Mesh collider not working

okay so I have my road collision set to mesh and put in the same model so it worked previously but now its just not working, why? I have rigidbody on static for the road and have my capsule set to dynamic ofc

Don’t know what’s happening I tried to reimport AMMO but nothing changes

here is the project: Museum | Editor (

In this project: Convention Centre | Editor ( I have the same size for the two objects and the mesh collides beautifully

How can I fix this?

Edit: Now both project are not working, I just added the terrain and now it’s not working…

What do you mean by ‘not working’?

For mesh colliders, I believe there is a restriction that the entity must be uniform scale. That means that the scale of X, Y and Z must be the same value.
