Gravity Property Editor

 
 
 

To create a gravity control object: Choose Get Force Gravity from the Simulate toolbar, Get Primitive Control Object Gravity from the other toolbars, or Create Force Gravity from the Hair toolbar.

To redisplay this property editor: Select the gravity object and press Enter.

The Gravity force simulates a gravitational pull on simulated objects, including in a negative direction.

Gravity is the most common type of "force" that you will use, for obvious reasons. Gravity is actually a constant that is the same for all objects regardless of their mass: every object falls at the same rate (remember Galileo and Newton?). However, everything changes at the moment there is air resistance/friction or when the object collides with another because that's where its mass, energy, and momentum play a major role.

For more information on forces in general, see Forces [ Simulation and Effects].

To use this force in an ICE tree, see Creating and Applying ICE Forces to ICE Simulations [ICE Guide].

Length of the arrow is determined by the Amplitude value.

Name

The name of the force.

Mute

Toggles on/off the force effect.

Strength

Amplitude

Sets the strength of the gravitational force in either a positive or negative direction. The default value of 98.1 simulates earth's gravity.

This default value is set as such to simulate objects properly when 1 Softimage units equals 10 cm. Depending on the scale of your scene, you may need to adjust this value to get objects falling as they should. For example, if you define 1 Softimage unit to be equal to 1 meter, you would need to set the gravity to 9.81.
