Gameplay & UI Beauty & Texture Updates Pawns - Hair, Guns & Gear
Initial Start / spawn in here if interested. The easy way to play an Island is just to use the 'Biomes: Island' mod, but I personally disliked some sweeping changes they made to water and weather effects.
Instead, I used Map Designer - they have an option toggle to generate a 'Perfectly Round Island', regardless of map tile selected. I also used Better Map Sizes when selecting my tile on world spawn to reduce the size to about 90x90.
Finally with the map being so small I used Change Map Edge Limit to remove the restrictions on building at the map edge.
