Good day.

I discovered CanvasGroup some weeks ago, and I think is very usefull, because all element inside the canvas will change its alpha only with 1 command. If in the future you change or add some element in the canvas, you do not need to change the code or create new variables to change its alpha, because CanvasGroup will apply automaticly the alpha value to all elements and all its childs, so....

I recommend to use CanvasGroup to modify alpha.

Bye!

Yeah I think this way too, but if you got a bunch of tiny bits of UI like Text or Image that should be faded separately, this may be the way to squeeze a little bit of performance
