Unreal crashes when working with animations and UMG

Hello Unreal forum users,

I just want to complaint about Unreal Engine itself, because when I work with the animation sequencer or with UMG, Unreal crashes everytime I work.

This happens when I compile or save the project. I didn’t change the C++ code of Unreal Engine, so I don’t know what the real problem is.

The computer contains the recommended specifications for Unreal Engine.

I hope you can solve my problem, so I can work with Unreal Engine WITHOUT crashes.

Hello Skittluier,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. What version of the engine are you using?
  2. Can you reproduce this issue in a clean project?
  3. If so, could you provide a detailed set of steps to reproduce this issue on our end?
  4. Could you provide a screen shots to any blueprints that may be relevant?

Hello Rudy,

I’ll work on it right now. You’ll hear from me later!

Okay. I’ve done it.

  1. Version 4.7.6
  2. Yes, I can reproduce it.
  3. Used the template ‘First Person’ with C++ → Map ‘Animations’ → Created animation sequence called ‘Wave’ → Added some animation keys → Applied it → Saved it → Crash screen!
  4. There are no relevant blueprint there were made.

Can I get a cookie now?

Hello Rudy,

1 → The first thing I did was creating a new animation sequence file in the ‘Animation’ folder.

At your step 5 I used the First Person template skeleton instead of a usual image and moved the arms. Then compiled and saved.

2 → I can’t provide the dxdiag, because the PC is in the office, so I can check it on Friday.

3 → Not tried. I will try it on my home PC.

Here is a picture before the crash:

PS: I think the UMG crash was something rare, but the animation sequence is a frequent event.

Hello Skittluier,

I could not reproduce this issue on our end with the information that was provided. I have added an image to UMG and I have added several key frames but I cannot get the editor to crash.

Here are the steps that I took:

  1. Created a clean first person (C++) project
  2. Created a new widget blueprint
  3. Added an image to the designer tab
  4. Created a new animation sequence
  5. I set a key frames to move the image from side to side and up and down
  6. Compiled and then Saved
  7. No crash

Quick Questions:

  1. Are there any steps that may have been left out or that you may have done differently?
  2. Could you provide your dxdiag?
  3. Does this happen on all new projects that you create?

Hello Skittluier,

After realizing you talking not talking about animations in UMG I was able to reproduce this issue on our end. I have written up a report ( UE-15561) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information at it becomes available.

Make it a great day
