    Everyone knows development takes time. Ever user already knows this.

    Some mentions are as follows-
    1) Leo Rakes posted that there are degradations in raytracing feature set and raytracing-UI functionality since 4.22.3
    2) Lesuge described experience where capital was invested, as hardware was purchased, for raytracing goal.
    3) I myself mentioned that I know another developer of an outside rendering engine who could potentially assist with opaque shadow issue Unreal development is struggling with.

    So you could imagine 2 approaches:
    1) address so that 4.23 isn’t released in a degraded raytracing-capacity; or
    2) postpone development based on a ‘beta’ designation

    How do you feel, which approach sounds better to you?
    1) degradation and new issues happen and it is expected to happen, will they be fixed? yes. Soon? it depends, crashes are important to fix, final visual might take more time.
    2) there were no promises on a release date for a fully complete feature, one should not take for granted something not available yet
    3) they are not struggling, it is something built from scratch to play along with the traditional method (raster) in a multitude of scenarios and play with another new feature: Niagara, also in Beta

    The only thing I can imagine is: wait for final release (out of beta) and better they dealing with this complexity than me!

      Feature degradation is not unusual as situations can be very complex as there are so many computer specifications around the world that use UE4. Stability is preferred, and I would say the degradation is not permanent - it will be addressed by stages when new versions come out.

        Any documentation or guidance available for Data Prep usage?
        The dedicated data prep graph appears to be different to the current Datasmith documentation.

          We've also added support for switching to newer C++ standard versions. To change the version of the C++ standard that your project supports, set the CppStandard property to one of the following values from your .target.cs file.
          C++14 CppStandardVersion.Cpp14
          C++17 CppStandardVersion.Cpp17
          Latest CppStandardVersion.Latest
          At the same time, we've deprecated support for Visual Studio 2015. If you want to force your project to compile with the Visual Studio 2015 compiler, you can set WindowsPlatform.Compiler = WindowsCompiler.VisualStudio2015 from your project's .target.cs file. Note that the version of the engine downloaded from the Epic Games Launcher does not support Visual Studio 2015, and we no longer test it internally.

          Visual Studio 2015 support was deprecated in 4.22, btw.

          You can force your project to compile with 2015 by setting "WindowsPlatform.Compiler=WindowsCompiler.VisualStudio2015" in your project's Target.cs file. VS2015 is no longer tested internally, though, so if you run into issues keep in mind that it's not something we support.
          Where can I find this Target.cs file? Is it related to any Visual C++ versions only? How is it also related to Unreal Engine 4.22.3 preview 4(game engine/level editor can't run properly)(now I have no error code 0x000007b via Epic Games Launcher)however this error message is popping up everytime I want to run UE4Editor.exe via file explorer. Is it because my PC(it's six years old) is too old?
          I have Windows 8.1 64-bit,8 GB RAM,AMD Ryzen 5 2600 Six Core processor 3.40 GHz,Nvidia GeForce GTX 1050 Ti.

            I have a really weird issue with 4.23 Preview 4 and Visual Studio.

            A few lines into the Cpp file, VS stops referencing the headers, no intellisense etc. Not sure how i should explain it otherwise.
            Attached are two screenshots, that make it a bit more clear. You see that there is no syntax highlighting of references in the code.

            This does not happen with every file, just a few of them across several projects. Mostly files that contain big functions.
            When switching the engine version back to UE 4.22, everything works as expected.

            The only thing that happend between the screenshots was the switch between UE 4.23 and 4.22.
            Sometimes a few more functions find their declarations, sometimes when just deleting a code comment!

            -Compiling works without any errors or warnings.
            -I tried deleting vs and intermediate folders and re-generating project files multiple times.
            -VS is updated to the latest version
            -I tried re-installing UE 4.23 preview and Visual Studio.


            I have not used a GitHub source build in a while, so i cannot exactly pin down the commit where this started to happen.
            This never occurred in any other engine version before.


            EDIT: I tested it with the ShooterGame example and updated it to UE 4.23 , the result is the same with larger files like ShooterGameInstance.cpp .

              It means whenever you want to compile the engine from source, you need to update Visual Studio to 2017, since 2015 is not guaranteed anymore to work and it is not tested by Epic Games during development anymore. You can opt install Visual Studio 2019.

              When you compile the engine, you must launch the editor from the installation folder used during the compilation process which is the one the binaries will be installed. These binaries won't be launched by Epic launcher as default.

              Your PC is fine!

              If you are not used to compile the engine from source, it is really intended for advanced users, so you can wait for the UE4.23 release that all this trouble won't be necessary. Chaos is very early preview, so if you are not used to handle bugs, during compilation or during run-time, I do recommend patience for the final release where things will be more stable and compiling the engine from source not be necessary to test Chaos (I hope).

                Well thank you for a respond. Also there's one typo. It should be "your" instead of "you".

                Comment


                  Sequencer Curves window suggestions/issues:
                  1. Is it possible to keep focus on currently selected curve-track after Undo operation without additional Pin curve action before that?
                  2. There is visual corruption in curve segment drawing after keys with Constant Interpolation (vertical parts of segment). I attached an image below.

                    Hi Nilson! You bring up some interesting thoughts.
                    1) In your experience, do you see that expected degradation winds up being a common pattern with the Unreal releases, like Chaos will work good in 4.23, but then we can expect to see it degraded in 4.24? ( Kind of how we saw raytracing released in 4.22 and then looking to be degraded in 4.23)
                    2) if no promises are given and we shouldn’t take for granted the availability of functional raytracing, users then really should optimally just focus on testing and reporting on Chaos for the 4.23 previews, right? (As opposed to over-complicating developers with raytracing reports that are not really ready to be addressed yet)
                    3) in your experience, do you feel that the built-from-scratch approach puts them in a predicament where any previously identified traditional solutions won’t work, meaning a fix for opaque shadows will be even more difficult?

                    Thanks, as always appreciate your thoughts and insight

                      Whoaa... I need to perfect my english to not be misunderstood I guess.

                      1) in general, degradation is not expected, but might happen in any development. For the subjects Raytracing and Chaos, we all saw things working good enough for us to believe that what we saw is what we will get sometime in the future, there is no way to fake things live at stage in shows. Developers are humans and can make mistakes, so while in "preview state", you will see plenty of them, which are all usually handled fast enough before the "release state". See, development is like an assembly montage in a car assembly company, so it might happen that there is something wrong at the shop floor which makes 1 in each 1000 cars to have a certain defect. Once you figure that an issue exists, you will study a way to fix that, but you won't stop the factory or the loss economically speaking would be too high. It would be completely different if the ratio was 100 in 1000 cars. I used this example, because there is a plan on releasing features along the way, and there is also a plan to fix urgent bugs immediately and performance degradation is something important to fix, but not as urgent as a crash. There are issues that will be promptly handled because they will prevent the use of engine in development, while performance degradation is still an issue, it won't prevent the use of engine, and by the time someone using these new features are ready to launch a game commercially, the issue would be probably gone already, since were are not talking about short period developments here for any project using the engine. Things we see in a show like GDC are planned, built and delivered within 1 to 1.5 years in advance.

                      2) 4.23 is not just about Chaos. There are several other things under development in 4.23: Niagara, Virtual Texturing, Realtime Raytracing, Cinema4d, VisualStudio2019, and this is only what we are having access. They got teams working on features we are not aware of too, but likely to see in a show (maybe?). All things are here to be tested. I know I test all my projects against any new release to see if there is something is broken or not, and usually they are not broken.

                      3) it is built from scratch because there was no previous work on this, we are talking about a new way of doing this realtime. There were no cards with the capability or powerful enough before. Every company which has their own engine, had to start replacing things in a non-optimized way just to have something working. We saw this happening with the few games which support realtime raytracing and they are few because again, this is something that takes time to accomplish. Optimizations came after. This is not how UE4 works because it is targeted to several platforms. A fix for opaque shadows is as simple if only thinking in the new raytracing method, but as it to co-exist with the traditional rasterized method, there should be something we poor mortals can't foresee. Remember that the engine produces output to work not only in Windows, but also Mac, Linux, PS, XBOX, Switch, and while those platforms don't have yet raytracing, any changes made in the rendering module should still work for those. Now, if you know someone which has deep knowledge in the old and the new rendering module and knows 100% of the new DXR API, please do recommend him to Epic, there is always a place for an expert.

                            Urgent heads up!

                            I have packaged a game, which was all OK while in editor, and all looked fine with a successful build in the end, but when running the packaged game, the simple landscape present was completely missing material (checkerboard only). While I dig some more, could anyone else confirm this? When and if I find some clue I will fill out a bug submission form, until there more insights are really appreciated!

                            PS: Used for test also, a package from marketplace with terrain and automaterial applied and it worked somehow. Still digging more...
                            PS.1: It turns out packaged will only work if you do a proper landscape material with layers, but if you apply a simple material (without layers) directly to the landscape it will show in editor, but not in a packaged game. I tested with raytracing ON and OFF, and the virtual texturing ON and OFF, the only new things which could be messing with it and in all situations the result was the same. Making a report with a demo project and repro steps.

                              RE: Chaos Physics

                              Will it support the Magnus Effect natively? It is sorely needed to properly simulate how spin forces affect the curvature and trajectory of a ball in flight (golf, tennis, soccer, baseball, etc). Here's a quick YouTube video fully explaining the Magnus Effect with included video samples. Or just Google for "magnus effect on ball" and you will get pages of examples videos.

                              https://www.youtube.com/watch?v=23f1jvGUWJs

                              This would be a real game breaker for many developers and you can find many posts related to the subject on this forum. Since PhysX does not support this at all, then only workaround has been to mock up force effects but the results I've tried and seen are always less than stellar.

                              Thanks!
