This screenshot is from my single-player survival world that happened to spawn me on an island. The island is actually quite far away from other land masses, and made for a really fun world.
This is an earlier map of my world, prior to when I had expanded further south and added the lighthouse seen in the screenshot.
This has got me wondering, is there a mod that allows you to build lights that have a beam pattern? Like a lighthouse can project light a great distance but only in one direction.
