Creating Custom Master Files

Overview

For large scale projects it may become necessary to make use of custom Master File (.esm format) for user-created plugins to refer to. This is particularly useful for projects involving new world spaces or circumstances that require multiple people developing simultaneously. This tutorial will present a method for doing just that.

Creating the Master File

In order to create a Master File, you must convert an existing Plugin. The following is a step-by-step procedure detailing this process:

1. Simply rename the ".esp" extension of the Plugin file, that you want to convert to a Master File, to ".esm"
   • I ended up using an FTP program known as FileZilla for this, but you can do so through a variety of other means such as Command Prompt.
   • To use Windows Explorer to do this, go to Organize > Folder and Search Options > View > Hide extensions for known file types. Uncheck the box. For more details and for pictures, follow this link: http://www.mediacollege.com/microsoft/windows/extension-change.html
2. Open the Creation Kit and load the ".esm" data file you have just created and then save it.
   • This in order to have the Creation Kit recognize it as a true Master File.

Referencing the Master File

If you expect to have a Plugin reference the Master File: open both the Master File and Plugin (as active) and simply re-save your Plugin. It is strongly recommended that you back up your original Plugin in case you do something wrong. Like if you realize you did not want your .esp to reference a particular Master File.
