This is just a basic implementation of the lighthouse: no underneath rock, no lantern, no collision, no water reflections, no shadows, etc.
At this stage I am mostly concerned about the placement of the beacon relative to the seabottom/sea level. If everything works well, we will keep on adding new features step by step.
I am sorry if this alpha release took longer than expected, but I couldn't get the texture to show up in s3d unless I embedded it. No idea why it happens, and after several cycles of trial and errors I decided to give up. I hope the texture will look okay in game (though we might decide to devrese it in size: now is 2048 square pixels, I bit too big for SHIII probably).
Let me know and fingers crossed
