I'm intrigued, Don. But SFC1 models won't work for OP, as I understand it.
They can.. but you have to convert the textures to .BMP from .PCX (if they're still .PCX textures with the SFC 1 mesh). You just won't have illuminated areas like nacelles, torpedo tubes, etc.
But refitting a SFC 1 mesh for SFC 2/3 isn't that hard.. if people'd explore my site, or Mackie's.. they'll find a tutorial I did on how to convert a SFC 1 mesh to SFC 2. And from there, to 3 if you wanted it. The TOS Akula kitbash I did (as an example) started off as a SFC 2 mesh from Lord Schtupp, and once the kitbash was complete, from there went into both SFC 1 and SFC 3. I use it as my FDD on the SFC 1 Demo I have installed on my texturing machine.
