# Node Hierarchy

This feature empowers you to bring your webpages and videos to life with precise animation control over individual parts of your 3D objects.

**Node Selection:** Select a node from the left panel by clicking on the arrow and expanding all the nodes.\
\
**Animate on Timeline-** Using this option you can add the node to the animation timeline to animate them to create interactions.\
\
You can directly manipulate position, rotation, scale, opacity, and materials of specific object parts (nodes) using the timeline.\
