    I download today 4.9p4 for using the editor with Dx12 & w10
    Added -D3D12 and when start the graphic controller crash and engine stop working (No response, minimize in windows bar)

    without -D3D12 start ok.

    With the latest AMD VR Driver
    AMD Catalystâ„¢ Display Driver version 15.20.1062.1005

    Nope, we use forward shading on mobile. Current tiled mobile GPUs are pretty bad at deferred shading because rendering to MRTs shrinks the tile size increasing the number of tiles you need to render and the GPUs tend to have limited bandwidth so DMAing the g-buffer back to main memory for shading is very expensive. We have some ideas on how we might be able to do efficient deferred shading on some of the higher end mobile devices but we probably won't explore that just yet. Instead we'll focus on improving our forward shading renderer for mobile.

    RE: MSAA, yeah MSAA + deferred is very expensive whereas temporal AA solves the problem much more elegantly in addition to solving shader + specular aliasing. Temporal AA is not without its faults but overall it's a great tradeoff IMO.

    The ticket that is in, UE-19818, is for the min roughness not working. Right now it's a something that is not considered when using static lights with the new Static Lights visible in Reflection Captures.

    I've added your interest to the ticket, but it is backlogged at the moment.

    I've just noticed there is a terrible grain with temporal AA on 4.9.

    you can reduce the star pattern by increasing the source radius of the static light.

    When they release it.

    But there is a 4.9 Stream today about Mobile. Who knows what else they will say/launch today/tomorrow for all to play with?

    I would like a working browser (widget crashes constantly for my in OSX) or something like JSONQuery integrated in the engine.

    I've lost track in the thread, is there any hope of trace interactions with UMG or more functional gamepad support in UMG? I feel like it wasn't mentioned again.

    I have compile issue even now.

    Error 4 error MSB3073: The command "..\..\Build\BatchFiles\Build.bat UE4Editor Win64 Development" exited with code -1. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.MakeFile.Targets 38 5 UE4

    Edit the"BaseEngine.ini",and compile"Development" "Win64" and "Development" "Android".
    I have lot of error.
    After applying the GitHub fix for ES3.1, building "Development Editor" "Win64" and "Development" "Android" works fine in 4.9 for me after changing bBuildForES31 to true in "BaseEngine.ini" [/Script/AndroidRuntimeSettings.AndroidRuntimeSettings] section. Creating an AnswerHub may be more productive to tracking down the problem at this point.

    I've also noticed that. It would be really nice if they could implement this little feature: https://forums.unrealengine.com/show...of-node-inputs
    Even without this bug it's hard to plug in wires when working fast.

    Anybody with strange error while pressing "Compile" from Editor?
    Just trying to compile a very basic c++ class which was perfectly working on 4.8, but doesn't on 4.9 due to this strange error:



    UE4.9 compiled from source (commit f5e5090 - tag 4.9.0-preview-4) on OSX 10.10.4 / XCode 6.4 + custom patch (removed "-fno-rtti" from MacToolChain.cs).

    Maybe that "???" in the path is preventing the linker to find the object file? How can i get rid of those question marks?
    Nevermind, sounds like the issue has been fixed after the 4.9.0-preview-4 tag.
    Cherry-picking commit a0e5767badb5ebb3d285633b1f45cc24ffebd8cc did the trick.

    Keep up the good work!

    Will this finally make my door able to rotate by pressing a key? It's been bugged for a while I'm pretty sure.
