cinemachine-add-extension	Add a `CinemachineExtension`-derived component (e.g. `CinemachineDeoccluder`, `CinemachineConfiner3D`, `CinemachineFollowZoom`, `CinemachineRecomposer`) to a `CinemachineCamera` GameObject, resolved by type name. The type is validated to derive from `CinemachineExtension`.	generated-by mcp-plugin-dotnet

Cinemachine / Add Extension

Add a Cinemachine extension component to a CinemachineCamera GameObject. Extensions augment the camera pipeline (collision avoidance, framing, post-processing, etc.).

Inputs

• gameObjectRef — the GameObject hosting the CinemachineCamera (required).
• extensionTypeName — the extension type name. A full name like Unity.Cinemachine.CinemachineDeoccluder is preferred; a bare class name like CinemachineDeoccluder is also resolved against the Unity.Cinemachine namespace as a fallback.

Behavior

Resolves the type, verifies it derives from Unity.Cinemachine.CinemachineExtension, adds it to the GameObject, marks the scene dirty, and repaints. Throws if the type cannot be resolved or is not an extension. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool cinemachine-add-extension --input '{
  "gameObjectRef": "string_value",
  "extensionTypeName": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool cinemachine-add-extension --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool cinemachine-add-extension --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name	Type	Required	Description
gameObjectRef	any	Yes	Reference to the GameObject containing the CinemachineCamera component.
extensionTypeName	string	Yes	Extension type name, e.g. 'Unity.Cinemachine.CinemachineDeoccluder' or 'CinemachineDeoccluder'.
