Quick answer: Weight is mass. Equalize for symmetric pivot, or weight focus target highest.

Boss arena with player + boss in TargetGroup. Boss weight 5, player weight 1. Camera centers near boss instead of midpoint. Weight skews center.

The Fix

CinemachineTargetGroup:
  Targets:
    Player    Weight: 1.0   Radius: 1.0
    Boss      Weight: 1.0   Radius: 3.0     // big radius for framing

vcam Composer:
  Group framing mode:    Group Group
  Adjustment Mode:       Zoom Only

Equalized weights pivot at midpoint. Larger Radius accounts for big targets. Composer auto-zooms to fit.

Verifying

Camera centered between two; both visible always. Boss never crops off edge.

“Equal weights. Radius for size.”
