Why does my Cinemachine Confiner 2D jitter at the bounds?

The follow target moves freely; the camera clamps each frame. The clamp+follow interaction can produce micro-oscillation. Set Slowing Distance > 0 so the camera decelerates as it approaches the boundary, eliminating the bounce.

What is Slowing Distance?

On Cinemachine Confiner 2D, Slowing Distance defines the buffer zone inside the bounding polygon where the camera decelerates instead of clamping. 0.5-2 units typical for top-down 2D.

Should the bounding shape be a single polygon?

Yes, ideally. Use a CompositeCollider2D set to Geometry Type = Polygons to merge multiple BoxColliders. Confiner 2D handles concave shapes but a single, simplified polygon performs better and looks smoother.

Fix: Unity Cinemachine Confiner 2D Clamp Jitter

Quick answer: Set Cinemachine Confiner 2D Slowing Distance to ~1 unit. Use a CompositeCollider2D for the bounding shape so the polygon is smooth. Camera now decelerates approaching bounds instead of bouncing.

Player walks toward the right edge of a 2D level. The camera tracks them, hits the confiner edge, and starts micro-oscillating because the follow component pulls right while the confiner pushes left.

The Symptom

Camera trembles when the player is near the level boundary. Smooth elsewhere. Worse with high follow damping.

The Fix

CinemachineCamera (vcam):
  Confiner 2D:
    Bounding Shape:    LevelBounds (CompositeCollider2D)
    Damping:           0.5
    Slowing Distance:  1.5     // THIS

Slowing Distance creates a buffer where the camera lerps toward the boundary instead of being instantly clamped. The combined motion of follow + confiner becomes smooth.

Bounding Shape

Build the level bounds as a single CompositeCollider2D:

Empty GameObject with Rigidbody2D (Static) + CompositeCollider2D.
Children: BoxCollider2D pieces with Used By Composite = true.
Composite Geometry Type = Polygons.

The composite produces one cleaned-up polygon. Confiner 2D handles it efficiently.

Damping Interaction

If your Follow damping is high (camera lazily catches up), reduce Confiner Damping to ~0.5 so the confiner doesn’t fight back. Tune both together.

Verifying

Walk the player to a corner. Camera should ease into the corner, not jitter. With Slowing Distance 0, you may still see jitter; raise it.

“Slowing Distance buffers the clamp. Composite for clean bounds. Camera glides.”
