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"

Hello 6r0m,

Thanks for contacting Unreal Engine User Support.

I was able to reproduce the issue you described, and found an existing bug report related to this. The issue has not been resolved, but you can follow the status of this at the link below:


For the time being, you should be able to simply restart the engine after placing and sizing the Nav Modifier. Once you reload your project, just move the Nav Modifier slightly and it should draw correctly.

Please let us know if you have any further issues.

Thanks, Tyler

Hello 6r0m,

I have added 4.17 to the affected versions.

Currently, our development resources are dedicated elsewhere and UE-30174 is not a priority item. We don't have a timeframe for when this may be addressed. Please keep in mind that with source code access, a programmer on your project can implement your own solution, and you are welcome to share that result with Epic for possible integration.

Thanks, Tyler
