1. Where did you hear of it? We're always interested in learning where the steady stream of newbies is coming from
2. If you just want to see the HTL lucifer in action you can just download the 3.6.8 Beta VP files to get it (You'll also need the latest CVS build from the SCP's Recent Builds forum)
3. Nonetheless if you're interested in developing or bugtesting for FS2_open or just simply always want to have the latest stuff before it hits the media VP files you'll need to know so here goes.
For a new ship model to work in FS2 (or FS2_Open) it needs three things.
a) It needs the model. These come in the format filename.pof. These go in Freespace2\Data\Models if you've simply stuck the media.vp files in your main Freespace 2 folder.
b) You need the ship to exist on the ships table. For the lucifer this is already true. Just add the other components and it will work. If however you were adding a completely new ship to the game to use in a mission you were making you'd need to add the ship to the table. In the old days this was done by grabbing the Ships.tbl file and editing it but recently it's become possible to simply add a modular table extention file. This is a file which ends filename-ship.tbm and this goes in the data\tables folder.
c) Lastly you need the textures. If you are downloading a texture upgrade you may only have textures. Again these can already be present in the media.vp files so don't be surprised if you only get a pof in a download. Textures come in a variety of formats but will end in .eff, .ani, .pcx, .tga, .dds or .jpg. They all go in data\maps.
Not make sure you have actually downloaded a ship. Effects may have similar filenames but shouldn't go in the maps folder.
Anyway that's probably far more info than you needed so I'll just sum it up for you. You've only got the texture so far. You don't actually have the lucifer itself. Either get the VPs I suggested or go back to where you got the .dds file and find the .pof file.
