There are two components involved in creating a character that respects the boundaries of a defined floor. First, there are floor contact markers and finger and toe tips that define what parts of a character’s hands, feet, fingers, and toes interact with a floor. Second, there is an object assigned to the character that represents the level and orientation of the floor.

Once you have activated and defined the floor contact for the character’s hands and feet, you can customize the actual floor those markers come in contact with. If you do not define a floor, the character’s hands and feet treat the plane at 0 on the Y-axis as the floor.
