Adjust Transform rollout
You can t ransform an object and its pivot
without affecting its children using t he buttons in
Adjust Tr ansform rollout. Adjusting an object’s
transforms has no effect on any children linked
to that object.
Procedure
To sca le a parent without scaling the children:
1.
Select the p arent object in a hierarchy.
2. On the Hierarchy panel click the Pivot button
if it’s not already on, then on the Adjust
Transformrollout,clickDon’tAffectChildren.
3. Scale the parent object.
Thechildrenwillremainunaffected.
Tip: Never use non-uniform scale at the object
level for objects in a hierarchical chain. Always
go to the sub-object level when you do a
non-uniform scale on hierarchically linked
objects.
To reinitialize the scale of an object:
1.
Select an object.
2. IntheAdjustTransformrollout>Resetgroup,
click Scale.
The XYZ values are re-initialized to 100%.

Don’tAffectChildren—Limits transforms to the
selected object and its axis, not to its children.
This is very useful when work ing with bones and
other hierarchies. If you need to make a particular
bone or object longer or shorter, select the object

Reset group
Transf orm—Resets the orientation of an objects
local axis coordinates to a lign w ith the world
coordinate system, regardless of the current
orientation of the object.
This does not affect descendants.
When applied to
closed groups, it aligns the
dummy node of the parent, but keeps the children
in the same place. It reorients and resizes the
dummy node to correctly bind the children of the
group.
Scale—Resets the s cale values in the transformation
matrix to reflect the new scale of the object. There
is no visual change in the object.
