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"

Smallest possible package on Mac?

I've read up on https://docs.unrealengine.com/latest/INT/Platforms/Android/ReducingAPKSize/index.html and various posts on answerhub/forum/reddit and am doing these steps for packaging a blank C++ shipping build:

  1. Generate a blank C++ project.

  2. Create an EmptyMap

  3. Project Settings->Maps & Modes: replace all Default Maps with EmptyMap

  4. Packaging Settings->BuildConfiguration = Shipping

  5. Packaging Settings->Pak File, Create Compressed Package and Exclude Editor Content checkboxes = on

  6. Packaging Settings->Include Prerequisites = off

  7. Packaging Settings->Full Rebuild = on

  8. Packaging Settings->Include Debug Files = off

  9. Packing Settings->List of maps to include in a packaged build: only EmptyMap (just in case)

  10. Disable all plugins

  11. Put PakBlacklist-Shipping.txt to project_root/Build/Mac. I set it to just one line "../../../Engine/Content/" to exclude all Engine content and see what that would result in.

I package by running UEditor->File->Package Project->Mac. Packaging after step 1 results in 263 MB, after step 10 in 204.5 MB and after step 11 in 172 MB (but the app crashes). This all is still way too much for an empty package with no content and no prerequisites. I saw a similar post about a Windows build and the guy was able to get it down to 90 MB ad was asking about driving it down to 20 MB.

I'd like to begin a new project with the smallest and cleanest start possible. What's the smallest package size for Mac?

Product Version: UE 4.15
