Bulk Rename tool for Unity allows for quick and safe renaming of many assets or GameObjects. It provides several ways to rename Objects including the ability to replace substrings, add prefixes and suffixes, add numbers, and delete characters from the front or back of the name of each Object.

To install this package follow these steps:

1. Download the latest package from the Releases page. (Or click here)

2. Open the Unity project you want to import the Bulk Rename tool into.

3. Install the custom package through Unity's Asset menu.

• In Unity Editor go to Assets -> Import Package -> Custom Package...
• Select the .unitypackage file you just downloaded. We recommend storing the files at the default location (Assets/RedBlueGames), but it should work anywhere.

To use the Bulk Rename tool you must first select the assets or GameObjects in a scene you want to rename. Right click, and select "Rename in Bulk". This will open up the rename utility. You can continue to select or deselect Objects while the tool is open.

The tool allows for the following options:

• Search String and Replacement String allow for replacement of substrings from the selected objects.
• Example: The name "Char_Hero_Idle" with search string "Hero" and Replacement string "Enemy" would yield "Char_Enemy_Idle".
• Prefix and Suffix additions allow you to add prefixes and suffixes to the start or end of every object.
• Example: The name "Hero" with the added prefix "Char_" and suffix "_Idle" will yield "Char_Hero_Idle"
• Trimming allows you to delete a number of characters from either the front or the back of the object's name.
• Example: The name "CHairA" with 1 specified to Delete from Front, and 1 specified to Delete from Back with yield "Hair".
• Enumerating allows you to add sequential numbers to the end of each object name. This will be added after the deletions or suffix additions.
• Example: Selecting 3 objects that are all named "Wall", and specifying "00" or "D2" as the format string, and a Starting Count of 0, will yield "Wall00", "Wall01", and "Wall02".

You can use some or all of these options when renaming your assets.

Below these options there is a Rename button, which will rename all the selected assets according to the settings. Below this there is a preview of the results, which includes a diff of the original name, and the resulting name. Entries in bold will change, others will remain unchanged.

Currently the tool does not allow for undoing Assets, (though Undoing GameObjects in the scene is possible). This seems to be a limitation of Unity's undo system.
