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"

Navmesh needs to be rebuilt problem

Hi guys, I am having an issue with the Navmesh, it's perfectly fine until I change any of the settings in the recast nav mesh object and then it stops working completely, even after manually rebuilding the paths in the drop down a 'Navmesh needs to be rebuilt' error message pops up and none of my AI objects work at all.

I checked around thinking this is some kind of bug but apparently an issue like this was fixed in 4.8 so I wasn't sure if I was simply doing something wrong? The only way I can get things working is just using the navmesh as default but I need to be able to change the cell size for my level.

Thanks in advance. :)
