have enough mesh resolution for the desired
deformation.
2. Do either of the follow ing:
• To deform anywhere on the object, remain
at the object level, or work at a sub-object
level with no sub-objects selected.
• To deform only specific areas of an object,
go to a sub-object level and then select the
sub-objects in the area to deform.
3. On the Paint Deformation rollout, click
Push/Pull.
4. Set Push/Pull va lue to a negative value to push
into the object surface, or to a positive value
to pull the surface outward. The higher the
absolutevalue,thegreatertheeffect.
5. Set Brush Size and Brush Strength.
6. Position the mouse cursor over the surface to
be deformed.
Asyoumovethemouse,the“brush”reorients
dynam ically to show the normal direction of
the portion of the mesh currently under the
cursor. You can use the normal direction of
deformed surfaces as the push/pull direction by
choosing Deformed Normals.
7. Press the mouse button and drag to deform the
surface. If you paint in the same spot repeatedly
without lifting the mouse button, the effect
is cumulative up to the ma ximum Push/Pull

Paint Deformation has three modes of operation:
Push/Pull, Relax, and Revert. Only one of these
modes can be active at a time. The remaining
settings control the effect of the active deformation
mode.
For any mode, choose the mode, change settings
as necessary, a nd then drag the cursor over the
object to paint the deformation.
To paint deformation anywhere on the object,
remain at the object level, or work at a sub-object
level with no sub-objects selected. To deform only
specific areas of an object, go to a sub-object level
and select the sub-objects in the area to deform.
Push/P ull—Moves vertices into the object surface
(push) or out of the surface (pull). The direction
and extent of pushing or pulling is determined by
thePush/PullValuesetting.
Tip: To reverse the Push/Pull direction while
painting,pressandholdALT.
