+ Multiple Models.
+ Load and control multiple 3D models within a single <model-viewer> canvas.

+
Interact with Multiple Models
+
+ By placing declarative <extra-model> elements inside
+ <model-viewer>, you can load multiple separate 3D models into a single scene.
+ Each model has its own position offset, orientation, and scale, and can be manipulated
+ individually.
+
+
+ This example displays three models, each showcasing a different type of interaction:
+
+
+
Sphere (Base Model): Changing material base color factor dynamically.
+
Robot (Extra Model 1): Targeting animation play/pause to a specific model index.
+
Astronaut (Extra Model 2): Animating the position offset of a model over time.
