Objects

The video is a tutorial how to make objects, avatars can be a combination of objects that is why they come under the same name because they are both objects. When creating a object the user creates the shape, then adds any code or rules to the object, finishing with the rendering and release of the object into its 3d environment. However, this costs money and land is also charged. Objects are made of atoms and atoms are what build up this world.
