Flag. Use buttons or wand to change bird to gold and back.
Used blender to render bird animation frames: one for real and a separate rendering for gold. Both animations run all the time, but commands make only one visible. Bird is on turbosquid, but isn't gold. Get a model or make your own, make any changes you like in Blender, then render bird with transparent background into several png frames. Make a separate one for gold.
