First person camera with 3D Max

Hi there,

for my next project i want to create a scenery you can walk through,
using the first person camera in max.

I´ve been looking at all the ducumantation i found so far…
And also the Floortest sample created with blender.

as far as i undestood it i only need to create a colision material.
This material should prevent the camera from going through walls etc.
and prevent the camera from leaving the predefined floor.
No physics etc needed….?

So far so good…..But it doesn´t work.
The camera goes through walls and leaves the ground.

Did i miss something essential?
