This pains me to see. UE and in extension UEFN need a lot of improvement in terms of useability. There are simple things that take 10-20 clicks to do and 1-2 clicks in Unity.
Epic needs to put together a team and find those bottlenecks and add functionality in the engine that helps makes games faster, not only to run well. There is also a need to have a more lightweight version of the engine to be able to run on lower end PCs (5 year old ones cant run it anymore).
Lastly, shortcuts for doing things can be easily spotted if Epic asks gurus of each specialty what would speed up their workflows and implement hotkeys, tools and wizards.
Some examples on top of my head are:
Texture to material to mesh to blueprint workflow. Check both UE and Unity to see the differences, also compare them with simple 2D cases
Character animation and rigging. Still obscure and requires a lot of tweaking to get right
Extra menus and popups for things we don’t need and cant be turned off (Output log I am looking at you)
Weird quirks of file usage (everything has to have an underscore, be named without a number in front, wont import if file name exists in folder and doesn’t tell you)
Level design quirks that slow down development (attachments don’t get duplicated if the parent is duplicated, “replace” removes new actor from its folder structure, “Paste here” which is the most useful hotkey for level design doesn’t work by default and requires special setting in editor preferences, movement gizmo breaks when using them with grouped objects)
Please get a team together to fix ease of development, its way too slow atm and there is a lot of improvement that can be done. Lmk if you want a meeting to discuss more items like these
