Here’s how to rename a plugin, a module or move content and classes between two plugins without breaking your blueprints in unreal engine.
I usually write down anything that i spend more than 15 minutes trying to figure out. For this case i spent about an hour and almost rewrote my blueprints from scratch. I’m going to keep this short but it should help.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

1. Move your content to the New Plugin<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

If you’re merging two plugins , you’ll want to move the content from the old\/source plugin to the new\/target plugin in the editor first. This is the easy way of doing this.
If you’re writing a script and automating this process, you can move the files and add CoreRedirect. More on this in the example config file below but it’s basically
\u00a0+PackageRedirects=(OldName=”\/OldPlugin\/”, NewName=”\/NewPlugin\/”, MatchSubstring=true).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

2. Moving classes structs and enums between modules(plugins).<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

This part is very important if you don’t want to break your blueprints.\u00a0
In your new \/ target plugin’s “Config” folder… create\/edit a file called “PluginName.ini”… eg if your plugin is called “CoolPlugin” you’ll want to edit\/create “CoolPlugin.ini”.
Then you’ll you’ll want to add [CoreRedirects] defining what changed and where to find it now.\u00a0
Example file:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
