also made instructions for how to transfer them to your model. (For Max 3)
1-open the example max file provided
2-Open the material editor and select the material for the outer bussard dome (the one which uses the file bussards.ifl for the texture.
3-Click on the Put to Library icon (hover the mouse over the icons til you find it), give the texture a name then click Ok.
4-Open your model and select an unused material in the material editor.
5-Click on the button marked Standard and in the opened menu select Mtl Library from the Browse From section.
6-Select the matirial with the name which you chos in step 3 and click Ok.
7-Apply this texture to the outer bussard domes ensuring with mapping that they will spin in the appropriate direction and that the 2 domes are then joined together to form one object.
Hopefully this will then get the bussards to work, it has for me each time i've done it this way.
