    Are physics asset setups built in previous versions of Unreal Engine expected to just work with Chaos now that PhysX is deprecated?

    All of my vehicle setups are broken in 4.26. I even pulled down some assets from the marketplace that were broken, and the vehicle sample project is broken. I cannot seem to get vehicles to function.

            Enabling HZBO causes the 4.26 Preview 2 to crash:

            Code:

              In OP it says
              • Volumetric Clouds. The new Volumetric Clouds Actor provides a material-driven real-time cloud rendering system. The component requires a material to work. You can use the default one found in Engine/EngineSky/VolumetricClouds/M_SimpleVolumetricCloud.
              But there is no folder called EngineSky in my Unreal 4.26 installation folder?

              stupid me. It's in the standard engine content that you can enable inside each project.

                    If you're using PhysX Vehicles, that plugin becomes deprecated.

                    I guess, you will need rework your vehicles into Chaos Vehicles. I expect this is special area that might implemented very differently from the old PhysX version.

                        Can we please have build in 3D navigation system for Flying ?
                        I'm working on a space game that have aerial combat but the engine only have ground Nav mesh. The only plugin alternative we have is abandoned by the developer.

                        The Engine need this please!

                          Even after 2.5 years, poor rect light still doesn't have it's own icon.

                            Sooo... where is the launcher for Linux ?! Unreal Engine is amazing, but what's the point of releasing it on Linux, if I can't add any assets to my projects? And all courses and learning materials constatly refer to the Launcher.

                              Cloth crashes the editor when it collides with the environment if 'Collide with Environment' is enabled.
