How to enable Chaos

[theProfessor]

You're required to use a source build from GitHub until Chaos is out of beta.

I did get the source for 4.23.1 and did follow your instructions. I used the instructions for 4.21 - 4.23 and they all worked. Chaos OK. Is there any difference for 4.23.1?

Is chaos completely left out of launcher build or supported with some limitations?

Yes, it is totally missing.

I did something very similar lazysnake61 and Chaos did not function. So order66 what did you do to get it to work?????? Be explicit.

[lazysnake61]

-I dled the 4.23.1 release branch. Ran setup.bat.
-Downloaded chaos demo from the launcher.Copied the chaos folder into 4.23.1 folder which has folders named Engine,Intermidiate etc.
-Ran generateprojectfiles.bat . However, the UE4.sln file generated this way doesn't list chaos project in solution window.
-I had to go into chaos folder, right-click on chaos's uproj file and select generate visual studio files to creat chaos .sln file,opening which lists chaos project at bottom and UE4 project on top. I have tried building and running all three projects separately. (UE4 only, UE4+Chaosdemo, chaosdemo only)
- I have built successfully ( 0 errors or warning) in VS2019 using the 14.22 toolchain( latest toolchain has some bug.). All builds crash at 79% except chaos-only solution which crashes on 100% but doesn't launch the editor.

Use 4.23. Chaos is not in 4.23.1. Waste of time.

This is just ******** and a stupid thing to say... Don't listen to him. Chaos is in 4.23.1. and works fine!

[VictorLerp]

Chaos is in 4.23.1, and the "how to" instructions works for both 4.23 and 4.23.1. Make sure you grab the correct branch on GitHub!

So 4.23.1 does not have chaos but 4.23 does? Not sure what sense this is making. Did Epic pull back on Chaos beta?

[lazysnake61]

Whaaat! 4.23.1 has no chaos at all?

So I moved the chaos demo folder inside the ue4.23.1 folder (same one with engine,intermidiate etc folders). Ran generateproject.bat and opened the UE4.sln but there is no chaos demo listed ,only UE4?
I tried manually generating and building chaos VS solution and it shows UE4 on top and Chaos demo on bottom. So I built chaos successfully but it won't open the ue4 editor.

Anyone else having a crash when trying to Generate Geometry Collection Asset?

Crash log breaks at D3D11Util.cpp "UE_LOG(LogD3D11RHI, Fatal,TEXT("%s failed \n at %s:%u \n with error %s"),ANSI_TO_TCHAR(Code),ANSI_TO_TCHAR(Filename),Line,*ErrorString);" Line 249

This is on a Win7 machine, I saw one person having issues with Win7. Anyone able to get this system to work on a Win7 machine. Note I get the same crash log when trying to run the Chaos Destruction Demo, just fails to launch the project. My assumption is that there are created Geometry assets it's trying to load as it happens around the same % of loading.

chaos doesn't work on my win 7 machine either. it always crashes when trying to generate geometry collection asset.

[File:/engine/Source/Runtime/Windows/D3D11RHI/Private/D3D11Util.cpp][Line:249]

with error E_INVALIDARG

[lazysnake61]

So after moving chaos destruction demo inside ue4 directory and generating project files, should I build UE4 or only Chaos Destruction Demo solution?
