Build for Windows when working on Mac

Hello!

I am starting work on a cross-platform game, to be built for both Mac and Windows (as well as IOS and Android). I have found that when working on Mac, I cannot build for Windows. Would the best course of action for achieving a Windows build (while working on Mac) be to open the same Unreal project from Windows and to build from there, and how much optimisation would the project need to undergo when switching from Mac to Windows?

For example, I read that for a purely blueprint project the transition should be seamless, but any C++ code may need to be reconfigured. Is this the case? Thank you very much!

I’ve used Mac and Windows builds for my game. But I had to build both in their own operating system. You cannot build Windows on Mac, and vice versa. You can build Linux from Windows though.

I had my projects on git, and all worked fine. Just used git pull when I needed to update stuff.
