This is just a general gripe. It used to be that every developer library came with a comprehensive programmer’s guide and a reference guide. This body of documentation has neither in comprehensive form. It makes the product inaccessible, and learning curves are steeper than they should be. This mass of documentation has a hierarchy but no coding topics I have found are completely documented nor do you even learn where the real relationships between a code module and the rest of the engine are. There’s no index, and no organized single table of contents. In the mean time, the product expands on a serious curve that requires devotion and experimentation to keep up.
The videos are horrible and are basically narrating actions taken in a particular example. Examples like this do not convey real training.
Release management is so bad, I’m seeing a lot of empty space, and some API items are simply noted with “this was removed.” Not the version, the replacement, a workaround, or a reason.
I’ve bought several books on UE but none more than starter books. And these are useless for real development.
Unreal Engine deserves a masterful multi-disciplined technical writing team headed up by some seriously experienced folks. The best massive documentation effort I’ve seen is intel’s architecture document set. 10 volumes, last I checked. Both guides and references, but the documentation is COMPLETE, which is very important when writing assembly language for multiple processors.
