How to enable Chaos

[wogdev]

I downloaded destruction demo from launcher.
whould you please tell me where can I find demo folder??
I looked for in vault chche folder, but there was nothing.
Do I have to make a project from launcher and use it?

It's in Documents/Unreal Projects by default i believe. So full the path is C:\Users\%YourWindowsUserName%\Documents\Unreal Projects\ChaosDestructionDemo

So chaos replaces the physx but is it on par with it in both cpu and gpu acceleration?

When production ready it should already be way better than PhysX performance wise.

My 4.22.2 behavior tree stopped working on migration to 4.23.1.

it currently insta-crashes the editor as of the current preview build.

I am trying 4.24P1. Chaos is there. When I create a GeoCollection from a simple cube and put into a level. It crashes. 4.23.1 works OK.

Chaos Destruction is planned to be built into the launcher engine by 4.25 (right after GDC 2020). Has anyone tried to build Chaos Destruction with 4.24 yet?

Epic Games updated UE4 roadmap pages, in the Future Releases section:

https://trello.com/b/TTAVI7Ny/ue4-roadmap

Chaos support on Mobile

Chaos Physics (production ready)

I would be surprised if that is going to happen anything later than 4.26 It seems pretty obvious that they need it for their own products and quickly adding support for Mobile too clearly hints at Fortnite as other developers suggested in this thread. Which is a good thing for all UE4 developers anyway. The APIs should quickly become rock-solid with bugs fixed at least that seems obvious. And I'd say along with Niagara and Virtual Texturing. These APIs got a development speed-up clearly for a reason.

Ok I finally got it compiled in VS19 using compiler 14.22.27905 and SDK 10.0.18362.0. Instead of building chaos demo's ue4 solution, I built UE4 SLN from GitHub source after rerunning setup and generate bat. Chaos clothes, solver etc enabled without trouble but haven't started using them yet.



The b compile chaos also needs to be in ue4.editor.target.ini like this,


Edit- Grr lighmass still needs to be built separately.

Probably a couple more versions, maybe 1-2 more years.

1-2 years until Chaos is out of beta? What?
Epic Games is releasing at least 3 Unreal Engine versions each year.
Virtual Texturing is going out of beta.
Chaos won't take another 1-2 years from now. That is quite unlikely.
Even because it has obviously been in internal alpha/beta stages and tests for a very long time already
before they unveiled it to the world with the 4.23 release. Or do you think that they started coding it just
a few months before the 4.23 release, perhaps?
Also Niagara and Chaos are tied and they are improving Niagara features with Chaos. So expecting
Chaos to remain in beta stage until 4.30 or later versions is just nonsense. Unless something really bad
happens code and project wise forcing Epic Games to delay Chaos I would expect it to be production
ready by 4.25 or 4.26. Probably after Chaos being production ready they will start unveiling the full PhysX
replacement for all physics related simulations and not just destruction. Chaos won't replace other PhysX
features and uses in UE4 but it seems obvious that it is just the beginning of a longer term plan to completely
replace PhysX.

is there an alternative to chaos like Blast, i mean is there a launcher version of Blast maybe that you know of ?

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

[porckchop]

When can we expect a UE4.23 launcher build to be released with chaos already integrated without the need of using a source build. Because using source limits you from using many Marketplace assets.

[lazysnake61]

So should I build chaos demo or UE4 in VS?
edit- It's also giving error about something called openvr path registry being not found.
