A recent addition to the 3D Unity tools is ProBuilder, which allows you to create and manipulate geometry inside the Unity Editor. Much more powerful than the existing Terrain editor, ProBuilder allows you to create 3D primitives and then manipulate them, such as by extruding or moving vertices, edges, or faces, and then painting with colors or texturing with materials.
In this recipe, we'll create some geometry that might be useful for an original game, or to add to a 3D Gamekit Scene.
If you've not used a 3D modeling package before (such as Blender, 3D Studio Max, or Maya), then it is well worth exploring the different features of ProBuilder. By doing so, you'll learn about some key concepts, including the following:
- Vertex: A point where lines touch – a corner where the edges touch
- Edges: A straight line between two vertices
- Faces: Flat 2D surfaces, usually a rectangle or triangle:
