I added a menu to allow you to change the textures of the islands and beaches:
Use four corners (available as a package) to surround one island sim:
Combine them to surround any setup of connected sims, like this:
Some technical data: all elements are just 1 object. The corners are 34 prims, the straight elements are 23 prims, and the inner corner is 13 prims. They all have "drag and drop" technology installed, just drop them close to where you want them, and they will move into place!
Do you need a large number of them? Contact me and ask for a discount!
