Ok, I went in and cut the poly count down by roughly 600 polys. The only places left to cut down the poly count in large numbers are the impulse engines and the saucer itself, and those I will not touch at all for anything.
Question though, should I keep the phaser block placements and have phasers textured on, discard the blocks and put in turrets in their place, or turrets and blocks. And if I do go with turrets, should I try and go with something different, or just the regular sphere shape.
