probuilder and collisions

I was learning probuilder, everything was going well until I tried to test it, I put a character in the scenario I created he was able to go through the walls so I tried several things to solve the problem, first I put a mesh collider but it didn't work , then I tried to put a box collider but it didn't work either, so I put several box colliders and to be all well put I used the edit collider option of the box collider, but in the end nothing worked, if anyone knows how to solve this problem it would be great help if you can help me

 

Thats odd, I'm putting a sphere with a rigid body on top of pro builder's newly built shapes and there is collision. Pro builder stairs come without a mesh collider, so you have to add that yourself.

 

yes i know , i always put the mesh collider but still the character goes through the wall

 

What I'm saying is it sounds like its your character issue and not pro-builder.
