Reflection Metadata

Note:This page has been written for users running the Windows Operating System in mind. The process is presumably similar for Mac users.
This page is about the Reflection Metadata and its uses. For the actual file used on the wiki, see API:Class_reference/ReflectionMetadata.

What is the Reflection Metadata?[edit]

The Reflection Metadata is a special XML file that can be found in Roblox Studio's directory folder. It stores configurable information about classes.

To be more precise, it controls the following:

  • The visibility of objects in the Explorer window
  • The icons of objects in the Explorer window and Advanced Objects window.
  • The visibility and summary of classes & members in the Object Browser window.

Locating the Reflection Metadata[edit]

As stated earlier, the Reflection Metadata is located in Roblox Studio's directory folder.

To find this folder, you'll want to find a shortcut to Roblox Studio on your desktop. Once you find it, right click on it and press Open File Location.

In this folder, you should see a file called "ReflectionMetadata.xml".


If the file is only labeled as "ReflectionMetadata" with no extension, you may want to change your settings.

Importing the Reflection Metadata[edit]

Just a disclaimer before you start editing: You need to be very careful.
If you incorrectly edit the ReflectionMetadata, it can cause the Explorer to stop working, and it could potentially crash Roblox Studio.

With that said, lets begin!

While you could just crack open the .xml file and manually edit it from there, thats kind of a tedious process. Instead, lets actually insert the file as a model!

  • Right click on ReflectionMetadata.xml
  • Press Copy, and then paste it somewhere you can easily navigate to.
  • Rename the file to ReflectionMetadata.rbxmx
  • Go into Roblox Studio, and open a new place.
  • Right click on the Workspace icon.pngWorkspace and press "Insert from File..."
  • Navigate to the ReflectionMetadata.rbxmx file, select it, and press Open.

You should now see two objects in the Workspace icon.pngWorkspace.

When you open them, you'll find a ton of objects pertaining to classes, enums, members, and more!


The Reflection Metadata currently makes use of the following objects:

To give you a pseudo idea of how these classes are actually used together:

  • Tree-collapse.png
    • Tree-collapse.png
      • Expand.png
  • Tree-collapse.png
    • Tree-collapse.png
      • Tree-collapse.png

        • ReflectionMetadataMember

      • Tree-collapse.png
        • ReflectionMetadataMember
        • ReflectionMetadataMember

Editing the Reflection Metadata[edit]

Disclaimer:Modifying the Reflection Metadata is not supported by Roblox.

For the purpose of focusing on actually making changes to an object's visibility and icon, lets just focus on the Pages.pngReflectionMetadataClass object. This object has several properties, and we'll go over all of the important ones.


This controls the icon of the class, depending on its index value.
The index value must conform to 0 <= index <= 91, or else the Explorer will crash.
The following is a list of indexes, and what icons they correspond to:

This controls how classes are sorted in the Explorer. Classes with lower numbers are displayed more towards the top of the Explorer, while classes with higher numbers are displayed more towards the bottom of the Explorer. If its value is -1, this object is invisible to the Explorer.


Toggles whether or not this class can be seen in the Object Browser.


Toggles whether or not this class is Deprecated.


Sets the class that this class wants to be parented to, if added from the Advanced Objects window without the user selecting anything. This can be set to multiple classes if the string uses multiple lines.


Toggles whether or not this object can be inserted through the Advanced Objects window.

Saving the Reflection Metadata[edit]

Once you've made all of the changes you like:

  • Select both the Pages.pngReflectionMetadataClasses and Pages.pngReflectionMetadataEnums objects that are in the Workspace icon.pngWorkspace.
  • Right click them, and press Save to File...
  • Save them to the .rbxmx file you opened earlier
  • Rename the file to ReflectionMetadata.xml
  • Delete the existing ReflectionMetadata.xml file in Roblox Studio's directory
  • Paste the new ReflectionMetadata.xml in its place.

Keeping a modified Reflection Metadata file persistent[edit]

One of the annoying things about modding the ReflectionMetadata file, is that Roblox Studio likes to verify and overwrite modified files when the launcher is ran.
To work around this, CloneTrooper1019 wrote a 3rd party mod manager for Roblox Studio.
It provides you with a separate folder that has a similar structure to the one seen in Roblox Studio's folder directory, and when the launcher is ran, it will directly run the main program rather than the launcher.

The launcher will only run when Roblox Studio has to be updated.
