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"

Behavior Tree + Dynamic NavMesh slow down performance

Hi.

I have an AI with BT and navigation invoker, huge open world (NavMesh 'Runtime Generation': 'Dynamic'). AI is very primitive: move to near random location, wait 5 sec, repeat.

When AI is moving - FPS falls down from 80 to 20, but when stays and waits - raises to 80. Also, when I switch 'Runtime Generation' to 'Static' - FPS is stable at 80.

Could you tell me, please, what is wrong and how best to implement AI navigation in a huge world (4x4km, and even more).

Product Version: UE 4.21
