Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Deploy to Nexus 9, I get a red screen.

Deploy to Nexus 9, I get a red screen. This happens in 4.8 preview 3 and 2. In 4.7.6, Nexus 9 is crash after the black screen. And the home screen is displayed soon.

I can deployed in 4.7.6 (launcher version), and I can also play in the Nexus 9. With the DXT mode. Tegra K1 have a great performance compared to the other chip. But it will not get the reflection effect, because the Open GL ES3.1 is not available. So, download the 4.7.6 and 4.8 preview at Git, and has been working following order.

0; Using TADP (4.0r2). API (22) was also installed. (Nexus 9 System is 5.1.1)

1; Opened UE4.sln with VS2013 and build "Development Editor" "Win64".

2; Rewriting the BaseEngine.ini in source code.

bBuildForES2 = false

bBuildForES31 = true

3; Rebuild "Development" "Win64" and "Android". (not "build")I do not have an error.It is success.

4; Start the UW4 editor, and packaged in Android ES31 + AEP. (or launch the Nexus 9)

5; Editor message is "Launch Complete !!"


Result

I have same result, in the two PC. Win8.1 and Win7.

4.7.6; Black out and crash, or I get an error message.

4.8Preview 2,3; I get a red screen. When I deploy the FirstPerson (BP), I will play. But if tap the red screen I can hear the shooting sound of the gun. (Shooting the gun in my blood sea! bang! bang! Oh my god !!)

Question

1; Can really use the "Android ES31 + AEP" on the Nexus 9?

2; If can use the reflection effect, and other effects are supported effects such as PC?

3; I do not remember installed the "AEP". Is it OK? How do I if it is necessary?

4; Nexus 9 resolution (1536x2048), it is no problem?

5; ON a single computer ,"LogRenderTargetPool: Warning: r.RenderTargetPoolMin exceeded 439/400 MB (ok in editor, bad on fixed memory platform)" I get a lot of messages in the Log.Is it OK?

6; Please point out if I wrong my order.

log_4.8p3

I'm sorry, please forgive the double post. Because there was no answer reply. Please close the Japanese Section if I resolved.https://answers.unrealengine.com/questions/227253/

And English is also bad.

Thank you, UE4 team.

Hey Pafupafu,

Looking over the warnings on the screenshot provided, it looks as if you're having trouble with a specific blueprint widget. Please look over the blueprint for 'Widget3DPassThrough_Translucent' and 'Widget3DPassThrough_Translucent_OneSided'. I'd also suggest looking through any other errors that may be on that message that aren't showing up.

Also are you trying to launch the project from 4.8.3 source and 4.8.2 source or is 4.8.2 binary (from the Epic Games Launcher)? Are you able to package any other project/template from either version of the Engine? Is this only happening with one of your mobile devices or all of them?

Here are some links that may help you with the issue you're running into:

Looking forward to hearing back from you, thanks!

Hi Pafupafu,

The red screen issue on Nexus 9 is due to some driver differences between the Shield Tablet and Nexus 9. There are fixes for this in 4.9.

Hi, UE4 team, I wait for the next release. In 4.9,we'll need to compile the source?

btw,in 4.8.3,i can't compile with "Development" "Android". "Android" menu was not displayed. in 4.8.2 and 4.9.0(beta?), i couldn't similarly. in 4.8.1, i can compiled it.(Of course red screen.)

Thank you,

Yes, you will need to wait for 4.9 to release in order for this issue to be resolved. You may see it available in the 4.9 Preview 1 but I can't guarantee that at this time.

Since the issue is being resolved in 4.9, you will more than likely still see the issues occur in 4.8.3, since 4.9 is after 4.8.3. If you're having another issue, would you mind explaining this a bit further. Please make sure you provide the full version number with your next reply so I can pull the proper build that you're on.

Thanks!

Hey Pafu,

  • Which version of the engine were each of those games from?

  • Which version of Android is your Nexus 9 on?

  • Are you still using the 4.9 preview, or have you upgraded 4.9 to the release?

  • Do you have any logs you'd be able to provide for us?

Hey Pafu,

Could you please post this issue in a new thread, since it differs from what you were originally having trouble with? I have our Android Developers looking into this further.

Please comment back here once you've submitted the new post, so I can grab that one.

Thanks! :)

Actually, if you care to also start a thread on the artifacting you are seeing ,that would be good too. They appear to be 2 separate issues.

So, a new thread on the poor performance for Nexus 9 ES31.

And another new thread on the major artifacting (your psychadelic colors) for ES31. I was able to reproduce this one on a shield tablet, so it's not specific to the Nexus 9 hardware only. Otherwise these issues have been logged as bugs and are being tracked anyway. Thank you for this info!!
