In the following procedure, you adjust how the character’s feet touch the floor
using the floor contact markers.
The floor contact markers are the blue and green markers that appear around
the character’s hands and feet when you characterize your character model.
These markers create an invisible grid that determines where the character’s
feet come in contact with the floor.
When no floor object is defined in the Mapping list of the Character Definition
pane, the MotionBuilder grid is used as the floor. In this tutorial, the floor is
not defined.
1 In the Character Controls window, make sure Floor Contact is active in
the Show menu (A).
The green and blue floor contact markers display around Mia’s hands
and feet.
2 In the Viewer window, click the View menu and select Ortographic >
Producer Right (or click Ctrl-R) to switch to Producer Right camera view.
3 Zoom in on Mia’s feet as shown in the following figure.
4 Click the Translate button in the Viewer toolbar (or press T) to activate
the Translate mode.
5 Select one of the floor contact markers underneath Mia’s feet and translate
it, using the following guidelines and figure for the marker placement:
■ Align the middle marker where the toe bone starts (B).
■ Align the front marker with the toe of the model (A).
■ Align the rear marker with the heel of the model (C).
NOTE Moving one foot marker adjusts the other markers accordingly so
that as you adjust the green markers on Mia’s left foot, the blue markers
on the right foot also get adjusted.

6 Switch to Producer Front view (Ctrl-F), zoom in on the feet (Ctrl-drag),
and translate the foot markers right or left to position them at the edges
of the feet as shown in the following figure.
7 In the Character Settings pane, expand Floor Contacts (A) and activate the
Feet Floor Contact option (B) to activate the floor contact for the feet.
