Generate Colliders not workign with Imported Maya

Hey fellas, so I tried making a simple box in maya and then imported using import asset into Unity. I checked the "Generate Colliders" box and put my FPS controller in but it falls right through when i test play it. In the FPS tutorial it was as simple as that but for some reason a basic box is giving me trouble.

Any ideas?

make sure your character controller is higher than your box. your distance from the ground depands to your world scale. you can change the character controller settings to achieve best results.

Same thing with 3ds max, the generate colliders box, Did you press Apply? I did and i just got mine to work.

I think its a random Unity bug i hope they fix it in a newer version :( cos you cannot add anything to the bootcamp demo ,the colliders refuse to work :( its a shame but I only really want the actual soldier for my own demo (if THAT works lol)
