@Visigoth: you're using too many polies for the chain rings. I would make all the links hexagonal with four sides on each division ((6*4 + 6*4 + 4*4)*2 = 128 tris for the chain instead of (6*2 + 4*6 + 6*6)*2 = 144 tris). It should look better an you get some polies for the other things. Usually going highpoly to lowpoly is…
No, what I mean is, didnt they already account for all the passengers with the corpses? If 300 people were found dead, and then 6 of them were all of a sudden alive, we have 6 bodies that are obviously not belonging to these 6 survivors.
