Hi all,
That’s really a lot of different issues to address in one thread. I’d like to point out that we have a pretty thorough documentation setup to which we are constantly adding as the engine changes. Also, the Community Wiki is very useful for users to collaborate on answers and frequently seen issues. Lastly, we have an extensive video tutorial collection, made by Epic and by the community of users for you to peruse.
If you go through these resources and find that your questions still aren’t answered, we can take them one at a time and possibly put in feature requests for specific issues that have not already been addressed. Please be sure to check the forums, as many times devs will communicate on UE4 aspects that are slated to be added or at least discussed.
I hope this helps!
