A quick update.
Privateer’s Hold now shows up pretty much correctly. All the pieces fit together properly, including doors and decorations. It includes all 5 dungeon tiles (RDB files). Next up is to fix up texture coordinates on faces with more then 4 vertices and figure out why some of the textures seem to be using the incorrect index (although most are correct). Once that is done I can get simple collision detection and start getting flats and lights working.
Here are a few screenshots of Privateer’s Hold:
