UEFN - Session One - Build your world
2a. Customise your island
This is your 3D world. The window with the green grid is the Viewport. You can decide how your 3D world will look.
Change the shape of your island
The floor of your island is made up of squares placed on a grid. You can delete large grid squares to change the shape of your island. Notice the reflection of clouds drifting by!
