Constraints let you constrain the position, orientation, or scale of one actor to other actors.

Point constraint  causes an actor to move to and follow the position of an actor,

or the average position of several actors.

Orient constraint matches the orientation of one actor to one or more other actors.

Scale constraint matches the scaling of one actor to one or more other actors.

Parent constraint lets you to relate the position and rotation of one actor to another, so that they behave as if part of a parent-child relationship that has multiple target parents.

Aim constraint constrains an actor’s orientation so that the actor aims at other actors.

Main concept of working with animation constraints:

  1. Select targets and last select actor to apply constraint to. Constraint actor will be attached to the actor, that this constraint was applied to.
  2. Use W1/2.. properties in constraint actor details to specify weight for each target. Right now you can not use more than 5 targets, but there will be no limitations in future.
  3. Offset vector sets offset from resulting position.
  4. Rest Position property is used to specify position of actor when all weights are set to 0.
