I’m trying to compile a specific commit from the unreal engine github. I’ve also tried compiling versions close to the one i need, yet nothing helps. I have a project for this version, and i don’t want to lose it. Help would be much appreciated!

Hi there @Clixxzy

Welcome back to the forum! I went to check out the link. But, it’s showing it doesn’t exist?
