Expose Transform Helper 17

Inter face

Parameters rollout

These settings let you specify the exposed node,

a reference object other than the pa rent, and

rotation and timing parameters.

Expose Node—Theobjectfromwhichthevalues

are generated. Click the button, and then select

the object. Thereafter, the object name appears

on the button.

Local R efer ence Node—The object w hose

relationshipwiththeExposeNodeobjectisused

to generate local data for rotation, distance, and

angle. Click the button, and then select the object.

Available only when Parent is off.

By default, this is the parent object, but you can

turn off Parent and then specify a different object.

Parent —When on, the Local Reference Node is set

automatically to the parent of the Expose Node.

When off, you can pick an object to refer to for

local data. Default=on.

This is used by the Local Euler Angles, Distance To

Reference, and A ngle par a meters. If the object has

no parent and you don’t specify a Local Reference

Node object, these fields use the world center

(0,0,0) as the reference node.

Rotation Or der—These three settings determine

the order in which the Expose Transform helper

will look for an Euler rotation.

This parameter corrects for anomalies that can

be introduced when a local rotat ion value is

generated in relation to other rotation values. For

example, when Z Order is set to XYZ, the Z value

is generated in reference to X and then Y. Or when

X Order is set to ZXY, the Z value is generated

directly in reference to the parent, regardless of X

and Y rotations.

Strip NU Scale—When on, removes any

non-uniform scaling that could influence the

rotation data. It does not st r ip non-uniform

scaling from the object; only from the values

generated.

Use T i me Of fs et —When on, lets you specify a

frame other than the current one from which

to gather data. The Offset value is added to the

current frame to derive the frame from which data

is gathered.

For example, if the current frame is 20 and you

w ish to gather data from frame 15, turn on Use

Time Offset and set Offset to -5.
