Knowing issues:

  1. At this time Navifation tree (left panel with TOC) working correctly only on Firefox browser. (in Chrome for example it’s just looks like empty space). I don’t have any experience in web development and can’t fix this issue. Maybe fix this in future. Anyway in Firefox all works fine (in most cases).
  2. If you open any seperate page (not index.html in root directory) navtree also dont be vidible.
  3. All pages in folder \docs.unrealengine.com\en-US\Editor\ looks buggy, but they all have a working copy in other places. I save this folder just in case, buy you can delete it.
  4. Some features, like searching not avaliable.
  5. Next pages in API reference is missing: (Bad Gateaway error)

Thanks for sharing this! Curious how you went about doing this, was it using HTTrack?

Yes, I’m using HTTrack for downloading site. I don’t know why, but HTTrack can’t detect navTree.html page and you need save it manually. Nothing special.

Awesome! Thank you for sharing!

The NavTree and search bar are Broken(I download the Full Doc with API version),I’ve test it in Chrome and FireFox( I’ve try FireFox 68.0.1 and 69.0.3).

Thank you!

Hey [USER=“194378”]Mr. Deadline[/USER] can you please share your httrack preset, so we can update the docs?

I was interested in getting this going again. Every year I need an up-to-date copy of the offline documentation for use in the GDC TrainJam and end up recreating the wheel in the process!

Here’s what I found worked pretty well for httrack:

The real problem is that much of the web site will refuse to load and run if you just open the files directly in a browser (the classic can’t load file: from file: rejection that protects against virus-like activity). To get around this you MUST start a local server and serve the files. There is no good alternative any more with modern browsers made the way they are.

To this end, I have created a little project that automates all the scraping and will run the server. You can check it out here: https://github.com/Olliebrown/UE4DocScraper/tree/master

It is WIP and your mileage may vary but just in the spirit of sharing!

Is this a way of installing UE4 offline? If so it seems I cannot find an installation file like UE4.exe?

The download speed is too slow. Can you upload the file to a server in China?

Thank you very much. this is important to the way i work.

Hey Unreal! I am currently learning unreal’s c++ but unfortunately, after the update, a lot of c++ api pages won’t work. I just wanted to ask that by what time will all the pages start working again. Thank you!

I just download the pages themselves using share-print-save PDF on my phone. It labels it well and is uncomplicated. I hope they do a html manual like Blender does with the links all working because loading page after page is so data intensive and data is money, lots and lots of money.
