Constraints#

Clarisse offers a set of basics constraints that can be used to create basic rigs. Constraints operate on scene items kinematics so that they can be used to point an item to another one or to override entirely their transformation. To add constraints you have to use the Attribute Editor.

Look up for the Constraints attribute list.

click on the Add menu and choose the constraint you want to add to the stack. To remove a constraint, select it in the list in the and press the Del Key.

Point#

The point constraint, constrains the item position to the position of the targeted item.

Attribute Description
Target Set the target for which the current item will be constrained to

Orient#

The orient constraint, constrains the item rotation to the rotation of the targeted item.

Attribute Description
Target Set the target for which the current item will be constrained to
Aim Vector Sets the vector aiming the target
Up Vector Set the up vector

Scale#

The scale constraint, constrains the item size to the size of the target.

Attribute Description
Target Set the target for which the current item will be constrained to

Target#

The target constraint, constrains the item orientation to target the position of a referenced item. To target an item, you need to specify both up and aim vectors. This constraint is generally used to rig lights and cameras to a center of interest.

Attribute Description
Target Sets the item to target
Aim Vector Sets the vector aiming the target
Up Vector Sets the up vector

Surface#

The surface constraint, constrains an item position and orientation to the surface of an arbitrary scene objects. This constraint is very useful when you want to constrain items to geometries with deformation on for example. That way you ensure the item is following the underlying geometry whatever its deformation. In other words, you don't need to export locators from the animation package to parent your items to a specific surface anymore.

Cylinder constrained to the ground

Cylinder constrained to the ground

Cylinder still constrained to the ground even when the deformation changes

Cylinder still constrained to the ground even when the deformation changes

Attribute Description
Pick Target Invoke Clone Stamp tool to specify the target
Target Set the geometry used as target
Set Offset Invoke Translate tool to specify the constraint offset
Offset Specify the object's offset in constrained space
Orient Enable orientation constraint: align Up vector onto target normal
Set Orientation Invoke Rotate tool to specify the Up vector and roll
Up Vector Specify the object's vector to orient
Spin Specify the object's rotation around target normal

You can also directly constrain an object to a surface when using the Clone Stamp tool.

Parent#

The parent constraint parents the item to the target. It's basically equivalent of having all 3 orient, point and scale constraints referencing the same target.

Attribute Description
Target Set the target for which the current item will be constrained to

MOT Player#

Read a MOT animation file from disk to animate the item. MOT was an ascii motion file format introduced by LightWave 3D. This constraint is deprecated.

Attribute Description
Filename Filename of the MOT animation file
Frame Offset Set a time offset when reading the MOT animation
