Why does Cinemachine still leave the bounds?

You're using the legacy CinemachineConfiner. Switch to CinemachineConfiner2D and click Invalidate Bounding Shape Cache. The new extension precomputes a confining polygon that respects camera ortho size.

How softly the camera approaches the edge. Set Damping to 0 for hard clamp; non-zero overshoots into the bound area before settling.

Bounding shape cache stale?

After resizing the PolygonCollider2D bound, click Invalidate Bounding Shape Cache on the extension. The cache holds a precomputed inner-polygon offset by camera half-size.

Fix: Cinemachine Confiner2D Clips Outside Bounds

Quick answer: Add CinemachineConfiner2D (not the legacy CinemachineConfiner). Bounding Shape: PolygonCollider2D covering allowed area. Damping = 0. Click Invalidate Bounding Shape Cache after edits.

2D camera leaves the world bounds at the corners. The legacy Confiner doesn’t account for camera size; Confiner2D does.

The Symptom

Camera shows void/skybox at room corners or after PolygonCollider2D edits.

The Fix

Vcam → Add Extension → CinemachineConfiner2D
  Bounding Shape 2D:    PolygonCollider2D (room outline)
  Damping:              0
  Slowing Distance:     0
  → Invalidate Bounding Shape Cache   // click after collider edits

Confiner2D shrinks the bounding polygon by camera half-size, then clamps the camera point inside that shrunk poly. Damping smooths approach but allows brief overshoot.

Verifying

Pan camera to corner. Camera stops cleanly at the edge with no void visible. Resize collider, invalidate cache, resize-clamps update.

“Confiner2D. Damping zero. Cache invalidated. Camera stays in.”
