Exposable Null
A transform which can be easily exposed for control by a media server.
Exposable Null
Method #
This node allows supported media servers to have simplified 6DOF control of a Null. This is useful for managing objects which are tracked by stage automation or spatial tracking systems (e.g. Blacktrax, OptiTrack).
When the Exposable Position Rotation attribute is exposed, it is recognised by the media server as a controllable Null and it provides higher level controls. Generally, you would parent objects, emitters etc to the Exposable Null.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
These properties control the core behaviours of the node.
Parameter Details
Flip Z Axis Flip the Z axis of the values passed by the media server
Exposable Position Rotation You must expose this value for the media server to be able to control the Exposable Null
Inputs
