FPSController vs RigidBodyFPSController Height issues

Hi all

I have noticed in my current project that if I use the standard FPSController that has a default height of 1.8 that I can enter a building entrance that is 3.18 high.


If I use the RigidBodyFPSController, with a default height of 1.6 I am unable to enter the building.

The building was made in blender and I changed the ScaleFactor from 1 to .5, in order for it to be scaled properly in my game.

So I am confused as to what is going on with the differences between the two controllers.
BTW, when using the FPSController with the building scale to 0.5, it is really does't look properly scaled when I use the RigidBodyFPSController.

Thanks!
