Any suggestions on how we can specifically test the DX12 features in UE4 4.9?
Wow… how do I go about fixing these?
Also, this project does NOT build at all. I can’t package it.

Trying to see if the new Android Works stuff works with debugging since previous versions just don’t work for me, not a great start 
EDIT: Also, wow this page really slows my browser down for some reason…
EDIT #2: Now going to try building for Visual . Getting a huge list of deprecated warnings and also getting some VERY odd errors about variable declaration being done more than once (even though it definitely isn’t!)
So Packaging seems to be broken completely for me. I can deploy in Visual to Android using the new (THANKYOU) NSight Tegra Debugger, but in editor I get a failed log. I suspect this is due to the list of Deprecation Warnings, and possibly the fact that the clang compiler now seems to run with -WShadow. I can see why, but I think that should really be an option you can turn off somewhere, because it’s perfectly acceptable to have those kinds of variables normally right?
Additionally, any game I deploy to Android currently crashes in GenericPlatformMemory.cpp - Line 77. This is with any game, even a default Unreal Project.
Edit: Packing in Editor for Android is completely broken. Created a new Flying C++ Template and tried to build for Android (DXT) - instantly fails.
Hi ,
The Program.Main: ERROR: Exception in mscorlib: Illegal characters in path. issue looks to be a problem with the new code to break out the PATH environment variable to try locating xgConsole.exe.
You can work around this for now by changing XGEConsoleExe in Engine/Source/Programs/AutomationTool/UE4Build.cs back to:
public string XGEConsoleExe()
{
return @"C:\Program Files (x86)\Xoreax\IncrediBuild\xgConsole.exe";
}
I’d like to see your PATH variable contents to see why it doesn’t work for you.

Hey - I can grab those tomorrow for you, where do I find them exactly?
I know that I was also having trouble with Environment Variables when it came to using TADP… Also I thought you may wanna know, I installed the new AndroidWorks system that came with 4.9 - didn’t work with 4.9 of course because of the above problem, but went back to the 4.8 version of my project and the debugger instantly worked. It’s like a transformation…
There are a few issues though. If the engine hits a Breakpoint or a ‘check’, VS doesn’t take you to that location in code, the debugger just stops. You have to check LogCat to figure out where the crash was which unfortunately means you don’t get a callstack to debug the issue further. I did however manage to at least fix the game insta-crashing in 4.8, turns out we had some NAN vectors being generated from our Orbit generator. Took three days but got there eventually 
It seems as if the PC / Windows .exe can gracefully handle NAN’s when they’re generated, but the Clang-compiled version doesn’t like them at all…
Is the debugger meant to just exit like that, or should you hit checks / breakpoints in Unreal as well? This is 4.8 of course, so I imagine that version isn’t fully integrated with Android Works yet…

Hi Bladerskb -
Can you let me know exact what type of material (material attributes) which you are copying from and pasting into? Also are you using a project that has been converted from 4.8.X or a fresh project from 4.9? As much information as you can give me for a reproduction would be helpful.
Thank You -

Small bug in preview 4: When adding a TextRender component to a blueprint actor and changing its text value, it won’t update the change in the blueprint viewport until you save and close the blueprint, then re-open it.
Not sure if it is intended but if I edit axis or action mappings and have some groups closed and I add a new mapping to an opened group, several other groups open up themselves.
This can be quite annoying if you have many groups with multiple mappings…
EDIT: Another bug:
The array get input pin is hard to plug in:
Was the issue of red screen of Nexus 9 solved in this Preview 4?
I can’t build with VS2013.

Hi Mosel3y,
I was able to reproduce this and have entered a bug report, UE-20355, to be assessed by the development staff.

Also when packing a game for android the packing seems to hang on:

Hey
Have you submitted an AnswerHub for this issue you’re having with Android? If not, could you please create one and provide us with a full .txt file of the error?
Thanks!
Anybody with strange error while pressing “Compile” from Editor?

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?

The red screen on Nexus 9 issue was fixed for 4.9 but a compile issue was introduced for OpenGL ES 3.1 when MSAA support was added. Here is the commit to fix it:

Personally I dont think so. AFAIK MSAA with deferred shading doesn’t work well(bad performance?). Though I’m not a rendering dude so I might be wrong…
“Level Blueprints can now be communicated with via interfaces using the Get Streaming Level node”
How can I implement these?Thanks!
