dynamic navmesh update works nice by overriding UpdateNavigationRelevancy, i was able to use it with good results on my pc. Reducing the update frequency to 10 to reduce overhead (Project settings/Nav. System / Dirty areas update freq) gives jagged movement, so I don’t think reducing the frequency solves anything.
On the other hand, RVO avoidance still seems unstable/weird. Maybe it’s just a misconfiguration, but even when I select only 1 character to move to a desired location, sometimes it never really gets there, it just rotates around the destination point like it was slipping on a rotating ice around the target. I found it more acceptable if the characters just collide sometimes without RVO than using RVO. I still haven’t tried crowd simulation though
