Control (UI) Default Value Function
baseAimAxis 0.0, 0.0, -1.0 The axis of the base object that is pointed at the target.
Adjusting these values changes the axis of the object that is
aimed at the target.
baseUpAxis 0.0, 1.0, 0.0 The axis of the base object that is pointed upwards relative to
the target.
Adjusting these values changes the rotation of the base object,
while keeping the aim constant.
targetUpAxis 0.0, 1.0, 0.0 The world space axis from the target object's position that
defines the up direction for the base object
Adjusting these values changes the axis of the base object's up
axis.
allowMissingTargets No When set to Yes, silently ignore the constraint if its target is not
in the Scene Graph.
When set to No, produce an error on constraint resolution if the
target is missing.
addToConstraintList No Adds base path to globals.constraintList at /root/world.
This is only rarely necessary to settle the resolution order for
cyclical constraint dependencies (A is constrained to B, and B is
constrained to A).
setRelativeTargets No Stores target paths in the scene graph constraint definition as
paths relative to the base path.
Targets should still be specified as abolute paths in this node's
parameters.
Alembic_In
The Alembic_In node enables you to import Alembic assets. Alembic is an open source scene information interchange
framework which distills complex, animated scenes into non-procedural, application-independent, baked geometric
results. It stores only the baked information and not how that information was obtained. You can export to Alembic
from most popular 3D applications.
