Synopsis

createMotionField

This command creates a force that pushes a fluid based on the motion of an object. One selects the objects that one wishes to push the fluid with and the fluids one wishes to affect. At least one fluid and one non-fluid must be selected. One will not see an effect until the object is animated. CreateMotionField creates a drag field for each object and sizes the volume boundary of the force to be a bit larger than the object. The drag field has inheritVelocity enabled, which causes it to drag relative to the movement of the field. Adjusting the scale and volume shape of the drag field can help to achieve the best effect. If one collides the fluid with the object,then it may be good to increase the drag field size, as the colliding voxels have all velocity damped out.
