# One-Click Tool to Regenerate Remember IDs

Persistent Instances includes a simple editor tool that allows you to **regenerate Remember IDs for multiple GameObjects at once**.

This is useful if you have **placed or duplicated many prefabs in a scene** that contain **Remember components**, which may result in duplicate IDs.

#### How to Use

1. Select the **GameObjects or their parent** in the **Hierarchy**
2. Go to **Game Creator → Regenerate Remember IDs**

The tool will regenerate the **Remember IDs for all selected objects and their children**, making it easy to update large groups of objects at once.
