Well I'm miffed
According to granny viewer all my ducks are in a row regarding textures, vertices, texture coordinates, etc. for the King George gr2 file. But the hull still renders incorrectly. Now one thing I have noticed is that on some units where the hull is rendered incorrectly if I place the camera inside the hull (inside the ship) and look at the hull it's rendered correctly (with culling set to none). Puzzling
Another thing that maybe someone knows the answer to: how does one correctly render the other maps beside the diffuse map (self-illumination and bump)?
Some units have all 3 of these maps defined for a mesh and I'm currently only using the diffuse one.
