ok.. sorry i have been away and have not been able to give a little bit of advice..
even if you have a low poly saucer u can still chamfer the edges to make it smooth..
select edge - selection modifier rollout - ring (all outer edges selected) then chamfer..
you may need to tesselate by face afterward, to tidy up but it works...
also after selecting ur edges to create the phaser strips.. use the same method again...
ala... low poly saucer high poly phasers... and rim...
catch me on msn if ya need help..
PM me for me addy or ask starforce he has it
