I have a few ‘years’ of on and off blender experience, last 2 months, for the first time I dedicated my time to blender daily almost so alot of progression went up but i’m SO confused about certain things.

At the moment, I make random models or stuff for unreal engine, right now i’m working on modular assets, everything works fine until I get too complex.

Now see, the donut turorial gives alot of information for A, and some random uv unwrap tutorial does give some good information in B, but what the heck am I supposed to do outside of this range?

Almost all uv unwrap tutorials are based off of extremely simple objects which I can already do I feel like i’m either missing something because those tutorials give info about A and B but when I make more complex stuff than said tutorial I suddenly need abcde, last 3 being completely unknown to me, how do I uv unwrap a sub/modified model? How do I unwrap a beveled object? Do I just uv unwrap before I do the 2?
