Prefab says “missing script”
A MonoBehaviour reference cannot be resolved. Restore the script/package or deliberately remove only the obsolete component.
Fix missing scripts →Unity prefab troubleshooting
Unity “missing prefab” problem? First identify what is actually missing.
The phrase “missing prefab” can mean a missing script, missing material, broken prefab reference or an object that exists but no longer behaves correctly. Use the symptom below instead of deleting components blindly.
Prefab renders pink / empty
Check renderer material slots, nested prefabs, variants and moved asset references.
Check missing materials →Prefab collides incorrectly
Separate collider geometry, Rigidbody, layer and trigger problems before changing code.
Collider troubleshooter →Not sure what broke
Run one non-destructive pass for missing scripts/materials, import settings, texture size and collider presence.
