The model is done (needs only turrets)
After I looked at the pics from the links in this thread, I fianally had enough material for reference.
I noticed I did a lot of thing wrong and started a pain-staking job or repairing it...nedless to say, it was a b***, since the whole ship was a single object, so deleting the legs & part of the middle section without screwing the geometry was hard work. Had to re-load the scene 7 or 8 times!!
But I did new legs and sucesfuly unioned them, made a new central section, made the bridge and senros section, shortened the main gun and made a few custom textures...
So, without any further ado:
PCS exports it without any problems, but FRED doesn't want to save the mission with the SDF in it....
