UMG Timeline Update Bug

Development Programming & Scripting UI

Hello,

I am using UE 4.7.5 and having an update problem with UMG. I have created 2 animations (slide in and slide out) and both of them are triggered by right clicking. I realised a few minor issues on GUI just after creating animations. Problem is when I do any changes on any Widget, they all seem to be in the ofset of my first frame where my Border and subs are out of CanvasPanel, therefore it remains invisible.

My animations are .25 secs and I am in .50, where my Border is completely visible. It seems like updating within Designer panel doesn’t update the timeline frame.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. If so, can you reproduce this issue in the latest release of the engine (4.7.6)?

Sorry, my windows had issues again. Took a while to format and install everything from scratch.

As a late response to your comment above:

I was able to reproduce the issue in 4.7.6 in a blank project.
Here is step-by-step

  1. Created a blank project Minimal_Default
  2. Created a new WidgetBlueprint
  3. Inside Designer, I created a border within canvasPanel, snapping bottom with full width
  4. Created 2 animations to be used later from LevelBP: Sliding in and sliding out through Y Axis. Default position is out of canvas. I didn’t use any BP yet, now I am sure it is about UI problem.
  5. I added a button inside the border

The problem occurs here. Whenever I make a change (adding a new element, removing or moving etc) problem occurs.
Even if I was at the 2.25 right now where the border slides in and inside the canvas, it shows frame 0 state where it is out of the canvas. FYI, in timeline you can still see the position is in 2.25 acting like 0

When I click 2.25 again, it shows the proper position of border (FYI I removed the button to test if it is still problematic)

I have shared the designer tab, but since I didn’t do anything in graph didn’t need to send the screenshot for it.

If you need further information about the bug please let me know. At least my PC seems stable now. For more info I can record a video, or even skype

Thanks so much for your time

Hello Rudy,

Thanks for the update. To add more, the bug doesn’t seem to interfere with anything else. I have tried a few other animations and integrated them with BP’s. Only gets frustrating time to time :slight_smile: If I come up with a different problem with this issue, I will also reply here.

Best wishes!
