Move components with the Tweak mode
Transform objects and components
Change the pivot point
Move, rotate, or scale components with reflection
When
editing a model with the transformation tools you often need to
make changes symmetrically. For example, when modifying a character's
head, if changes are made to the top of the left ear, you may also
want the top of the right ear to also be affected. The Reflection setting
lets you do this.
You can select a component(s) on one half of
the model, and the Reflection setting will highlight
the affected component(s) on the opposite half of the model with
a white color. This is called the color feedback.
To
move, rotate, or scale components on an object using the Reflection setting
- In
the scene view, select the components you want to move, rotate,
or scale on one half of the surface mesh.
- Select
the appropriate transformation tool by doing one of the following:
The tool settings for that transformation tool
appear.
- In
the Tool Settings Editor, turn
the Reflection setting on.
The corresponding component(s) across the reflection
axis is highlighted in white.
- When
you subsequently move, rotate, or scale the selected component(s), the
corresponding highlighted component(s) are also transformed on the opposite
side of the reflection axis.
- With
the other reflection settings you can specify:
- whether
the Center of reflection is at the origin or based on the bounding box
of the object.
- set
the Tolerance for the reflection (that is, how closely the selected
component and the component across the reflection axis have to mirror
each other in order for mirroring movement to occur).
- the Reflection
axis which the reflection occurs across.
NoteReflection settings stay consistent when
switching between transformation tools. For example, if you turn
on reflection when the Move Tool is active and then you select the
Scale Tool, reflection will still remain on.
The manipulator indicates the axis along which
the reflection takes place:
NoteThe position of the reflection plane on
the manipulator doesn’t correspond to the actual origin of reflection
(which may be outside of the current view); it’s just a visual indication
of the reflection plane (x, y, or z).
Reflection works differently depending on whether Soft
Selection is turned on or off.
When Soft Selection is
turned off and you select a component, Maya attempts to find a component
on the opposite side of the seam and include it in the current selection.
You can use the Reflection Settings to reflect
transformations on a model that is not perfectly symmetrical.
When Soft Selection is
turned on and you transform geometry, Maya mimics the same modification
on the opposite side of the seam regardless of whether or not a
component exists there.
Notes on the using the Reflection setting
- The
reflection color feedback automatically appears whenever the reflection
setting is turned on and cannot be optionally turned off. The color feedback
will not display if you momentarily edit an attribute in the Channel
Box. The reflection color feedback will automatically
update whenever the reflection center, axis, or tolerances are changed.
- The
reflection color feedback only appears on NURBS surfaces when the surface
is displayed in shaded mode. When textures are applied to the shading
material on a NURBS surface they will temporarily not display on the
surface while the transformation tool with reflection settings are
in use.
- Reflection
color feedback does not appear on subdivision surfaces.
- The
Reflection color feedback indicates the components affected by the current
selection. In some cases, components may or may not appear with color
feedback based on the original component selection, reflection center,
axis, or tolerances. For example, when the Center setting is set
to Bounding box, when the object shape is irregular, there may not
be a corresponding component to highlight based on the shape of
the bounding box. In this situation you should try setting the Center
setting to Origin, and set the Move setting to either Local or Object
space.
