Motion tween on alpha isn't working
I'm trying to do the most basic thing: getting an element to fade in. Here are my steps:
1) Put the item on the stage (in this case, it's a bitmap image)
2) Convert it to a graphic symbol
3) Create a new keyframe on that layer
4) In the first keyframe, set alpha at 0.
5) Select both the 1st and 2nd keyframes and go Create Motion Tween.
The expectation is that between keyframes 1 and 2, I will see my element fade in. However, that doesn't happen. The element is at 0 alpha up until it hits keyframe 2, at which point alpha is 100.
It would appear that alpha and tweening do not work together. However, I've found documentation insisting it does, and the same thing was possible in Flash 20 years ago. So I believe it should work in Animate.
Any tips?
