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"

4.6 to 4.7 rendering issues on iOS

Hello! I've cloned my project into 4.7.3 and was able to run my game with minor changes in the blueprints. I had no issues with running on the devices. However, after I launched my game using 4.7.3, I had this problem which I do not know how to solve. Everything seems same as in 4.6. It is the landscape which has problems.alt text Can anybody help me with this? I have no issues on the PC.

Looks like this is a landscape correct? Looks the same as my problem on android I posted here: https://answers.unrealengine.com/questions/197606/landscape-chunks-black-with-47-on-mobile.html

Hello jedisongoku,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Could you tell me exactly what device you are seeing this issue on?

  2. Could you give me the exact iOS version that this device is using?

  3. Can you reproduce this in a clean project?

  4. If so, could you provide a detailed set of steps to reproduce this issue on our end?

hi Rudy, I'm trying it on iPhone 6 iOS 8.2.

All I do is to create landscape with 15x15 quads with my layered material and paint. If I do not paint, the main layer shows perfectly on my phone. Could that be the material I use? I tried many things but I still see the black chunks when i paint.

Hey, since we do not know when this issue will be solved, how can I ship my iOS game with 4.6 using github? I always get 64-bit binary error. This is the only issue I got with 4.6 and do not want to use 4.7 yet without landscape problem solved. Can you also help me with this?
