How to enable Chaos

[MadesTV]

Hello I have tried several time to build and use chaos on 4.25 release build but no matter what I try it always fails I have added both bCompileChaos = true; bUseChaos = true; and also change .shared to .unique and have tried to follow https://www.youtube.com/watch?v=1lfSFlMEwbE comments to no avail but it still does not launch after building the engine I get the Shader type was loaded after engine init, use ELoadingPhase::PostConfigInit on your module to cause it to load earlier. error how do I fix it. Thanks

I commented out that line and rebuilt (points it out when fails), works OK for me.

I not getting this error now im getting this NightmareEditor modifies the value of bCompileChaos. This is not allowed, as NightmareEditor has build products in common with UE4Editor. and I created it with the built engine

I've also been unable to get Chaos to work with 4.25. I also get the error message that Terrian get and have been unable to fix it. It feels like a rather small issue since it's something that's declared twice, but haven't been able to find where it's declared at all thus far...

Has anyone tried with the 4.25 Plus branch to see if that works?

Watch this video https://www.youtube.com/watch?v=1lfSFlMEwbE Look at the comments. I did it with 4.25 source. In 4.25 Chaos is faster and easier to use.

I did manage to finally compile the engine from release branch and launch the project. But now it looks like the fields are completely ignored in all example maps. Can anyone confirm that fields are working for them? Additionally engine version for the project is 4.24 some why, even though I compiled 4.25 from release brunch

You need to merge your accounts to get access to the UE repositories. Detailed instructions can be found here: https://docs.unrealengine.com/en-US/...ine/index.html

I'm getting the same thing. Using the release zip from the github site.

I figured it out, you have to follow the guide in the OP, not in the documentation.



Important points not present in the documentation page:

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

2. Download Unreal Engine 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.

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

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

Hi, I failed to open Chaos Demo in 4.23, and now I tried to build with 4.25 but I'm afraid to fail cause I can't download source code even I've connected my account to epic.

Can anybody download source code from github??? Why I can't do this? the page shows 404

so Can you help me to download some additional files to open chaos? I'd like it to work on 4.23 version at least

I have down loaded it and the compiled version 4.25 is great. https://www.youtube.com/watch?v=1lfSFlMEwbE&t=2s

Can I ask some detailed info on how you managed to get it to compile?
Whats your build environment and process?
What windows version?
What Visual Studio version?
Are you using the release zip, or a checkout of the 4.25 branch?
What were the config changes you made to enable the chaos features in the custome build?
Any other info.

The documented method of enabling Chaos ( editing UE4Editor.Target.cs as explained here ) just doesn't work for me on 4.25 from Github.

When I build the engine without Chaos, everything is fine and the Editor starts normally. But when I enable Chaos and build again, this error pops up when the editor starts.
