Tasks

Task General UI

Position Task

The following parameters specify the behavior of the position task

 

 
  • Active - select this to enable or disable the task (the constraint)
  • Retargeting - if using internal for IKINEMA Action retargeting setup, the task can be set to follow a trajectory defined by a source joint or a transform (see retargeting below), you can select whether to enable or disable the retargeting feature. For example at a given key you might decide to disable the retargeting and manually move the task/constraint to achieve the desired effect and customization in the scene and then key-frame this position.

Note: In Action 2.5, use Bind source joint to Point constraint instead

  • As Pole Object - Use this option to convert the task to a Pole Vector constraint for pointing knees/elbows or any bone
  • Scale/offset Retargeting X,Y,Z - during retargeting, these parameters allow adjusting the position of the task for the target in respect to the source. For example if you are retargeting to a target that has shorter legs in respect to the source, you might decide to adjust the scale along Y to move the target position task upwards to align with the target's bone length. Videos are included below to demonstrate this.
  • Solving Degrees of Freedom (dofX/Y/Z) - Set the desired degrees of freedom for the solving; By default all X,Y and Z are enabled. You can disable one to achieve bone moving along a line; two for a bone moving on a plane (sliding effects). When all three are set, the bone will maintain a point in space position.
  • Weight - increase this to achieve a better tracking of the target or reduce to allow some error
  • Precision - increase this to achieve a better tracking of the target or reduce to allow some error
  • Depth (-1 = task is non-active) - Set how far the solver needs to go for satisfying a task; for example only one bone backwards or to the root.
  • Priority (1st or 2nd) - a particular task can be set to low priority to give less emphasis on satisfying its position/orientation

 Orientation Task

The orientation task has simiar attributes as the Position task above.

 

Look at task

To create a look-at task, select a joint, then a destination object and select from IKINEMA menu, Create look-at task; This will define an orientation task with a look-at behaviour. This can be used on head, spine or any bone. You can specify an offset on top of the look-at direction using
