If your mesh collider is turned off initially then this error will happen.

If we're still getting warnings, it's not fixed, is it?

I also have error and the mesh works fine.
so I tried to ignore this warning by using #pragma warning disable but didn't work.
Expected results: there should be no error.

So make the error message go away again so we dont get spammed by it? I also have this error, the mesh works fine.

Resolution Note (fix version 2020.1):
Unfortunately, this mesh has too many smooth features, and the minimal convex hull of it will have more than 256 faces. In PhysX, a convex mesh can have up to 256 faces. Previous releases of Unity didn't print this error, but the problem was still there.
