    Hi guys,
    i'm trying to build a tracy with BTB, which world quite well, except that the track doesn't have a sky.
    Any idea how i can ad a sky?

    Check out other tracks and find texture "sky.tga". copy and paste to your track, and add a shader.

    I took sky.dof and sky.tga from carlswood and copied it to my track. Added some code to track.shd but nothing changed.
    Code:
    vf_sky
    {
      vertex_shader
      {
        ;file=sky_daynight_v.cg
        file=sky_v.cg
      }
      fragment_shader
      {
        ;file=sky_daynight_f.cg
        file=sky_f.cg
      }
    }
     
    shader_sky~vf_sky
    {
      sky=1
      cull=none
      layer0
      {
        map=sky_clouds.tga
        depthwrite=0
        depthfunc=always
      }
      layer1
      {
        map=sky_night.tga
        depthwrite=0
        depthfunc=always
      }

    It also needs to go in geometry.ini of course. Carlswood just has
    Code:
    sky01
    {
      file=sky.dof
      flags=0
    }
    There's a flag for having the skybox move around with the player, but for small tracks this is adequate.

    Awesome, thanks a lot. finally its usable.
    However, the sky is really bright. Can you tell me if I can change this? or is it just changing the sky.tga?
    thanks a lot for the help.

    when you're ingame, enter 'edit tod' which means Time Of Day, a relative new feature. From there, you can tweak each TOD point & get the brightness value as you intend.

    There's also sunny = 0 - 10 or clouds = 0 - 3, just choose a value from the range I've indicated.
    Last thing, the range of sky values was re-normalized to 0-1 range along with other variables, so keep an eye on it & compare older special.inis to newer ones, to get the big picture !

    Make sure you read racer.nl, it's full of info...

    Thanks for the help so far.
    After I add the sky on a computer with nvidia graphics (nvidia geforce 8600 gts) the track and all objects turn dark. The sky can be seen and when I turn on headlights i can see some objects.
    Don't have the problem on a friends computer with ati graphics (ATI Radeon 4800).
    Any suggestions on how to "turn on tthe light"?

    Sorry but I'm not very experienced with this.
    What exactly do I have to change?
