also rename the c++ parent class name
If I understand what you’re saying, you don’t need anything special for that. It’s just a find & replace within whatever IDE you’re using.
is there any way to automatically re-compile/save all .uasset files in Content dir?
The only way I know to do it is to run a commandlet: CompileAllBlueprints.
Sometimes it takes me a couple rounds of removing the redirector and compiling blueprints to find them all.
I’m not really an expert with commandlets so figuring out the best way for you to run one may involve some searching. Don’t know how good the documentation of that tool is.
