@lee-g - You have added a Transition Progression Envelope and then not adjusted that Envelope. Do you want to Control the Progression of the Envelope, for Reversing,, or just do what @fr0sty has suggested?

Given the language barrier, this is going to be tough. 🤨

Maybe just a misunderstanding of how Transition Progress works. The keyframes of Transition Progress define "no transition" if the keyframe is at a zero position (on the ground of the Event) and they define "full transition" if the keyframe is at top position. So its curve acts vice versa to the regular Event's transition curve.
In other words: The keyframes and curve of Transition Progress control the transparency whereas the curve of the regular transition signals the opacity.

Not a bug but quite confusing from a certain point of view.

전환 진행 방식에 대한 오해 일 수도 있습니다. 전환 진행률의 키 프레임은 키의 위치를 ​​변경합니다. 일반적으로 전환되는 일반적인 이벤트입니다.
다시 말해, 전환 진행의 키 프레임과 전환은 전환됩니다.

그래도 좋지 않다.

 

나는 마르코의 댓글을 읽었습니다.
댓글 감사합니다.

나는 이미 이 사실을 알고 있습니다

그런데 이상하다고 생각하지 않습니까?
다른 그래프처럼(Start Transitions and Middle Transitions) 0%로 시작해서 100%로 끝낼 수 있지만, 끝 방향은 역방향입니다.

끝도 0% 시작으로해서 100%로 끝나야 합니다.

trans...

I read Marco's article.
Thank you for the comments.

I already know this fact.

But don't you think it's weird?
Like other graphs(Start Transitions and Middle Transitions), start with 0% and end with 100%, but the end direction is reverse.

The end should start at 0% and end at 100%.

Yes, I agree. It's counter-intuitive. I would expect the graph of Transition Progress would work same way as the graph of regular transitions.
