RVOController Radius affact self pathfinding

if the radiu is larger,for my game radius =1,then the player will move jigglely.
how to avoid this?
btw,when I set radius = 3, then the path look rather weird.

hero shake when move.
I‘ve tried disable collision detect with hero layer and set symmetryBreakingBias in simulator to 0.2.all is nothing except I change the radiu to be a small value ( 0.5 or lower)

It seem to relate to the Controller’s collider

to keep distance from other players,so I set agent to collision each other,while it affect move .
keeping distance is also necessary, so how to do with it

slow the rotate speed will be a little batter.
while it’s not the final solution in my opinion
