300 heroes, 70% of the file parsed—need help.

I’ve lost count of how many attempts I’ve made, but I still haven't managed to fully restore the mesh. Is there anyone knowledgeable about this who could help with the .model/.x formats from the game *300 Heroes*? I don't want to proceed any further until I've restored the mesh; I was able to extract the model, bones, and animations from the files—they aren't encrypted, just using a different structure.

The problem: the rendered model has holes. I want to patch them, but nothing is working so far. When assembling the model at the vertex level, it looks perfect, but it tears apart when the triangles are assembled.
