I'm at the point where I need to do some in-game testing to verify the new vessels will work properly. I've recreated from scratch the T, N and O files and tested them on existing SH4 meshes. Now I need to see if my UV mapping and meshes are going to work correctly. Making the individual components is one thing, having them work in harmony is another...
So, I'm cooling my heels a bit until we can get an SH4 .dat produced...
