CHaracter walking through walls

I have several blender models and my player model keeps walking through the walls. For one type of platform I have three pieces - the floor, the right side wall, and the left side wall. For the second type of platform, those three pieces are just one model. In either case, when I check generate colliders the player will walk on the floor that’s placed horizontally but will walk through the vertical walls. How can I stop it from walking through the wall models?

Sorry for late reply, If you are using mesh collider, you need to tick convex under mesh collider component. You need to add rigidbody too.,

Or add simply characetrController, and edit his collider

@m0rr0ws0n I have same problem, the object through wall/object/cube. The problem solved after I reinstall the Unity software.
