Now I use UE 5.0.3 version to simulate crowd avoidance(about 500 pawns).
I find some bugs in RVO and DetourCrowd :
(1) RVO : Out of NavMesh, pawns will be stuck and can’t move to destination any more.
(2) DetourCrowd : Avoidance ability is very bad, especially when the number of pawns is increasing, all pawns can’t avoid each other and stuck together.
(I have adjusted max avoided agents to 1000)
Both methods I have tried, now seems the effect of RVO is better, but the bug also exists.
I have investigated many articles and found these bugs have existed in UE version 4.
Whether anyone has a idea how to solve or what versions will improve these bugs?
