ok, heres a short tutorial for u, that u could put on ur site, the basics:
1. use vpview to extract the textures and model from the vp file
2. convert the model (.pof) to .cob by using a convertor like pof2cob or segeltuch
3. get hold of a program called 3D Exploration (3dx).
4. in 3dx, u can convert all the textures from pcx to bmp format, so the model gets skinned automatically. out the models n textures in the same folder for this.
5. in 3dx, after uve positioned the model in the angle/direction u want it to be, click on file and "render to file". i usually set the background white first, and render the ship really big, so that it looks good when u make it 1/4th the size and use it in ur render.
6. load the render file u saved to in photoshop
7. copy it to a new psd, and use the magic wand tool to get rid of the background (just click on the white background once, and press delete).
8. now u can resize the ship for ur requirement, though i normally make the entire render at double or 4x size, and release the smaller version in the end.
9. build ur scene. cut out the jet flames of the models in photoshop, and replace em with lens flares. use axion flare effects plugin for this.
10. use plugins like flaming pear's lunarcell and solarcell to make planets n stars for the background. use glitterato for nebulae n stars.
11. remember me whenever u render
thats it i guess
