Problem

Cinemachine virtual cameras that previously had a direct scene reference to the player's Transform (Follow / LookAt) lose that reference when the player is instantiated at runtime (spawned), resulting in cameras that no longer track the player.

Root Cause

Scene-serialized object references to the player are null after spawning because the player GameObject no longer exists as a pre-placed scene object — it is instantiated dynamically.

Proposed Fix

Add a small CinemachineTargetBinder MonoBehaviour to each virtual camera that needs to track the player. On Start (or whenever the player is spawned/ready), the script:

Searches for the player instance (e.g. by tag "Player" or a singleton reference).
Assigns the found Transform to CinemachineVirtualCamera.Follow and/or LookAt.

// Example sketch
void Start()
{
    var player = GameObject.FindWithTag("Player");
    if (player == null) return;
    var vcam = GetComponent<CinemachineVirtualCamera>();
    vcam.Follow = player.transform;
    vcam.LookAt = player.transform;
}

If the player spawns asynchronously, the binder should listen to a spawn event/callback instead of relying on Start timing.

Acceptance Criteria

CinemachineTargetBinder script created and attached to all relevant virtual cameras.
Cameras correctly track the player after runtime spawn.
Works for both synchronous and asynchronous spawn flows.
No hard scene references to the player required on the camera GameObjects.

## Problem Cinemachine virtual cameras that previously had a direct scene reference to the player's `Transform` (Follow / LookAt) lose that reference when the player is instantiated at runtime (spawned), resulting in cameras that no longer track the player. ## Root Cause Scene-serialized object references to the player are `null` after spawning because the player GameObject no longer exists as a pre-placed scene object — it is instantiated dynamically. ## Proposed Fix Add a small `CinemachineTargetBinder` MonoBehaviour to each virtual camera that needs to track the player. On `Start` (or whenever the player is spawned/ready), the script: 1. Searches for the player instance (e.g. by tag `"Player"` or a singleton reference). 2. Assigns the found `Transform` to `CinemachineVirtualCamera.Follow` and/or `LookAt`. ```csharp // Example sketch void Start() { var player = GameObject.FindWithTag("Player"); if (player == null) return; var vcam = GetComponent<CinemachineVirtualCamera>(); vcam.Follow = player.transform; vcam.LookAt = player.transform; } ``` If the player spawns asynchronously, the binder should listen to a spawn event/callback instead of relying on `Start` timing. ## Acceptance Criteria - [ ] `CinemachineTargetBinder` script created and attached to all relevant virtual cameras. - [ ] Cameras correctly track the player after runtime spawn. - [ ] Works for both synchronous and asynchronous spawn flows. - [ ] No hard scene references to the player required on the camera GameObjects.
