Hello everyone,
I’m experiencing a weird issue on Unreal Engine 5.7 and I can’t find a solution.
Whenever I want a skeletal mesh or Metahuman to play an animation in a Sequencer, nothing happens in the Editor, except while simulating the Level…
Any animation like a basic Animation Track in a Sequencer or directly when adding an Animation Sequence in the Detail panel of a Skeletal Mesh, the character doesn’t move if the game is not simulating.
I made sure that Always Tick pose and refresh bones is enabled and no others parameters seem wrong. When I change some parameters in the Detail panel, the character animation kind of updates itself and take the shape it’s supposed to, but if I move in the Sequencer timeline the animation doesn’t play more.
It seems like UE doesn’t refresh any animation in the Editor if the Level is not simulating but I don’t know why.
Has anybody experienced the same issue and find a fix ?
Thank you 
A fix that comes to mind for me, is that you may have the “Realtime” viewport setting disabled. You can enable it with Ctrl+R, or with the three bars and picking the topmost setting under Viewport Options (Called “Realtime” with a stopwatch icon).
Tip: this applies to all kinds of viewports, including those found in the Niagara editor and Material editor.
Hope this helps!
Hi !
Thank you for your reply but unfortunately the animation still doesn’t play, even with Realtime enabled.
Here is a video that shows the issue :

I never had this problem before 5.7.0, it’s weird.
Did u got any solution for this problem. Am also facing this issue. It just ruined 1 day to find the problem. Unfortunately not able to find the solution.
Same sadly, I have no idea where it comes from.
On what version are you ?
I will try a previous to 5.7 to check because I never had that issue before.
Alright so I find a way to fix it.
I installed a most recent version (5.7.3) but at first when I opened my project I still had the issue…
So I created a new fresh one and quickly tested an animation, and it worked !
Try to install a new Engine version, create a new project and migrate your assets from your current project to the new one.
I hope it’s gonna work for you as well

I’m really glad it worked for you. Unfortunately, I tried that method as well, and it’s still not working on my end.
