    I need some help also with using the fps template. I am using the shooter from the demo. https://www.youtube.com/watch?v=lr8qjOZToA4
    How about some new tutorials? Oakman.

    Did you build lightmass? Find it under Programs, right click and hit "Build", then try again!

    Yes, you should create a project and use that one.

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

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

    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.

    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.
