Hi @Tim_Hobson @AJ_Graphix @PhoenixMarket and to you all who have been supporting this topic.
I want to give a mention of the new UE 5.0, Currently Early Access 2.
In this version, your UE4 favourite function has been moved
Developer Tools > Widget Reflector, but I can’t find this setting in UE5
In UE5 The answer is to use the key sequence together of “Control + Shift + W”, the first thing when your project blueprint has opened up.
So There is a new UE5 thread Is it possible to change the size of the font of the UI for a high DPI monitor? - Unreal Engine 5 Early Access / Feedback for Unreal Engine 5 Early Access - Unreal Engine Forums
Which I hope will help you, thanks for all the work
I found this using my skill of searching and reading the source code, but this will never match your artists skill to produce these wonderful projects.
