Ok, I'm abit lost here.. I need to create a texture from an unsigned short [256*256] array. This is the same as a [256*256*2] byte array , I think.. I don't really understand how this works, since from what I can see only 2 pixel colors can be stored for the texture (wich is 256*256 pixels) I can export the texture to a 16bit TGA, and when opening in photoshop it has the correct RGB values and displays correct. when I export it I do: (after writing tga header)

      
fwrite((byte *)mMaterial[num]->mImage, sizeof(byte), 256*256*2, stream);

Where mMaterial[num]->mImage is a 256*256 unsigned short.
  

But this doesn't really have anything with my question to do, just some extra information It's when I try to create a texture from this data I get problems. I tried with:

  
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB16, 256,256,0, GL_RGB, GL_UNSIGNED_SHORT, mMaterial[num]->mImage);
      

But that creates a grayscale texture wich is tiled and combined with textures wich comes after the current in the source file. Here's a screenshot that might explain better And this is how the texture looks like after beeing exported to tga the way I said earlier, and this is what I would like to have in openGL aswell.

From your export code, it looks like you''re writing it in 16bit format to the file, correct? And, after you load it all (still 16bit format):

  glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB16, 256, 256,//                             ^Store as 16bit in Video Memory    0, GL_RGB, //     ^Read in in the format [R][G] (continued…)<br></font><br>    GL_UNSIGNED_SHORT, mMaterial[<font color="purple">num</font>]-&gt;mImage);<br><font color="gray">//  ^Of 16bits per part. So that''s 16R_16G_16B, 48bpp…<br></font><br>  </pre></font></td></tr></table></center><!–ENDSCRIPT–><br>That''s not what you want to do I assume.

Nevermind, solved it.. had to write a 16bpp->24bpp converter and then create the texture using normal GL_RGB,,,GL_RGB
Every other way failed, tried with GL_RGB5 and so on, bute nothing seemed to work.
