Hey ,
Okay, so VR Preview is broken for you, do you have any links to AnswerHub posts regarding this that you have previously posted?

[/]

Sure:

It’s not broken ‘for me’, this was a known issue, even in preview state for 4.8 and wasn’t fixed for the whole lifetime of this release.

In 4.9 there’s the next VR-bummer:

[4.9 P1] "isHeadmountedDisplayEnabled" always reporting TRUE - XR Development - Epic Developer Community Forums (Headset now isn’t even correctly detected anymore)

The reaction:

I do not have a timeframe of when it will be fixed, however it is unlikely it will make it into 4.9.

Great. Just great. Just release it this state, why not.

Another thing is the issue might actually not be Epic’s fault at all and could potentially be the graphics driver you currently have installed.

[/]

No, it’s not.

[=MC ;357477]

Hope everyone is having a great week and if I can help out in any way , let me know and I’d be glad to lend a hand. Take Care guys and have a great Monday!

You want to help me? That’s nice from you. Please tell Epic they should release weekly patches for their major versions instead of leave basic functionality broken for months which were internally fixed long ago, that’s all.

And yes, the staff is indeed awesome. They are very competent, friendly and often very, very helpful. I really appreciate that. But unfortuntely this doesn’t change anything about their release policy. That’s the reason why I had to switch to the Oculus branch and now having fun with compiling and packaging errors.

Many thanks.

Any news on **[FONT=Helvetica Neue]UE-19190 **[FONT=Helvetica Neue, Helvetica, Arial, sans-serif]? It’s kind of depressing that adding 100+ achievements makes your game crash on play sign-in.

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

**MainFrameActions: Packaging (Android (All)): UE4Editor-Cmd: [2015.08.19-11.15.23:259] 0]LogSavePackage:Warning: Finished SavePackage C:/Users//Documents/Unreal Projects/Balloony PoP Revised 4.9/Saved/Cooked/Android/Engine/Content/EditorMeshes/ColorCalibrator/SM_ColorCalibrator.uasset

**For a very long time compared to Preview3, it does complete build but it’s just something I observed.

Hi, i don’t konw wehere to ask my question. I would like to know if there is a possibility to install the launcher and all the content of unreal engine on another disc than C: ?? if not, could add this option.
Thanks regards.

There are strategies on the Wiki that can help here. Essentially you want to copy the files to the new location, then create your OSes version of a hard link to the new location. In Windows this is called a Junction Point. In OS X and Linux, these are hard links.

Like I said, there should be some further instructions on the Wiki.

In 4.9 I can’t change any variable for child blueprint directly (only in parent BP) while in 4.8.3 is possible without any problem.
Is it bug or intentional change ?

Hi

This is still under assessment, however it has been marked as high priority in our system.

Hi ,

I’m a bit confused. Do you mean you are trying to change an inherited variable? Are you trying to change the variable type or the value of the variable? If so how are you trying to alter them?

Hi, anyone knows why the ScenTexture:SceneColor doesn´t work in PostProcess Material Domain in 4.9 ? it worked fine in 4.8. How can we use the SceneTexture in 4.9 for postprocessing?

Thank you !:.

Hi,

I just raised a new bug that is in 4.9 : UE-20145
It’s about UHT not properly handling some Preprocessor that caused build failing.
Let’s says you set #if WITH_EDITOR around a exec function, you won’t be able to build it out of Editor Configuration (means no cook so no release).

Thanks to get some attention on this.

Hi ,

I was able to reproduce this and have entered a bug report, UE-20179, to be assessed by the development staff.

364

Please more HTML5 out of the box support :frowning:

365

The new ES2 movable point lights look promising. Unfortunately, there seems to be an issue with them in HTML5 builds. They work great in the ES2 preview mode in the editor, but when running in an actual browser they cause many shaders to fail to compile, which results in the scene looking completely black, or blank, or strangely corrupted. I’ve created a simple project that reproduces the issue in an HTML5 build on UE4.9 Preview 3:

.com/Quadtree/UE4HTML5PointLightIssue

Simply launch into HTML5 and you should see some geometry missing, with shader compiler errors in the log.

Thanks QuadTree, I’m looking into this now. I’ve entered ticket UE-20202.

Seeing the image in the blogpost (4.9 Preview 4 Released For Early Adopters - Unreal Engine) I am wondering if there is an update coming to the Shooter Game :wink: Any info?

It just illustrates UI depth layers that were mentioned in this post: Engine Features Preview 7/10/2015 - Announcements - Epic Developer Community Forums

Hey, can I ask what’s the status of UE-19350? (The one about the Web Browser @ Web browser ui widget doesn't run - Blueprint - Epic Developer Community Forums)

Thanks :slight_smile:

369

How would I set up a material for parallax mapping?

[=wardoctor1909;358564]
can you guys fix DX12 it’s still crashing and i want to work with it please
[/]

This will be an ongoing thing, dont expect a fix overnight. I have found that since Preview 1, where I couldn’t even start the editor in D3D12 to now, things have improved dramatically, I only get a couple of obscure crashes now, so there has definitely been a lot of improvement, but I suspect it’ll be a while longer before all issues are completely resolved.

In fact, if you are not already, it would be helpful for you to raise answerhub posts for each of your crashes, this is the way to get D3D12 usable quicker, which ultimately is what you want.

That would be a great idea, it’d be nice to see an updated version of the Shooter Game focusing more on Blueprints than C++.

The only issue I’ve had so far is I haven’t been able to do a complete build at all using the production settings with any of the 4.9 Preview builds, which I’ve had no problem with previous engine versions until now.

Hoping that the Unreal Engine 4.9 Preview 4 build works for this.
