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"

Could you provide some clarification on the issue:

  • What functionality is not working until the editor is restarted?

  • Can you reproduce this in a clean project?

  • If so, please provide a detailed list of repro steps.

Hello Sean! Yes, It is reproduced in a clean project. steps i follow:

-create a new project

-create a floor, just a simple box

-create a nav mesh bounds volume, and extend it.

-create a nav modifier volume, and from nav modifier volume's details panel create new nav area, and from its properties, set any draw color.

-place the nav modifier volume inside nav mesh bounds.

When completed, nav modifier wont effect the world or draw the color it is supposed to. Only solved by restarting the engine as far as i see. Using one of the Defaultly created nav areas however works fine
