Unreal Engine 4.9 Preview

[=MediaLocker;346306]
Im really passionate and glad that Epic have done such a great job with UE4. Unfortunately, I am forced to use other engines as the C++ documentation is lacking, and with every release ( and surprisingly often releases at that) the documentation becomes even more unreliable and out dated. You guys have added the pains of uscript scripting back into UE4 by not having a reliable source of documentation for C++ function and features.

Are the any plans to have a definitive and precise source of C++ documentation and functionality that isnt a rip from whatever project is working on at the time…? (thanks btw ).

Right now im begrudgingly resorting to Unity.

Unity has a different release schedule and doesn’t have source available. UE has major releases throughout the year and the source makes for excellent documentation. It takes longer to learn but is far more flexible, that’s the trade-off.

Right now, starting the engine with -D3D12 yields a much lower framerate on my project, bumping the rendering time from 8ms to 13ms. Not sure if that’s expected at this stage.

Interesting, Im not seeing the same decrease. Instead Ive gone from 5ms draw times to 2-3ms draw times using D3D12, the only issues Im running into is random crashing, but Ive put that down to early implementation for now.

I hope that the UE 4.9 Windows 10 fully supports:)

I was able to run UE4.9 preview 2 from the launcher on a fresh install of Windows 10, I didnt do much other than package a sample project as a android game but it worked

“Level Blueprints can now be communicated with via interfaces using the Get Streaming Level node” = I love you.

4.8 on Windows 10 is ridiculously unstable for me. Especially C++ Projects, for some reason.

I have a hard time reproducing them as well, as it occurs at random most times, but it generally happens during some blueprint-related operation. I’ll try to run the editor in debug mode next time, and see if I pick up something there.
I hope it Will become more stable With 4.9.

It is not possible to package a game when using the FJsonObjectConverter, as UE4-JsonUtilities.lib can’t be found. This problem also happens for 4.8.

Any news on the tiled landscape import problem where the whole world gets flipped on the Y axis?

This is fixed in 4.9

Multi GPU Support?

Is the common interface for VR motion controllers available in the preview 2? I see that it’s not in input’s plugins but maybe it’s elsewhere?

Volumetric fog/light shafts?

Thank you Mr. Ketchum and Mr.NickDarnell for answering my question.

So much whining for a PREVIEW release. It seems people doesn’t really know what a preview/beta release is. Just report your bugs/issues, that’s all. I’m running 4.9 for about a week and had ZERO problems, at least for what I need. Peace :wink:

Discussion about issues ≠ whining

Level Blueprints can now be communicated with via interfaces using the Get Streaming Level node

How can I implement this,could you please show a step-by-step guide on this?Thanks!

Is there documentation somewhere showing how the Vive Controllers are mapped to the Motion Controller values?

Few of the menu items flickers while hovering on Blueprints window.

UPDATE!

We have just released Preview 3 for 4.9! Please view the Known Issues List on page 1 of this thread for the updated list of known issues.

Known Issue UE-19780 - A browser window will pop up in addition to the UE4Editor application when running the Editor while signed into the Launcher. This will not occur when launching the Editor while signed out. Expecting a fix for this issue on Thurs (8/13) via a Launcher update.

Thank you for your continued help in testing the 4.9 build before its official release. As a reminder, the Preview builds are for testing only, and should not be used for the active development of your project.

Cheers!

wow… looks like you’re getting to the real grit issues… great work guys, i’ll bet you’re running around saying ‘so much to do, so little time’… well you’re down the rabbit hole now… enjoy

does this mean I have to re-dwnld the launcher now, or will it upgrade itself (i’m waiting for 4.9 B4 I start, I have the current launcher)
