How to Use?
You can add nodes directly in the Node Editor using the Add menu (shortcut: Shift + A), or drag them from the Asset Browser into the Node Editor.

Nodes with blue icons represent geometry nodes, while nodes with other colors represent shader nodes.
For motion text presets, simply drag them into the 3D Viewport and adjust their parameters in the Modifiers panel.
If you can't see the text in the viewport, try moving the timeline to view it.

In addition, there are many use examples available. You can explore their node setups for learning and reference.
In Blender 5.0, assets are imported using Pack mode by default, which prevents user editing. To edit them, go to Object → Relations → Make Local… → All to localize the asset, or change the import mode to Append
