At the bottom the following 3 lines of text are just text and don’t link to anywhere.

Same issue with this page:
except the text is.
Beginner
Intermediate
same issue with Firefox and Edge
If I use ctrl-click on links to open in new tab, the target page opens up a page with a content bar expanded on the left. The content bar is not closeable; I have to ctrl-R reload the page to make it go away. This happens for about 90% of the links I click – it’s not actually 100%, which is even weirder!

It’s the first time I’m reading the documentation and I spotted this error on the page linked below. There’s a section related to the World and it’s missing the image and the link by the end of the text description seems to be broken.
Hi,
So many images files are missing from documentation and instead of the image embedded this kind of texte shows: !](Shared\Icons\icon_SaveAsset_40x.png)
I don’t know if EPIC is aware of this.
The following page doesn’t exist but the editor opens this tab automatically when I try to package my game for IOS.
I really wonder what was written there.
i hate this it wont let me play fortnite or any other games i downloed
some documentation is broken for Firefox:
this page is unreadable. i had to switch to edge
Hey
Video is not playable

Thanks, Nooxet! The normal Git Pull request procedure should apply here, you’d just be submitting comments instead of the usual bug fixes or new features. Our API reference is generated based on code comments, so yours would be included the next time we update the API ref, which is typically once per major release.
As a side note, have you considered using Epic Online Services (EOS)? EOS is sort of “OSS 2.0”, and it does a lot of really powerful stuff. In case you’re interested, here’s the top page, and the top-level documentation page for EOS. It also has its own API reference, samples, and thorough documentation.
You can find more information about contributing to the engine here: https://docs.unrealengine.com/en-US/…eal/index.html
If you’d like to write snippets of sample code that we can use on specific API reference pages, instructions for that are here: https://docs.unrealengine.com/en-US/…ets/index.html
And this page tells you how to get the latest engine code from Epic: https://docs.unrealengine.com/en-US/…ets/index.html
Thanks again for your interest in our API reference!

Thanks for your reply, I will be making pull-requests soon. I had not seen the EOS system, I just got OSS to work, but it definitely looks interesting so I might indeed rewrite some stuff 
I would also be happy to provide example code, as I often search for it myself when trying to understand how the engine works.
Cheers
In this page:
The functions InitBoxExtent and SetBoxExtent have the descriptions interchanged I think.
An observation, offered in the hope it’s constructive:
The danger with code-extracted documentation is that it kinda looks like documentation, but sometimes, it really doesn’t fill the actual written documentation needs.
This is the essence of auto-generated documentation with great style, and zero content.
What does it mean to have keyboard focus? Is keyboard focus different from just “focus?” Can this function fail, and if so, what happens? What are the pre-requisites for using this function, and why would I want to use it?
If there at least were some breadcrumbs and “see also” on these documentation pages, it might save the situation, even if you can’t actually go in and write good prose for each and every function there is (which would be a lot of work, understood!)

**Material Instance Parameters**
These are palced in a material uniform buffer where any draws using the same Material Instance can merge.
According to the documentation Play In Editor Settings | Unreal Engine Documentation there should be a setting for Standalone Window Size.
However in 4.26 it seems to be missing, I see only three settings. I can’t find no explanation anywhere. 
unreal engine dont open because wmfmedia, what is the problem please!
Usually the documentation work fine and it’s amazing! But now I’ve been trying to follow this doc for hours on end and it just doesn’t work. My computer was clean formatted, I tried on unreal 4.25.4 and 4.26, neither worked. Also I don’t get the same packaging options in my project, I don’t have ETC1.
I fine combed the documentation, I’m inclined to think it needs a revision!

No worries @echo_four, yes right-click works for me. Thank you!
Hi,
Page: Referencing Actors, paragraph “Direct Blueprint Communication Referencing” after executing all the steps from the example expected result was reached, but with errors.

Thx <3
I was trying to find some C++ documentation for physical material, and the two links I found does not seem to work:
https://docs.unrealengine.com/en-US/API/Runtime/Engine/PhysicalMaterials/UPhysicalMaterial/index.html
https://docs.unrealengine.com/en-US/API/Runtime/Engine/PhysicalMaterials/UPhysicalMaterial/DetermineSurfaceType/index.html
https://docs.unrealengine.com/en-US/API/Runtime/Engine/PhysicalMaterials/UPhysicalMaterial/SurfaceType/index.html
After some digging I found this link:
which in turn leads me to
which seems to be what I am looking for. But, again searching the docs led me to the links at the top which is not working.
This seems to be just a simple redirect, or just updating the links and replace “Engine” with “PhysicsCore”
Thank you!
Hello! just reporting some broken links to your png files. (near the bottom of the doc)
