•
Animate: A pop-up menu that sets the interpolation for animated 3D rotation channels to
one of two options:
•
Use Rotation: The default interpolation method. Layer rotates from its start angle to its
final angle. Depending on the animation, the layer might twist before reaching its final
orientation (the last keyframed value). For example, if the X, Y, and Z Angle parameters are
animated from 0 degrees to 180 degrees in a project, the layer rotates on all axes before
reaching its final orientation.
•
Use Orientation: This alternate interpolation method provides smoother interpolation but
does not allow multiple revolutions. Use Orientation interpolates between the layer’s start
orientation (first keyframe) to its end orientation (second keyframe).
Note: The Rotation parameter must be keyframed for the Animate parameter options to have
any effect.
•
Scale: A slider that controls the percentage representing the layer’s scale, relative to its original
size. By default, the horizontal and vertical scale of a layer is locked to the layer’s original
aspect ratio—represented by a single percentage. Click the disclosure triangle to display
independent percentages for the X, Y, and Z scales of the layer.
Note: Setting a layer’s scale to a negative value flips the layer.
•
Shear: Value sliders that define the X and Y shear of the layer. A layer with no shear has X
and Y shear values of 0. Positive values shear in one direction, while negative values shear in
the other.
•
Anchor Point: Value sliders that define the X and Y position of the anchor point relative to the
center of the layer. Coordinates of 0, 0 center the anchor point in the bounding box defining
the outer edge of the layer. Click the disclosure triangle to expose an additional value slider
defining the Z position.
Blending parameters
•
Opacity: A slider that sets the transparency of the layer. For more information, see
page 227.
•
Blend Mode: A pop-up menu that sets the Blend Mode of the layer. For more information, see
on page 229.
•
Preserve Opacity: When this checkbox is selected, the layer appears only where another layer is
visible behind it in the composite. The front layer uses the opacity value of the layer behind it.
For more information, see
on page 228.
•
Casts Reflections: A pop-up menu that determines whether a layer casts a reflection. Choose
from three options:
•
Yes: The layer is seen reflected in nearby reflective layers.
•
No: The layer is ignored by reflective surfaces.
•
Reflection Only: The layer becomes invisible, but will appear in reflective surfaces around it.
Note: Reflections are only visible when layers are in a 3D group. For more information on 3D
groups, see
on page 927.
Lighting parameters
The Lighting parameter controls appear only when the parent group is set to 3D.
•
Shading: A pop-up menu that sets how a layer responds to lights in the scene. There are three options:
•
Inherited: The layer uses the shading value of its parent.
•
On: The layer can be lit.
•
Off: The layer ignores scene lights.
