player collision ?

Hi, My Player goes through wall , how can I fix it ??

How are you controlling your character?

put a collider on the walls and the character if you are translating your character

my character has a character controller and the walls is FBX I cheked the generate colliders
my controller is translating by the arrows keys

on the walls put a box colider

the problem is not in the map because the First Person Controller doesn’t go through , the problem is somewhere in my player . anyone has an idea how to fix it ?
