How do I use the QML 3D Model type?

AI_Messiah

This is something that I really want to use, but how do I define the model itself. I mean how do I create an instance of the 3D Model. I tried to use this code that I copied

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick3D 1.15
import QtQuick3D.Materials 1.15
import QtQuick3D.Effects 1.15
import QtQuick3D.Helpers 1.15

Window {
  id: window
  visible: true
  width: 1280
  height: 720

  // Viewport for 3D content
  View3D {
    id: view

    anchors.fill: parent
    // Scene to view
    Node {
      id: scene

      Light {

        id: directionalLight

      }
      Camera {
              id: camera
              // It's important that your camera is not inside
              // your model so move it back along the z axis
              // The Camera is implicitly facing up the z axis,
              // so we should be looking towards (0, 0, 0)
              z: -600
            }

            Model {
              id: cubeModel
              // #Cube is one of the "built-in" primitive meshes
              // Other Options are:
              // #Cone, #Sphere, #Cylinder, #Rectangle
              source: "#Cube"

              // When using a Model, it is not enough to have a
              // mesh source (ie "#Cube")
              // You also need to define what material to shade
              // the mesh with. A Model can be built up of
              // multiple sub-meshes, so each mesh needs its own
              materials: [

                        DefaultMaterial {

                          // We are using the DefaultMaterial which
                          // dynamically generates a shader based on what
                          // properties are set. This means you don't
                          // need to write any shader code yourself.
                          // In this case we just want the cube to have
                          // a red diffuse color.
                          id: cubeMaterial
                          diffuseColor: "red"
                        }
                      ]
                    }
                  }
                }
              }

When I run it I get the error: QQmlApplicationEngine failed to load component
