How to enable Chaos

[Justo]

I think this tech is truly exciting, and as an artist I'd love to invest my free time into learning more about this. It is surprising (and a tad disappointing) to see the lack of material out there, or contact from Epic people in regards to this tech (or at least that I'm aware of). As far as I know, this was and still is being promoted as a relatively important component of UE4, much like Niagara and new animation systems.

Isn't it a bit ridiculous that several engine versions later, it is still a cumbersome process to make this destruction tech even work? Are there any people in Twitter making Chaos experiments, or anywhere else where there is more info relating to this besides the initial GDC and Twitch/YT livestream talks? Any plans for the future to integrate this into the main UE versions downloadable through the Epic Launcher, or any simple environment using this technology?

Does anyone know of any external forums maybe (much like Polycount or BlenderArtists do for their own community) where the Chaos Engine is a popular topic? People that are working with this and showing their results?

theProfessor where did you upload those rar pieces of the compiled engine? Those YT links don't show any links either.

I haven't uploaded them yet. I have Google Drive(15gb). There 4 files 10.5 gb(3). Do you want them? I would have to put them 1 at a time on my GD. Do have a drive that is bigger?

That may be against Epic's EULA's?

Anyway, following the steps I've gotten 4.25.1 to work just fine with Chaos. You might as well just wait though, it's very slow and buggy at the moment. You may have better luck with the dev branches as they are continuously improving/working on Chaos related stuff in those branches.

Edit: In fact, if anyone's still having trouble. Just make sure you have the latest 4.25.1 source code built with the stuff from the first post added to the UE4Editor.target.cs and create a new blank project with no starter material. Then just copy over the content folder from the chaosdestructiondemo project to your new project and start it up. It may say something about rebuilding the project, just click no as that seems to be broken, it should still load up fine for you to test.

When try the Chaos project and give the path for the compiled version it doesn't load and execute the project. Not a big deal because I have a compiled version of 4.25 working. I was bored yesterday.

It doesn't work, I've compiled everything. It took almost 20 hours to finish, I enabled the plugins, and nothing; Not even the Chaos Editor button appears.
It is very frustrating, can someone help me?

Feel free to use this thread for discussions related to Chaos. We appreciate your feedback!

I noticed if you try and open the chaos demo from the launcher it errors after setting it up.
the workaround is to show in folder and then rightclick the uproject file and switch engine versions to the source build.
its not setting its self to the souece build unless you manually set it. Just an FYI <3

when you get the source make sure you get the 4.25-plus



and when you extract it some reason if you use winrar it extracts as a folder in a folder.
you need to make your folder structure look like this

Chaos NOOB guide with pictures.


Please refer anyone not getting it to work to this post.

step 1 download the source from github.(make sure to get the branch 4.25-plus) NOTE: i tried with all 4.25 branches. 4.25-plus is the one that i got to work.
none of the other branches seemed to compile so now you know the secret.


extract that to the ROOT of a drive and make sure it does not have a folder in a folder like

d:\ue4\ue4 otherwise adding the demo project wont add it to the right location add it to the folder you extracted as victor said will not put it in the right folder. so cut and paste the files
to be in the root drive in a folder. i named mine UES4.25 this stands for unreal engine source 4.25

after that in the launcher make a destruction demo project for 4.25 DONOT CHANGE THE NAME......
now move that folder once finished inside your UES4.25 folder and you will see this below



Now find the file called UE4Editor.Target.cs (most important step here)
make it say the following code add the 2 red lines below to that file

// Copyright Epic Games, Inc. All Rights Reserved.

using UnrealBuildTool;
using System.Collections.Generic;

public class UE4EditorTarget : TargetRules
{
public UE4EditorTarget( TargetInfo Target ) : base(Target)
{
Type = TargetType.Editor;
BuildEnvironment = TargetBuildEnvironment.Shared;
bBuildAllModules = true;
ExtraModuleNames.Add("UE4Game");
bCompileChaos = true;
bUseChaos = true;
}
}

SAVE THE FILES CHANGES then proceed below



now click on setup.bat, it will take a while to download dependencies depending on your net
speed it can take a while.

WAIT till the download finishes and the command prompt closes
before you proceed below

after the prompt goes away then click generateprojectfiles.bat. it will then add a few things and an UE4.sln
it may just be called UE4 if you have file extentions hidden like windows does by default.
now open the UE4.sln it will load visual studio.

if you DONT see chaos destruction demo in visual studio like in this image below then your chaos demo folder is not in the right place.



click at the top where it says build like in this image and click build solution



let it build. it will take an hour or 3 or 15 hours depending on the paper weight PC you are using. :P

after that is done goto the destructiondemo.uproject file
rightclick it and goto switch engine versions and switch it to the source build of 4.25



after that is done click the project file and it will run! bing bang boom now in the editor modes you have chaos








GG you GOT IT!

HERE is your step by step guide, now don't choke on the silver spoon feeding please :P
