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"

How are pre-computed visibility volumes are processed by UE4?

Just been digging in the source code a little for UE4 in the areas surrounding pre-computed visibility volumes. From what I can see in the source files, the volumes themselves simply inherit from the actor volume. I can't seem to find anywhere (anywhere obvious to me anyway, although I'm definitely not the best code digger around) in the code where the pre-computed visibility is actually calculated/processed. Would anyone know where I should be looking for information on the code behind the actual workings of these volumes?

This came about because I wanted to inherit from the pre-computed visibility override volume to cull all objects excluding a specific set of actors that I would select. Of course if there is an inbuilt way of doing this I'd be happy to hear that too.. When I inherited from the volume, I found that there wasn't much I could do in terms of changing any functionality or making any functionality of my own.

Thanks for your time
