Use Facial Detection to detect faces of people using this effect. To detect more than one face, assign a Face Detection node to each face in the scene. It can detect up to five faces. Facial Detection is in the Head and face category.
|Which Face||String||The face to apply the effect to. Face 0 represents the first face appearing in the scene, Face 4 represents the fifth face appearing in the scene.|
|Begin||Exec||Execute the next node when the face is detected|
|Stay||Exec||Keep executing the next node when the face stays in the scene|
|End||Exec||Execute the next node when the face disappeared|
|None||Exec||Keep executing the next node when the certain face is not detected|
|Face Count||Number||The number of faces in the scene, the max is 5|
In this example, we trigger the appearance of a cube when we detect one face, and trigger the appearance of both the cube and the sphere when we detect two faces in the view.
