TroubleshootingLoop Animation Stutter or Pause
Why looping animations hitch at the seam and how to check first/last keyframe continuity.
Roblox loop playback does not automatically invent in-between poses between the last and first keyframe. Align first/last poses (and root motion), then verify with a numeric loop check and viewport scrub.
Official animation docs note that looping does not automatically fill interpolation between the end and start of the clip. A mismatch at the seam causes hitching.
Expected: You treat first/last keyframe alignment as required for smooth loops.
For each relevant channel (root position/rotation, major joints), record first and last values. Use the Loop Timing Checker for numeric deltas.
Expected: Deltas are within your chosen tolerance — or intentional differences are documented.
Numeric continuity is not enough. Scrub across the loop boundary to catch interpolation or root-motion issues.
Expected: No visible jump at the seam in preview.
Some community posts describe pauses after mirroring or timeline slowdowns. Treat those as unverified for your exact plugin version until you reproduce them.
Expected: You reproduce on your version before calling it a known bug.
Last verified: Not yet version-verified — treat as general guidance.
