There are currently three types of worlds in 3dSunshine:

Minecraft Worlds: If you have Minecraft installed 3dSunshine will automatically fetch all of your Minecraft worlds. To load one select Minecraft worlds and then chose the map you'd like to build in.

Freebuild World: This is the section for you if you don't have Minecraft installed (or if you do and you want a place to mock up designs). Select one of the blank slates to build in, or check our one of our cool demo builds.

Tutorials: The first time you launch 3dSunshine you'll automatically enter the tutorial process, but if you want to show them to your friends just open them from the world menu.
