Thank you so much for looking into this!
DumpCVars is good for the general search of values, but it doesn’t have their descriptions - it was the main use of help for me - as a way to research to research kind of hidden unreal features.
Unfortunately, at the studio I’m working we use only official builds, so we won’t be able to get by recompiling. It would be great if the fix can be backported to 5.6.x.
