NPC Navigation appears a lot worse than before

Summary

After some of the latest updates, the NPC spawner navigation became much worse.

There are some basic stairs that the NPCs used to climb with no issues and recently they get stuck while the player is able to climb normally. Also, they are pretty dumb and is basically impossible to handle the NPC navigation in a map with a lot of obstacles (even with Follow Agent function - they are not able to walk around even small objects like rocks)

Hi @Clebito! Thank you for reporting. Could you please either post or DM me a link to a video of this happening and the steps leading up to it? We’re having trouble getting a repro. Thank you!

And if you could add one with navmesh debug on this would be awesome!

Thanks!

I sent you the video via DM on the discord, hopefully that’s useful for the team!


@FrozenInMTL_Epic
debug + navigation was active during all the tests in the video. Thanks for the quick answer

Hi Clebito!

Can you check to see if you have “Can Ever Affect Nav Mesh” on the mesh component of your props? In the video you sent Flak, the fences (and other props in this video) are not affecting the navmesh. So the AI thinks there is a path but get blocked by the prop collision.

Hey there! Checking the “Can Ever Affect Nav Mesh” on the mesh component of the props really helped with the issue. Thanks!
