Add 'Tween' behavior to that object.
Use two Tween actions:
Tween: Opacity, End value: 0, time: 1 sec, loop ON
Tween: Scale, End Value: 1.4, time: 1 sec, loop ON
Hello, i cannot find the "Opacity" and "Scale".
I have created "On start of layout" and added the "Tween behaviour" like you said but i cant find the "Opacity" and "Scale".
