Unity scene fade in and out

[hy]

I am new to playMaker and still pretty new to unity too.
Can anyone give me guidance on how to do Unity scene fade in and out?
if there is some tutorial or sample i can look at, it will be great. If not, please give me a brief guidance. Thanks.

There is an action called "camera fade in", you could use this on start. It will allow you to choose a colour to fade from and set a time for it to take to complete.
