For italian people: come funziona?

1. Timeline>Update —> Set Brighness: esegue un update continuo di Set Brightness ad ogni fotogramma

2. Timeline>Brightness —> New Brighness: fornisce il valore variabile nel tempo Brightness

3. SetBrightness>Target —> Point Light 1: setta la luminosità di Point Light 1
