Have followed the tutorial in Sbuilder on how to create an island. Drew a polygon and used HYDRO_GENERIC_OCEAN_PERENNIAL as its type. Drew another poly inside the previous one and created a hole. Hole is created. Compiled the drawing. Moved the resulting CVX-OU812.bgl to my FSX/addon scenery/scenery folder. Started FSX, no island. I'm missing something, just don't know what. I have done this a few years ago with no problem. Guess old age is catching up. Any help is appreciated.
