# Custom Asset Editor

Definitions open in a custom `FBaseAssetToolkit`-derived editor with:

| Panel              | Description                                                         |
| ------------------ | ------------------------------------------------------------------- |
| **Details**        | Standard property editor for the definition and inline fragments    |
| **Fragment Graph** | Node-based visual editor showing fragment hierarchy and connections |
| **3D Viewport**    | Live preview of all spawned mesh components using sync loading      |

The graph editor persists node positions via `UModularAttachmentFragment::EditorGraphPosition`.
