Exposable Null

Exposable Null

A transform which can be easily exposed for control by a media server.


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.


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.

Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.

These properties control the core behaviours of the node.

Exposable Position RotationYou must expose this value for the media server to be able to control the Exposable Null
