Kendras experimented with the sector lights, so I cannot enter in the details. I think he tried blocking the light by using some barriers (though I don't think they were invisible: how can an invisible object block the light? :hmm2:), but the result wasn't satisfactory.

I had another approach in mind though: my (untested) idea was creating a 3D world-aligned particle shaped as a narrow light cone. In theory we should see a dim light beam when looking at the light from the "dark" angles, and a glaring halo when looking at it from the "illuminated" angles. At least this is how I imagine leading lights; sector lights with colored sectors may look different than I described above.

Leading light are often realized as two lights behind, so if you have both lights in one point and change course to the light, you know, that you ride in right course . Just imagine line and two lights <>------------------*--------* ( "<>" - your ship, "*" light)

True, but similar to range lights (which they are often associated with), their light is commonly only visible from certain angles. As an example of that, here is a chart showing the Düne (Helgoland) leading lights:

I understand, but there is so much lights and it is just Helgoland! I count for Helgoland with only one lighthouse.

I don't get your point here. You can give Helgoland any number of lighthouses you like, even zero. I was just making an example of a leading light coupled with a range light; a configuration found not only in Helgoland...

Well, i had on mind number of all lighthouses in the game.

Is it compatible with sh4? I mean model of lighthouse?
