How to do fade out animation when changing screens

[JPabl.1]

Hi there TouchGFX team!

I need to do a fade out animation when changing from my welcome screen to my home screen, but I can only see 4 options on TouchGFX designer. 

I suppose I need to change the alpha value, but there's several widgets on each screen, so I'm not sure updating each one of those alpha values is the best approach. 

How can I implement it?

Thanks a lot in advance

Hello @JPabl.1 ,

A previous answer suggested to fade in a black box before switching to the new screen and on the new screen having a black box fading out.
