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"

What is the official method to build lighting using level streaming

I tried to follow this methods:

https://answers.unrealengine.com/questions/210479/separate-lighting-between-streamed-levels.html https://forums.unrealengine.com/development-discussion/rendering/116128-building-lighting-on-streaming-levels-need-help

But there is a bug in which the level loses all its data. This a pretty critical bug. You can see the bug report here (and I encourage you to vote for it) https://issues.unrealengine.com/issue/UE-75254

So I wonder what's the official method to build lighting using level streaming since unhiding levels and building invalidates the data of all the hidden levels, and building the lighting of each level separately in their corresponding persistent level works, but it is automatically invalidated once you open the persistent level in which it is a sublevel
