    lighting from a skydome?

    I have created a terrain from importing a height map, and loaded a skydome around it, but outside of placing point lights everywhere, I cant find out how to mimic real sun type of light , and not a direct light over top by something thats maybe like 4pm mid day with shadows..

    thoughts?

    You'll need the skylight and directional light actors, found in the actor class browser. A skylight is basically ambient light that will illuminate every inch of your map, while a directional light beams light infinitely in the direction you point it in and casts shadows. The combination of a very dim skylight and a brighter sun-coloured directional light (or several even, as in the offcial maps) should give you the effect you're looking for.

      Setheran is right on this. It's pretty much the same approach in any engine or 3d Application. A Directional light shines a light from a defined angle onto the scene (it's physical positioning is often ignored as it's result is to imitate a sun a great distance away) and a ambient light to simulate global illumination (as light tends to bounce off other surfaces and relieve the harsh contrast of the directional light's shadows.)

      But Light cannot be directly cast from the skydome (Image based lighting)
