you dont NEED to constrain yourself to such a low polycount, though i do indeed encourage you to try. Just please, for the love of f***, DONT TEXTURE THE FREAKING RIBS... it looks horrible even with a bump map (which BC doesnt support anyway)
But hey, if you want some BSG models to include, let me know.... i have two low-poly Valkyrie-Type battlestars, MK2 Viper, both Raptors, Pegasus and Galactica, amongst others. I think theyre all UV'd already too. Built by me and i think it was Limey who UV'd them... just lemme know in a PM.
