Adds a FullBodyBipedIK component to a character GameObject and auto-detects biped bone references. The character must have an Animator with a humanoid avatar, or a standard biped bone hierarchy. This is the main IK component for bipeds — controls hands, feet, body, and shoulders.
unity-mcp-cli run-tool finalik-add-fbbik --input '{
"targetRef": "string_value",
"autoDetect": false
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool finalik-add-fbbik --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool finalik-add-fbbik --input-file - <<'EOF' {"param": "value"} EOF
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.
