    When raytracing activated, the engine crashes when I hit play or simulate.
    In the github dev-rendering version of the engine this didn't happened.
    Hope you guys can fix it, thanks and keep the amazing work!

      Incredible update!! Time to invest in an RTX card I think, the possibilities with UE4 quickly becoming an all around visual media powerhouse are endless!

        Of all the fixes and improvements, I'm mostly looking for the one that would allow me to work with blueprints normally again:

        It's been almost a year since blueprints are nearly impossible to debug

            I can confirm this. It instantly crashes.

            Also, will my GTX 1060 run Ray Tracing or Is It exclusive for 20XX series only?

              There are a couple things I have sent crash-reports already for each occurrence, but I have figure some workaround for insta-crashes.

              - if you could create or open a project but crashes on hit Play: disable Magic Leap plugins to Fix.
              - if you tried to open a blueprint only project and it crashes before editor opens: delete Build and Intermediate folders and try open again. For C++ projects you need to right-click the .uproject file and select Generate Visual Studio Files before trying to open the project

                This is a biggie, kinda can't actually test anything useful by default with a new project since this is enabled by default...

                CREATING A NEW PROJECT WILL ENABLE THE MAGIC LEAP PLUGIN AND THIS WILL CRASH YOUR PROJECT WHEN YOU HIT PLAY.

                    Make sure to add inside the .uproject file these statements so the new project can be opened:

                    ...

                    , "Plugins": [
                    {
                    "Name": "MagicLeapMedia",
                    "Enabled": false,
                    "SupportedTargetPlatforms": [
                    "Lumin"
                    ]
                    },
                    {
                    "Name": "MagicLeap",
                    "Enabled": false,
                    "SupportedTargetPlatforms": [
                    "Lumin"
                    ]
                    }
                    ]
                    ...

                      This has already been confirmed to not work, only new Nvidia RTX cards are able (and any other card that vendor changes the driver to support this, depend on them not Epic's) and there is no fallback to old generations. See Epic's staff comment on this post: https://forums.unrealengine.com/deve...31#post1580431

                        hey VictorLerp ive bug-reported multiple times that cascade is somewhat messy in 4.19 and up, and its still not fixed in 4.22 (preview)

                        Could you nudge someone please? While niagara is getting much love, cascade is becoming a neglected child, and while that is somewhat okay.. it would be nice that before its depreciated its at least depreciated in a state where I can use it for clients who are far into production and do not consider adding niagara vfx content.

                        here is the issue:


                        thanks in advance

                              For those looking to get started with Ray Tracing. Here is what you need to do to enable it and use it:
                              • You'll need to be on Windows 10 Build 1809 with an RTX-20XX series card and the latest drivers.
                              • Use the command line argument -dx12 with UE4Editor.exe (for example, creating a shortcut and adding the arg at the end of the file path in the properties)
                              • In the Project Settings, the following in this order:
                                • Support Compute Skincache
                                • Ray Tracing
                              • Restart the Editor

                              From this point, you should have ray tracing enabled for your project.

                              You'll find a bunch of commands under r.RayTracing.* for different techniques. Some of which are disabled by default (like translucency and RTGI since they are still actively being worked on).

                              To use the Reference Path Tracer, use the level viewport and select Show > Ray Tracing > Path Tracing. You can find some cvars for it under r.PathTracing.*
