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"

Capsule Component Affecting Navigation

I am trying to have the capsule component on my character affect the navigation by checking "Can Affect Navigation" in collision. This works for the most part but the problem I am having that if I set my capsule's radius too close to the half height it stops applying the navarea I selected to the navigation.

Any ideas on why that is or how I can fix it? My current solution is to add a box collision and use that for the navarea but I'd rather not add a new component just for that reason.

I can verify that in 4.13.2 this is still an issue. A capsule component in which Half Height equals Radius is ignored as a navigation obstacle.

Hey RotemS,

I've attempted to reproduce your issue, but I'm not seeing the same results.

Here's what I did:

  • Created a new pawn

  • Added a capsule component

  • Ensured it was set to BlockAll collision and that CanEverAffectNavigation was set to true

  • Set the Capsule Half Height and Radius to 22

  • Placed the pawn in my level

With this, I still noticed it affecting the navigation as expected. Could you provide some screenshots of your setup, and also attempt to reproduce the issue in a clean project and provide me with the steps you've followed?

Hi Sean,

Thanks for looking into it. alt text

Steps are identical to yours.

Also added a navmesh bounds volume and set it to dynamic with modifiers.

After further testing, this issue appears to be resolved in 4.14 Preview 2. Give it a shot in that version and let me know if you still run into issues.

Have a great day!
