4.24 failed to build with Chaos enabled.

Any ideas how to fix this error?

Not sure why you’re getting that compile error (cannot convert argument), but perhaps the “Temporary license has expired” warning/error is due to you not being signed in to Visual Studio.

Nope, that’s message from IncrediBuild, that my Trial has expired, that’s don’t cause error.

Looks like others have same errors:

I face the same error in 4.24.1-release:

I have the same problem. Running under Debug Editor, I can’t compile the engine with bCompileChaos = true. I have to turn it off in order to get the engine to compile. I was running off of UE 4.23.0 and just upgraded to UE 4.24.1.

Hello,
Any progress about this, could anyone compile Chaos on 4.24.1?

dmon_shiver
I guess not.

Happy Christmas! And got any progress?

Got an answer from Epic Games, worked for me:

Thanks, It works.

Hey SkyDelete, where was this answer? Have looked over the AnswerHub and UDN and couldn’t find it.

Cheers.

The docs all point to 4.23. Unreal seems to change alot from version to version.

Have you found 4.24 to be an improvement over 4.23 when using the Chaos Engine?

Thanks!

dont work…i have write

bCompileChaos = true;
bUseChaos = true;

dont work hmmm…

This worked here.

In Source/ChaosDestructionDemo.Target.cs add:


bUseChaos = true;

I added


bCompileChaos = true;
bUseChaos = true;

Into my UE4.24.2 Editor target file…

Tried to compile Development Editor, Win64 ad UE4 as Start Project…

Always get this Errors… and Compiling failed… Any ideas?


Saying: C2106, “=” Left Operand has to be L-Value - in PhysInterface_Chaos.cpp Line 127

I have the same … after changing “Particles.Disabled” to “Particles.DisabledRef” on that line with the error then I can compile it. No idea if it runs yet though …

I have exactly the same Error.
I tried to reinstall VS 2017 and 2019. Tried to download from Github and set up an clean pre-buil setup. I tried to do this all as an Administrator (only my user accounf allready is an Admin on my Windows 8.1 mashine).
But nothing solved the problem.

I added like allready mentioned “Ref” to the coding line. Builds without problems, but it is unclear if the Change has any impact on the functionality of UE4 with Chaos.

Update1: Unreal Engine Editor doesnt start after Build (Build with added Ref).

Update2: Solved: Works for 4.23.1. Should look like this and it will build, start the engine and chaos works.

You should stick to 4.23 for now with Chaos.
It is impossible to use Chaos in 4.24 (assuming you managed to compile it) because the game will always crash when you have a geometry collection in your level.

I heard it’s still not working in 4.25. Look the last pages of this forum thread : https://forums.unrealengine.com/unre…o-enable-chaos
