Moving an island is mostly checking that the furniture survived.
I've been carrying the saved world into Unreal. Pequeño Peligro reopened with its streets, buildings and placement intact, which was a relief. It also exposed the bits that didn't arrive looking right: materials, water, lighting and some character imports still need work. An island full of objects is a good start. It isn't a game you can play through.
At the same time I tried giving Correos Central some proper levels. The town centre now has terraces, stairs, roads and room for the market instead of a collection of buildings floating around a flat square. The picture above is from that separate Unreal layout study. You can see where I've solved a route and where the ground is still embarrassingly bare.
Next I need to fit the town into the island and find out whether Rusty and Bonita can actually get around it. Looking convincing from above is much easier than delivering a parcel there.
