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"

Manual rebuild of navmesh

is there a way to rebuild navmesh manually by registering components manually. I believe there must be , I"m curious what are the exact functions that is in charge of this?

My guess is : void UNavigationSystemV1::OnActorRegistered(AActor* Actor) void UNavigationSystemV1::OnComponentUnregistered(UActorComponent* Comp)

What I'm trying to do is to lock it so they dont' get rebuild by using bInitialBuildingLocked

however they don't seems to work.

If there's anyone who can assist would be great

Actually we're having an issue that navmesh insist on rebuilding every entire world though 99.99 of the data is valid. Asked on answerhub a long time ago , but gave up on getting any response :

Product Version: UE 4.19
