Level Sequencer Misalignment: Sequence Plays in Wrong Level Environment (UE 5.5)

Hi everyone,

I’m facing a sequencing issue in Unreal Engine 5.5 for my shortfilm and would really appreciate any guidance or suggestions. Here’s a detailed breakdown of what’s happening:


  1. I have two separate environments:

    • A mountain level for a fight scene.
    • A river level for a swimming scene.
  2. Each environment is saved as an individual level in my Unreal project:

    • Mountain_Set
    • River_Set
  3. I created two Level Sequences:

    • Fight_Mountain → for a fight between characters on a mountaintop.
    • Swim_River → for a character swimming in a river.
  4. For each sequence:

    • I opened the correct level first, added my characters manually.
    • Positioned them properly within the landscape.
    • Then animated their movements with the level sequence tied to the visible environment.
    • Saved the level and the associated sequence.
  5. Everything looked correct in my previews.

  6. Problem happened when I shared the files with a friend for rendering.

  7. My friend opened the Mountain_Set level and then opened the Swim_River sequence.

  8. Unreal rendered the swimming animation inside the mountain set instead of the river.

  9. Visually, it looked absurd—the character was swimming through rocky terrain.

  10. The issue here is that Level Sequences don’t enforce which level they are authored in.

  11. Opening them without first loading the intended environment causes incorrect binding and rendering.

  12. I want to make sure this mismatch doesn’t happen again—especially when collaborating or rendering remotely.


What I’m Looking For:

  1. A way to ensure that each sequence loads ONLY with its intended level.(Also I don’t want to add non animated set elements in sequencer.)

  2. Or some binding method that can lock sequences to their original environment/set.


What I Need Help With:

  1. Is there any method to enforce level-sequence pairing automatically?

  2. Can a sequence be configured to auto-load its authored environment?
