I thought I'd get an Email when I receive a pm. Sorry, I'll check immediately.
The GTVD Aurora is a Terran-Vasudan hybrid (check the first post), and the aux. engines are arranged like the Hecate's main engines, plus the general design is a bit similar. Polycount is 18000, but with 40 turrets that are 170 polygons each. This is like 3 HTL Deimos's, so it's not that much, but I can decrease it to 8000 without loosing much detail. (with lowpoly beam turrets and less curves)
I believe the 18000 poly version could be kept for high-end computers (a Pentium 5 10GHz and three GF 7900's with 4GB ram and 1,5 GB video memory:)) in a different vp file with all the hipoly/hieffect stuff.
