Unreal Engine 4.9 Preview

[MuhammadMadi]

this is cool

[Roccinio]

What are Unreal Engine 4's system requirements?
Will support Windows 10 64-bit?

I've been using 4.9 with windows 10 preview for over a month now and it works like a charm! So i see no reason why 4.9 preview 1 wont work with official win 10.

I'm most excited for "Functions can now have Multiple Return Nodes" on your list!

That said, I hope you guys consider allowing interface functions to be marked as pure, or for interface input functions to mark parameters as passed by reference!

Where is the parameter for this https://trello.com/c/jxYdAb9F/518-fi...scene-done-4-9 ?
*The feature pack rolling is broken.

[John Alcatraz]

So, a few things I noticed in 4.9:

- Some materials stay gray. They compile correctly, but once applied on a mesh they just stay with the gray default material.
- The spawn Actor node now uses a different way to define collision, which breaks current behavior. I before mostly used "Spawn even if colliding true" but now all the nodes were updated to the default value of "Try to adjust location, don't spawn if still colliding". This needs to change since it breaks all the Spawn Actor nodes!
- After I open the project I get this:



Seems to have no impact in the game.

Tempo?

PREVIEW!

• Sound Quality Levels give sound designers the ability to manage audio memory usage and some performance
• Asynchronous Real-time Audio Decompression available on supported platforms
  

Does this mean we will be able to control the tempo in music tracks?

[Hevedy]

Will support visual studio 2015 ?

[Roccinio]

I just tried to bring my project from a weeks old github version of 4.9 to this preview and i get these:

The project could not be compiled. Would you like to open it in Visual Studio?

Will {4.9} support visual studio 2015 ?

VS2015 is not yet supported in UE 4.9 Preview. We expect experimental support via GitHub in the final 4.9.0 release. This will be fully supported in a future release (possibly 4.10).

Will {4.9} support Windows 10 64-bit?

UE 4.9 is expected to run on Windows 10, but has not been thoroughly tested. Please let us know if you encounter any unique issues.

I hope directx12 is gonna be integrated in the full release of 4.9

DX12 has some early integration in 4.9, but is very experimental at this stage. To enable it, you run the editor on Windows 10 with the -D3D12 parameter.

[indygoof]

Get Class Defaults node gives access to Blueprints' values without having to create an instance

YES YES YES YES YES YES FINALLY THANKS!



I know quite many were waiting for exactly that!

[WarpSpasm]

Still comes with TADP 2.08???

[Grogger]

I'm always hoping to see improvements in UMG or news on Sequencer, but beggars can't be choosers and all that :P

Still, a nice list of things to look forward to!

[hippowombat]

Any hope for POM expressions in 4.9?

[Lovecraft_K]

So, a few things I noticed in 4.9:

- Some materials stay gray. They compile correctly, but once applied on a mesh they just stay with the gray default material....

Hi John -

Can you be more specific as to what types of materials are exhibiting this behavior? A screenshot of the material setup would also be help to track down this issue for you.

Thank You -
