it's not hard and not that much work. there are tons of people making their own 3d engines for fun all the time. Usually they get something on the screen relatively quickly. There are articles and YouTube channels all over on how to do it. If you want to make all of UE5 then it's a lot of work but if you just want to display a pBR 3d model it's a day's work if you already know how and a few days if you don't rebuilding every feature of a 3d engine takes lots of time but getting to a lit model does not.
