There are several methods for patching projects created in Unreal Engine 4 UE4. The method used here is platform-agnostic, meaning it technically can be used for any platform. However, the only two platforms that you would intentionally use this method with are Windows and Xbox One. Other platforms have specific patching methods. You can find documentation on these platform-specific methods in the section for the platform you are planning to develop for.

This method can eventually use a lot of data storage, because this method keeps all old files, and merely points the game to the newest files that exist. Platform-specific methods often use less space. In this example, we are creating a patch for the sample Shooter Game.

There are several methods for creating patches, but they all use one of two approaches. One approach keeps files from the original release or previous patches, but adds a pointer to new content.

The other approach is to transform the content in the original build using a binary patch. However, we do not support distribution of patches for your project. Each platform has their own system for uploading patch files, and for distributing those patch files to users. For information on these platform-specific distribution systems, see the documentation for that platform's Software Development Kit SDK.

There is a method for creating patches in Unreal Engine 4 that will technically work on any platform. This method packages the entire build with new content, while the changes between the two builds are placed in a sidecar file that is added to the original file. Windows uses the method described in Platform-Agnostic Patching Method.

I imagine that shouldn't really make a difference though. DG Gage 1. I don't think it would be easy to "patch" an android game, less probability if it is made with ue4.

No sorry. The only information i have seen regarding this were release notes from Epic. The advantages are obvious - you only need to ship these difference files which are essentially just patch files and usually very much smaller than the whole file - think binary differences - maybe googling for something like patch utilities may get you closer to what you want.

I tested it out directing the game to run on both Intel HD integrated laptop graphics and Nvidia dedicated GPU so it's not some incompatibility with either of those You could also try directing the game manually in the Nvidia control panel to use Integrated graphics and just see if anything changes. It will run it at 60fps if you have to go that route.

I don't know how to access an official repository for the Unreal Engine 4 source code to view, but it looks like this dude has a copy from years ago for some reason I do not know why those are there and why you have them, other people have them and I do not.

I don't know if this has something to do with having the Epic Games launcher I don't use it so I have no ideaif it has something to do with these games being installed on a separate drive E: Driveif you are some sort of game developer or what is going on there exactly. Perhaps someone hopefully on here besides me can tell us why the heck someone would even have any of that.

Beyond that, I would say that if you are a developer who uses Unreal Engine, there must be some way for you to download an update for it. I can't see how as I do not have an account.

I don't know if this has to do with anything, but it looks like there is a recent hotfix 4.

Why not just keep the wiki read-only online? Just to retain the old pages? I'm pretty lost right now without some of these articles and I don't understand why the only option you had was to completely disable it. Please think about opening it up again just for read. I don't care about the maintenance mode, but the wiki was an important learning point, which is now gone. Hobby game developer from Germany Follow me on Twitter!

Comment Post Cancel. Why take the wiki down before duplicating the information in other areas? Aside from the fact that scattered resources like forums, blogs and even UDN are nice as supplemental and no replacement for a community updated repository. At a bare minimum, could we get a dump of the wiki so the information could still exist?

Oh no! Is there no way of leaving the wiki up as read-only and, as you make the articles available elsewhere, forward to them? Reason I ask is because sections of the wiki are still the top Google answer for several questions, for example "UE4 On Particle Collide".
