Lights in games dont work

I’m not talking about games that I did, but any game that uses the unity engine.lights simply do not work.Neither flashlights or downlights. I tried with every game and the problem persists.If anyone can help, I appreciate it a lot. I want to clarify that I am not a programmer.And sorry for the bad English, Im from Argentina.

There are several possible answers, depending on what you mean by “lights don’t work” (Unity doesn’t have flashlights or downlights - it has point, spot, and directional lights):

  • If lights are not casting shadows, that could be because you’re using Unity Free rather than Unity Pro.
  • If you get plain diffuse textures rather than correctly lit objects, it could be because the shader used by that material doesn’t run on your graphics card.

Can you provide more details of your system (particularly your graphics card), and a screenshot of a game or project (e.g. one of the unity demo scenes) that you believe is incorrectly lit and it might be possible to help you more.
