Some physical attributes can be defined with the material
settings of Blender. The MaterialButtons can be accessed via the
icon in the header of the
ButtonsWindow or by pressing F5. Create a new
material or choose an existing one with the MenuButton in the
header.
In the MaterialButtons you need then to activate the "DYN" button to see the dynamic settings (See Figure 26-7).
This parameter controls the elasticity of collisions. A value of 1.0 will convert all the kinetic energy of the object to the opposite force. This object then has an ideal elasticity. This means that if the other object (i.e. the ground) also has a Restitute of 1.0 the object will keep bouncing forever.
This value controls the friction of the objects material. If the friction is low, your object will slide like on ice, with a high friction you get the effect of sticking in glue.
In conjunction with the "Do Fh" and/or "Rot Fh" (see Section 26.4) you make an object float above a surface.
"Fh Force" controls the force that keeps the object above the floor.
"Fh Dist" controls the size of the Fh area. When the object enters this area the Fh mechanism starts to work.
Controls the damping inside the Fh area. Values above 0.0 will damp the object movement inside the Fh area.
With this button activated the object also gets a force in the direction of the face normal on slopes. This will cause an object to slide down a slope (see the example: FhDemo.blend).
Specularity settings in the MaterialButtons
This slider controls the intensity of the specularity.
This slider controls the size of the specularity (hardness).
Activating this button, switches the RGB (or HSV) sliders to define the specularity color.
