So why exactly did we need the engine upgrade to get weather?

so one of the things we really wanted to do with weather is to have dry factories like if you're inside that you don't get wet there are many ways of doing that but we wanted to do the scene capture method in Unreal which was promised to be more efficient with future updates and that wasn't there yet when we initially looked at it so with five point

free, it finally became more efficient, and then with 5.5, 5.6, it was fully there.
