Issue when transitioning between screens via scale

I've been following the new manual How To "Creating Screen Transitions" and ran into a problem, when I wanted to change the property that's being transitioned.

Here's what the tutorial says in short: Create a single-keyframe animation for the start position and another single-keyframe animation for the end position. Use the Animator transition to blend between the two states. This works fine when I go from Alpha 0 to Alpha 1 or when I use the Rect Transform Anchors from one position to another. The Animator transition interpolates nicely between the values.

However, when I try to do the same thing with the Rect Transform Size of my screen element, there is no interpolation. It just jumps from 0 to 1. Why doesn't the Animator transition blend between the size as it does with alpha?

(As an alternative I can create two complete animations with two keyframes each, which make the size interpolation possible, but it just seems like a nicer solution to only have to define two states and then use the Animator transition to handle the actual timing.)

Thank you!

 

I had to experience the same issue.
I don't know why it doesn't blend like expected, but for me it worked when I replaced the 0 scale by a very small value.
For example in the first single-keyframe animation the Rect Transform.Scale would have a value of 0.001 and in the second one it would be 1.

Hope I could help at least a little!

 

Thank you for the reply! Setting one of the keyframe animations to 0.001 scale worked. I had the correct interpolation via Animator transition.

So is this a bug or maybe a missing feature, to tell the user, that he can't put in a zero scale? I know that zero scale doesn't actually make sense, so maybe it's a math problem, but then at least unity shouldn't let me put in numbers that cause problems.

 

Please file a bug report with repro steps and repro project. Thanks!

 

I built a nice testing project and submitted it.
