Oh, and on the textures, I didn't have them on any model I imported either. I assumed that was because I only extracted the .pof from the VPs. I'll have to see if I can get the textures working as well...
That's most likely because of case sensitivity: PCS2 handles textures case-sensitive if the OS filesystem is case-sensitive (i.e. on Linux, but not on Windows). And only for unpacked textures IIRC, not for VP-packed textures.
FSO handles them case-insensitive on all systems, so this could be seen as a bug in PCS2 (which, I think, should reproduce FSO's behaviour in this matter). I reported it
here, but so far it hasn't been fixed, apparently.
