Hi guys, thanks for clicking on the post 
As I think a video is better than words I made something to illustrate :
The player sometimes get immobilized on collision and then continue its course keeping its previous velocity
Its often when the car â– â– â– and nose touch a collision that it happen
So it seems that there is a correlation with the player rotation
I tried to rotate with “Add Controller Yaw Input” and by modifying the transform but both ways had this problem
Cant find anything when googling so I come here for help
I’m fresh new on Unreal so I might miss something…
