Unity Engine
1

hi there i am using mesh collider some of my object but when i walk in my project with my fps character something goes wrong with my objects ;

If i use box collider or a bigger collider than my object it’s not happening. But i do not want to handle my all my objects colliders one by one is there any quick solution for it.
