To open the Floor Contact attributes
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.
Activate Feet Floor Contact to prevent the feet of your model from going through the floor. The options within the Feet Floor Contact Setup folder let you adjust how feet make contact with the floor.
| Option | Behavior |
|---|---|
| Normal | Six markers define each hand's floor contact. The middle markers should define where the fingers begin. |
| Wrist | Four points define each hand's floor contact. The hand markers display around each palm. |
| FingerBase | Four points define each hand's floor contact. The hand floor contact markers display around each hand's fingers. |
| Hoof | Four points define each hand's floor contact, but the points are oriented at a 90 degree angle, letting you define the floor contact for animal types with hooves, such as horses. These contact markers allow for 180 degrees of movement. |
| Option | Behavior |
|---|---|
| Sticky | Each finger sticks to the floor exactly where contact is made. |
| Spread | Spreads the fingers as they make contact with the floor, attempting to keep the position of the fingers intact. Rotation is applied to the root of each finger. |
| Sticky & Spread | Averages the finger behavior between Sticky and Spread. |

Behavior |
|---|---|
| Auto | The default option that averages the priority between the wrist and fingers. When the hand makes contact with the floor, the wrist is translated backwards and the fingers are pushed forwards. |
| Wrist | Gives the wrist priority and defines it as a pivot point for the hand’s floor contact. When the fingers make contact with the floor, they are translated forward to keep the wrist’s trajectory towards the floor constant. |
| Fingers | Gives the fingers priority and uses them as the pivot point. When the fingers make contact with the floor, the wrist is translated backwards to keep the fingers firmly planted on the floor. |
Lets you define how stiff and sudden the hand becomes as soon as any part of the hand contacts the floor.
For example, using the default settings but only adjusting the Hands Contact Stiffness to 100%, as soon as the fingers of the hand come into contact with the floor, the hand stops translating. At 50%, the hand translates gradually after coming into contact with the floor.
