Two ways.
Open the model in the Taldren Model Viewer (NOT the attribute editor, the Taldren Model Viewer is a seperate program, check the software page on taldren.com if you don't have it), rotate the models to the way you want them, and press Print Screen. Open up Microsoft Paint (i know...ick) and hold Ctrl and press V. Thats the same as going Edit -> Paste. The screenshot will appear there, highlight the ship in the picture, and do Copy, go to Photoshop and load up a blank copy of VL, TI, and BS, and paste the ship over it. Then select the Fill tool and in the pop down menu on the top select clear. Then click on the Blue part around the ship, it'll become transparent, and you'll just have the ship and the background.
Method two:
Using the blank VL TI and BS as the background (environment map), render the ship in the correct position and sizes.
Both of these require a blank VL and TI and BS- i got them from Chris Jones' SFC3 conversion tutorial, but i don't know where i got it...
