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"

Problem in using Vulkan. Packaging always avoids using Vulkan when making android builds.

I've been trying for a bit of time to package an android project for Android 'N' that would also use Vulkan. However everytime I package, despite my settings, UnrealBuildTool will not attach Vulkan to it.

I have enabled Vulkan in the experimental tab by adding "bSupportsVulkan=true" to DefaultEngine.ini in the project folder.

I have ticked the boxes for "Enable Metal/Vulkan/High-end mobile preview rendering level in editor" and "Allow Vulkan Mobile Preview".

I have the latest drivers for my graphics card, GTX 970. I have downloaded the android sdks using Nvidia Codeworks, and Android 'N' by using the sdk manager in the folder. I do have r12NDK, 1.7.0. JDK, Apache Ant 1.8.2.

I cannot launch UE4Editor with "-vulkan" as it leads to it crashing itself and the graphics card into recovery.

As a note, I do have build errors when I attempt build while having both tick boxes filled for armv7 and arm64 support.

Product Version: UE 4.12

Latest drivers = Vulkan specific drivers ?

Hey George,

Vulkan is only available via Source. The libraries are only included in Source. If you build the editor with the NDK or Vulkan drivers installed, you'll be able to package with Vulkan support for Android as well as run your project in Vulkan. You'd have to run it with '-game -vulkan' and that'll run with Vulkan via PC Preview.

You are not able to launch the Editor in Vulkan, it's not available at this time.

Thanks!
