UMG Animation start/end bug

Hi

I just discovered a bug within the UMG animation editor.

I am currently doing animations for my main menu widgets, I want the animation to go from 0.0 to 1.5, however the animation editor seems to be remembering keys that have been deleted previously, such as -0.1 and 3.5, and thus plays from -0.1 to 3.5 for some reason.

I was able to replicate the issue, here are instructions on how to replicate the problem:

  1. Create new widget blueprint
  2. Add button to canvas
  3. Create new animation
  4. Add button to animation
  5. Create a “Render Transform” track on the button animation.
  6. Create a key at 0.0 and a key at 1.5 (with or without x/y movement value)
  7. Play the animation (It plays from 0.0 - 1.5 as you would expect)
  8. Add a new key at 3.0
  9. Delete the new key at 3.0
  10. Play animation again (It now plays from 0.0 - 3.0…)

I think it would be great to be able to set a start and end point of the animation like one would do so in any sort of animation editor.

Also, it would be great to be able to change an element of an animation. For example if I have a button, with keys already laid out, but I actually want to change that button element to a Text element or something else.

(Also, I tried to add the tag “Widget Animation” but there is only a tag for “Widget aniamtion”… which may make it more difficult to find topics related to widget animation :wink: )

I hope this helps :slight_smile:

Hello Otreum,

I was able to reproduce this issue on our end. I have written up a report ( UE-22840) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.

Make it a great day

Thanks Rudy, glad I could help.

I hope you have a great day too! :slight_smile:

Just want to say that this bug still exists as of 4.14.2

It still exists :confused:

Please forgive my lack of real terms - long long day - if you are still running into this problem, you need to click on your tracks in the timeline where your keyframes are and you will notice a very hard-to-see bar with start and end points that will be stretching beyond your keyframes. It kind of looks like what you would expect to see in after effects - grab the ends and move them to the correct start and end points. if you need a better explanation leave a comment here and I’ll reply when my brain is working better.

If it’s what I think you’re asking… we solved it unticking "Keep Playback Range in Section Bounds

Hope this helped! :slight_smile:
