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"

Did you ever figure this out? I'm having the same issue. I have a level made of procedural buildings that are made of procedural parts. There are tons of procedural things going on. I'm using level streaming to load and unload instances of my map over and over, but they're different every time, and obviously I want them to be consistent.

If you are using blueprints, check out the SaveGame system which will allow you to write data to a file:


If you are using C++, you could try something like this:


I either case you are just going to loop through the actors and write their transformations to a file. I am assuming you want to use them later to reload a procedural level.
