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"

Can't save a levels nav mesh if using world composition?

I've recently run into a fairly serious issue. I've been trying to figure out how to use world composition to better make a larger world with some parts that can be only loaded in as needed, but I've hit a bit of snag.

Every time I try to save a level after having built its navigation mesh, it fails to save. It will show the saving progress bar and all like usual for the level but then once it disappears the level still has the little asterisk on it showing it hasn't saved, and if opened it wont have any nav mesh.

While testing with different stuff I found out that some levels would save, but then instantly clear their nav mesh and have to rebuild it. This happened with smaller nav meshes, while the larger ones would just seemingly fail to save but not disappear from the cached level I was looking at. I've been looking around a bunch but haven't found anyone actually mentioning this (though it does seem nav mesh issues with world comp are somewhat common) so I figured I'd mention it here so it can be looked at by somone who may know more than me, or possibly even solved should I just be missing something that isn't covered in the documentation (nav documentation is overall lacking, and seems completely missing when it comes to its use in world comp levels).

I looked around and tried various things like making the nav mesh in the persistant level or such, but nothing I've done has worked.

Hi, I encounter the same issue in 4.18.2. Whenever I press the save icon, it will rebuild the navmesh again and cause the level change to the unsaved state.

Sadly still no fix figured out. In the end I moved towards having dynamically generated nav meshes, but given the nature of my game and the performance hit is really isn't ideal and has kind of slowed development to a standstill.
