You edit Point on Poly constraints primarily to adjust the position of constrained objects relative to their target mesh.
To edit Point on Poly constraint attributes
- Select a Point on Poly constraint node, or select a Point on Poly constrained object.
- Do one of the following to view the Point on Poly constraint attributes:
- In the
Channel Box, click the pointOnPolyConstraint under the
SHAPES heading to display the Point on Poly attributes.
- In the
Attribute Editor, select the pointOnPolyConstraint tab and expand the
Point On Poly Constraint Attributes section and the
Extra Attributes section.
- Adjust attributes as required.
For example, use the
Offset Translate and
Offset Rotate fields to adjust the constrained object’s position relative to the target mesh.
- (Optional) If you have more than one constrained object, you can adjust the weight value and the UV position of each object. (In the
Attribute Editor, these options are available in the
Extra Attributes
section.)
Note: The target object must have valid U and V coordinates or the constraint has no effect. For example, a default cube has no valid UVs at 0, 0 so you must set the U and V parameters on the pointOnPolyConstraint node to UV coordinates so that they correspond to a point on the mesh. If you want to constrain entire objects, consider using a
Point constraint. See
Create a point constraint.
See
pointOnPolyConstraint node for descriptions of the attributes available.
