+
+MaterialConfiguratorPlugin adds a UI to configure and switch between different material variations.
+
+The variations of materials are mapped to material names or uuids in the scene.
+These variations can be applied to the materials in the scene. (This copies the properties to the same material instances instead of assigning new materials)
+The plugin interfaces with the picking plugin and also provides uiConfig to show and edit the variations.
+This functionality is inherited from [MaterialConfiguratorBasePlugin](https://threepipe.org/docs/classes/MaterialConfiguratorBasePlugin.html).
+
+Additionally, this plugin adds a simple Grid UI in the DOM over the viewer canvas to show various material variations and allow the user to apply them.
+The UI can also be used in the editor to edit the variations and apply them.
+
+To use, simply add the plugin in the viewer and configure using the created UI and UI Config. Note that `PickingPlugin` is required to be added before this to allow configurator.
+
+To create a custom configurator UI, use the `MaterialConfiguratorBasePlugin` directly and call the function `applyVariation`, `getPreview` and `addVariation` to apply and add variations respectively.

+[Source Code](./plugins/configurator/src/SwitchNodePlugin.ts) —
+[API Reference](https://threepipe.org/plugins/configurator/docs/classes/SwitchNodePlugin.html)
+
+SwitchNodePlugin adds a UI to configure and switch between different different object variations within a switch node object.
+
+This plugin allows you to configure object variations with object names in a file and apply them in the scene.
+Each SwitchNode is a parent object with multiple direct children. Only one child is visible at a time.
+This works by toggling the `visible` property of the children of a parent object.
+The plugin interfaces with the picking plugin and also provides uiConfig to show and edit the variations.
+It also provides a function to create snapshot previews of individual variations. This creates a limited render of the object with the selected child visible.
+To get a proper render, its better to render it offline and set the image as a preview.
+This functionality is inherited from [SwitchNodeBasePlugin](https://threepipe.org/docs/classes/SwitchNodeBasePlugin.html).
+
+Additionally, this plugin adds a simple Grid UI in the DOM over the viewer canvas to show various material variations and allow the user to apply them.
+The UI can also be used in the editor to edit the variations and apply them.
+
+To use, simply add the plugin in the viewer and configure using the created UI and UI Config. Note that `PickingPlugin` is required to be added before this to allow configurator.
+
+To create a custom configurator UI, use the `SwitchNodeBasePlugin` directly and call the function `selectNode`, `getPreview` and `addNode` to apply and add variations respectively.
