Limit Distance Constraint¶
The Limit Distance constraint forces its owner to stay either further from, nearer to, or exactly at a given distance from its target. In other words, the owner’s location is constrained either outside, inside, or at the surface of a sphere centered on its target.
When you specify a (new) target, the Distance value is automatically set to correspond to the distance between the owner and this target.
Important
Note that if you use such a constraint on a connected bone, it will have no effect, as it is the parent’s tip which controls the position of your owner bone’s root.
Options¶
Limit Distance panel.¶
- Target
Data ID used to select the constraint’s target, and is not functional (red state) when it has none. See common constraint properties for more information.
- Distance
This number field sets the limit distance, i.e. the radius of the constraining sphere.
- (Reset Distance)
Resets the Distance value,so that it corresponds to the actual distance between the owner and its target (i.e. the distance before this constraint is applied).
- Clamp Region
Defines how the owner is constrained relative to the spherical boundary, determined by the Distance setting and the target’s origin:
- Inside:
Restricts the owner to remain within the sphere.
- Outside:
Prevents the owner from entering the sphere.
- On Surface:
Constrains the owner to the sphere’s radius.
- Affect Transform
Transform operators will take the constraint into account to immediately restrict the resulting transform property values.
- Target/Owner
Standard conversion between spaces. See common constraint properties for more information.
- Influence
Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
Tip
Evaluating both owner and target in a Custom Space using the root bone or any other suitable parent bone will automatically scale the effective distance with the relevant part of the rig.
