    How to enable Chaos in 4.23

    Follow these steps to enable Chaos in 4.23 (new documentation)

    NOTE: This will enable Chaos for all of your Blueprint and C++ projects. If you'd like to enable Chaos per project, you will have to add the new target lines to your project's Target.cs file and create a C++ project (it won't work with a Blueprint project).

    Follow these steps to open the Chaos Destruction Demo:

    1. Download the Chaos Destruction Demo from the Learn tab on the Epic Games Launcher.

    2. Download 4.23 from Github (source build is required until Chaos is out of Beta).

    3. After you setup your GitHub build (you don't need to compile it), move the ChaosDestructionDemo folder into the same folder that you unzipped the GitHub build to.

    4. Run GenerateProjectFiles.bat.

    5. Open the created UE4.sln.

    6. Build the ChaosDestructionDemo for Development Editor (should be the default Visual Studio configuration). This will build the whole engine, with Chaos, since it's already setup in the project's Target file.

    NOTE: If you want to create your own project, you will have to follow the steps outlined in the "Follow these steps to enable Chaos in 4.23" section.

    7. Once it's done, you can launch the sample from Visual Studio with F5 (or Ctrl+F5, which will launch without debugging attached).

    NOTE: If you don't have the Epic Games launcher installed, this will be the only way you can launch it. Double-clicking the ChaosDestructionDemo.uproject will not work (you'll get an error message).

    8. If you do have the launcher installed you should be able to open it by double-clicking the uproject.

    Break all the things!

    DarkS474 I am quite sure Epic has great plans on applying Chaos on Fortnite aswel. For next gen console and PC it will work great and I am sure mobile devices will have no choice, but get even more powerful, so all fit into Fortnite purposes on expanding and getting new features. I don't play Fortnite (never tried, but watched videos) but I am sure I will when they incorporate Chaos there, just to feel how it goes on different platforms.

    That's good to hear.
    I am forced to keep going using PhysX but making BPs for runtime mesh swapping ready to add Chaos Geometry Collections and then disable the PhysX version. If UE 4.24 will have Chaos included with no need to compile from source I might start adding it to my project as long as the API won't then change too much. I still got a lot of work to do but I hope to be able to complete my first game next year probably in the 2nd half (if anything goes wrong I would have to postpone again...being a solo developer with a very small budget I can't do miracles unless a day started being 96hours+ here on Earth) and I will really need to have Chaos instead of PhysX for obvious performance reasons.

    Is this your first time building from source? Because if it is, you might be missing some modules at Visual Studio that are needed to compile UE4. At Visual Studio Installer check if all modules under "Game Development with C++" are checked, Windows 10 SDK and if all .Net Development Framework are checked aswel.

    I don't know about anyone else, but when I try to access the Unreal git, period, the page can't be found. I've connected and downloaded source files before, but its just not there as of today.

    For what's it worth, I had trouble too with the build complaining about a missing file when downloading the 4.23 release zip from GitHub, but it worked for me when I cloned the whole repository using git instead of downloading the zip and checked out the "4.23.0-release" tag before building. I also think I used Visual Studio 2017 rather than 2019, because I had had some trouble with building the engine with 2019 before (although I can't remember the specifics on that).

    You need to make sure you got the source pinned for UE4.23, so at GitHub click on the link called "releases" and there you will see the sets for each release for UE4 where you can select any unpatched release aswel. Make sure you download the release 4.23, because you if don't do this and just get the current set at the repository, you will get recently pushed files and it won't match the release at all.

    Is there anyway to increase hitting force of the shooter in Chaos? What BP do I use?
