Move—
Moves the selected points.
Mo ve is a flyout. The alternative buttons constrain
texturepointstomoveeitherverticallyor
horizontally.
Rotate—Rotates the selected points.
Scale—Scales the selected points. This is a flyout
that lets you choose between uniform scale,
nonuniform scale in the surface’s U dimension, or
nonuniform scale in the surface’s V dimension.
Pan—Pans the surface view .
Zoom—Zooms in or out on the surface view.
Zoom Wind ow—Zoomstoawindowyoudragon
the surface view.
Zoom Ex t ents—Zooms to t he extents of the surface.
Lock Selection—Locks the active selection set. You
can turn this on to keep from accidentally selecting

If you right-click while in the image, a pop-up
menu lets you switch between Select, Move,
Rotate, and Scale. This is an alternative to using
the toolbar.

Buttons and Weight
These controls are comparable to editing controls
on the rollouts for point sub-objects. (The Open
button works differently.) These controls are
disabled while you create a new curve on surface.
Refine—Addspointstothecurve.Thisdoesnot
change curvature. For point curves, the curvature
can change, but only slightly.
Insert—(Not available for point curves on
surfaces.)
Clo se—Closes the cur ve.
Fuse—Fuses two points.
Weigh t—(Not available for point curves on
surfaces.)
Delete—Deletes the selected points.
Open—Opens the curve by unfusing the points
wherethecurvewasoriginallyclosed.
Unfuse—Unfuses the selected points.
Remove Animation—Removes animation
controllers from the selected points or CVs.

This dialog lets you edit the texture surface for a
surface sub-object. It is available when you have
chosen User Defined as the sub-object’s texture
surface method.
A texture surface is associated with the surface
sub-object. The texture surface is used to control
how materials are mapped. In effect, changing
thetexturesurfacestretchesorotherwisechanges
the UV coordinates for the surface, altering the
mapping.
The Edit Texture Surface dialog shows a 2D view of
the texture surface. You can also ed it user-defi ne d
texture surfaces directly in 3D viewports, using the
