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"

[IOS] Global Shader Cache File is missing?

Hey guys,

We're trying to get UE4 working on an iPad and we've got to the point where it will launch on it, but we get this error in the log:

 LogPlayLevel:Display: env: The global shader cache file '../../../Engine/GlobalShaderCache-
 GLSL_ES2_IOS.bin' is missing.

And on the iPad, the splash screen comes up, and then it's just black.

We've tried cooking the files, but it doesn't change anything.

Any ideas?

(We're just using the default First Person Code project)

Hi Ineni,

Some quick questions for you:

  1. Are you on Mac or Windows?

  2. Are you using the Binary or Source version?

  3. How are you launching the game (straight from xcode, from the editor)?

-Max B.

Alright Krudos, can you try these steps and see if you're able to launch successfully?

  1. Create a code project

  2. Compile the ProjectEditor-Mac in Development

  3. Launch the Editor

  4. Launch on Device

-Max B.

i know nothing about coding and i keep getting a pop up message about this game that was created in the unreal engine 4 about it missing a global shader cache file and i don't know how to resolve it. Could someone please give me a simple, watered down solution and not go into a technical explanation with words that i don't know. Thank you.

Please post your own thread to AnswerHub. This is a post from 2014 and it's outdated. Please include what version of the engine you're on, provide the exact error and whether or not it happens on every single project that you work on.

Thank you!
