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"

Landscape Chunks Black with 4.7 on Mobile

Running a project made with 4.7.3 (it also happened on 4.7.2, but not sure about earlier), I get entire landscape chunks showing as solid black while run directly on a mobile (android) device. If I have a single texture in my material setup and don't use layers it's perfectly fine. The moment I create my layer info then it occurs.

I posted the following forum post which contains some screenshots which help highlight the issue: https://forums.unrealengine.com/showthread.php?63373-Landscape-chunks-on-black-on-mobile

If I create a test project in 4.6.1 and create a landscape in the exact same manner it's perfect. As soon as I upgrade to 4.7 or create a new project the issue crops up. It happens every time you create a landscape with 4.7 and run on a mobile device so it can be easily re-produced.

I doubt it's something I have done incorrectly, since 4.6 I do the exact same process and it works. Looks like a bug with 4.7.

Hello Xenogenik,

I have a few questions for you that will help reproduce this issue on our end.

Quick questions:

  1. What Android device are you using?

  2. What version of the operating system are you using?

  3. Could you provide a detailed list of the steps that you are using to reproduce this issue?

  4. Does this occur when Launching to the device or after packaging?

Hi Rudy,

Thanks for following up.

I am running this on a Samsung Galaxy Note3 (SM-N9005), running Android 4.4.2.

I am developing currently on Windows 10 Tech Preview. I also tested UE version 4.6 on the same system which does not produce this issue. If it's strongly thought this is an issue I could with some effort setup a windows 7 or 8 build to test if it still happens on those platforms. I also use the binary distribution rather than compiled.

In order to re-produce this it's fairly simple, create a landscape with layered material and it occurs. I did write a massive detail of every step performed but then realized I had exceeded the character limit on comments by 900. Hopefully that's adequate, but that is all that it takes, create a landscape (does not matter the size, even a small one), create material with Landscape LayerBlend Nodes (I did also try LayerWeight Node and same thing), create the layer info for each layer and paint. It happens every time.

It also occurs regardless if I launch on device or packaging.

Let me know if more detail is required.

Hello kodmistrz,

I went ahead and double checked on this issue for you. This has been fixed on our latest internal build and the solution will be available in a later release of the engine. I hope that this information helps.
