Why is my unreal engine 5.6 curve editor only showing points and no lines

Hi everyone, I am trying to work in the Sequencer curve editor in Unreal Engine 5.6 and I only see the points for my keyframes. There is no line connecting them like I am used to seeing in UE 5.4 ( here is how it should look). It is just floating points on the graph and it is making it really hard to adjust the animation. I tried selecting them and playing with interpolation settings but nothing seems to bring the lines back. I even tried changing to Auto and Linear but it still just shows points. Am I missing some hidden setting for this?

Hi,

We are not aware of any issues in this regard in 5.6. There were performance improvements for painting these curves wich you can disable with console variable:

CurveEditor.UseCurveCachePool 0

I hope this workaround helps to overcome the issue for you for the time being.

For further investigations, can you share with us your:

  • Operating system
  • Basic PC specs
  • A short video in how to recreate the issue

Also if there is anything special about the cube you’re trying to animate, or any plugins or source code modifications in place, let us know.

We’re happy to investigate the actual issue with these infos!

Best wishes

@Flo.Schar1 ,
Thanks for your help. I tried using the console variable you mentioned, but unfortunately it didn’t fix the problem.

Here are my details:
Operating System: Windows 11 Home 64-bit
Processor: AMD Ryzen 7 5800H with Radeon Graphics
Memory: 32 GB RAM
Graphics: NVIDIA GeForce RTX 3070 Laptop GPU (8 GB VRAM)
DirectX Version: DirectX 12

Here’s a short video where I reproduce the problem
The issue isn’t specific to the cube, that’s just a simple example to demonstrate (no special settings or modifications applied) . Basically, no matter what keyframes I add in the Sequencer curve editor, I only see the points , there are no connecting lines like in previous Unreal versions.

For example, in the video I animate the Z-axis rotation, placing one keyframe at timecode 00:00 and another at 6:00 (six seconds). Normally, in the curve editor, I expect to see both the points and the connecting curve , a straight line if linear, or a smooth arc if cubic. Instead, I only see the floating points with no visible curve between them.

Hopefully this gives enough context to help investigate.
