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"

[Q] How do I use just the Nav Mesh for AI collision

There was once a Trello card for AI optimization that would only use the Nav Mesh for AI collision, not collision primitives.

Did this feature make it in? And if so, is there also a way of stripping out collision primitives during cook?

Using navmesh for collision (so called "Navmesh walking") is just a movement mode and it doesn't transparently plug into physics queries. What I mean is that we do support using navmesh as collision, but only for character movement. The feature will be part of 4.8 release.

Thank you. Will that then just become a Tick Box option on the Character?

And if we use this, is there an easy way of stripping collision meshes from data during cook?

"Navmesh walking" is just a movement mode, and you'll be able to pick it as character's default movement mode. Regarding stripping off collision during cook I suggest you created a separate question regarding this.
