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"

Why won't my Nav Modifier cover my entire Nav Mesh?

I have a Nav Mesh setup that covers a large area and I tried to put a Nav Modifier over it but the Nav Modifier will not build outside a 2000x2000 square in the center of the level. I've even tried setting up 200x200 modifiers and putting them in a completely empty spot with no obstacles but they still won't build unless they're within the 2000x2000 square in the center. I took a screenshot of my problem, the modifier is the purple box and it's set to 7400x6000 but won't grow bigger than 2000x2000 and I can't place another modifier outside of that box, even if I delete the one already there.

Is this a bug with the engine? I've been trying to figure it out since yesterday.

Edit: I should note that if I delete the NavModifier and create an entirely new one it does build completely but when I reload the project is when it limits to the 2000x2000 box.alt text

I fixed this by manually dragging out the size of the Nav Modifier rather than typing in the size I want. This must be a bug with the engine itself.
