Hi! I´ve got a problem with Jim´s lighting system. I can´t get any kind of light to work, only the ambient light.

  
  // in BOOL cApp::Init()

  m_Graphics.EnableLighting(TRUE);
  m_Spot.SetRange(1000.0f);
  m_Spot.SetType(D3DLIGHT_POINT);
  m_Spot.SetDiffuseColor(50,230,90);
  m_Spot.SetAttenuation0(1.0f);
  m_Spot.SetAmbientColor(55,50,0);
  m_Spot.Move(-631.281f, 10.0f, -330.671f);
  m_Graphics.SetLight(0,&m_Spot);
  m_Graphics.EnableLight(0,TRUE);

I´ve loaded a x-file and checked the normals in my 3d-program. They are all pointing outwards. What´s wrong? Michael

It looks like your ambient is dark green, and the spot light is slightly less green/red

Note that these colors would be heard to differentiate on a model, try bright colors like yellow, pink. Make sure that your light is on the same side as the camera, not behind the model, etc.

Make sure you''ve initialized the light, because I killed a lot of brain cells figuring that out

I don''t really know how that lighting system works, but usually the colours ranges from 0.0f-1.0f...
