This wont solve renaming issue but it might help you switching up to new renamed module
Copy code module (folder in Source) from old project and then edit uproject file (in text editor):
"Modules": [
{
"Name": "RenamedProjectModule",
"Type": "Runtime",
"LoadingPhase": "Default"
},
{
"Name": "CopiedOldModule",
"Type": "Runtime",
"LoadingPhase": "Default"
}
]
and both *.target.cs files of new project
ExtraModuleNames.Add("RenamedProjectModule");
ExtraModuleNames.Add("CopiedOldModule");
…to add new module from old project
Now regenerate project files and build, this should make old blueprint work as old nodes will be active in new project and you can swap nodes and reparent . Ofcorse there might be issues if you got classes with same names in both modules
And in the way you learned how to make new modules which might be useful knowledge in future:)
