Mesh Collider didn't work unless i walk slowly towards it

Its weird. I created a wall example, and i have a collider mesh created (note that collider mesh is way off away from the original mesh therefore it should work fine) and, when i run the game, walking slowly towards the wall, it seems to work. But when my character run faster towards it, boomz, i fly through it.

Hmm. Mesh collider reaction slow? I wonder. Anybody have this issue before? Or is it me and my setting somewhere. Because it suppose to be straight forward. hmm.

if you’re using rigidbody make sure its uses continuous collision.
if you’re using transform.translate then dont use that use a rigidbody
