Check in your "mesh" file that you have converted, that the textures have been written in on conversion. Tech antimodule for eg.

Material
        DiffuseTextureFileName "FrigateTechAntiModule-cl.dds"
        SelfIlluminationTextureFileName "FrigateTechAntiModule-da.dds"
        NormalTextureFileName "FrigateTechAntiModule-nm.dds"

sometimes they are missed for some reason and you end up with this;

Material
        DiffuseTextureFileName ""
        SelfIlluminationTextureFileName ""
        NormalTextureFileName ""

You can just type them in and save.

Also make sure you have put the texture files in the texture folder of your mod.

Haven't run into that 1 before. At a guess, perhaps you have a polygon with 5 sides or more.

Hmmmmmmmm thanks a bunch guys. Superzero, I checked the file but it did get the textures written in. I DID forget to put the textures into the texture folder but it still shows as black in-game. Model contained no exotic polygons.  Myfist, I probably did forget to freeze it and am making a new test model to see if that makes a difference.  Thanks guys

What size is the texture set at on your .dds? As I've experienced the same when the textures aren't set at 1024, 2048, etc

That's a good tip, I'll try it. Thanks. 

Texture size wasn't it . 

Ok, so I ran the game in Dev mode (don't ask why I just now thought to try) and I get this:

Can't extract image info from file.......nm.dds

Which tells me that the problem is the normal file, which begs the question of what the proper protocol is for saving things with the Nvidia plug in. I mean it gives you so many options...

Thank you thank you thank you thank you guys!! My model is showing up in-game now . The only problem I have now is that my capital ship is tiny (radius 50) but im sure I can figure that out on my own. Here's a list of all that I did wrong for someone else's benefit:

1) I did not copy my textures into the mod's texture folder

2) I saved my normal file with the "normal" option in the Nvidia plug in instead of DXT5 ARGB 8 bpp interpolated alpha

3) I did not freeze my model before exporting

Well, thanks a lot guys for the help . How do I add to karma in this forum?

Hey Sup, is there a link to that whole  video series? It's unlisted on youtube. 

I did try to download this two times actually last week, I kept getting a 'file corrupt' error each time. Will try again, thanks. )

I am having a problem with this too. 3 our of my 5 ships are appearing black in the game.  I used gimp to make their normal maps and when I run the game in dev mode I get a texture mismatch error with their textures.  Cant figure out what it is..
