Exposable Camera

Exposable Camera

Places a camera designed to be controlled directly by a media server when running as a block.

Method #

This camera is designed to be controlled directly by a media server when running as a block. This is useful for Augmented Reality (AR/XR) camera tracking setups, where the media server is passing through the camera tracking data.

See this video to see this feature in action.

When the Exposable Camera Values attribute is exposed, it is recognised by the media server as a controllable camera and it provides higher-level controls in the media server.

Nodes parented to this node will generally follow the standard parent-child relationship with nodes in Notch, with a couple exceptions:

  • Most Post-FX nodes will only run when viewed through a camera when connected to the camera.
  • The Camera Focus Target controls the focus position and attributes for the camera.

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.

ParameterDetails
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.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

ParameterDetails
Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Field Of View YThe angle to modify the FOV with. Only functions with Use Field OF View Y enabled.
Aspect RatioDefines the ratio between the cameras width and height.
Near ClipThe closest distance that will be rendered. WARNING: Reducing this value too low can reduce the accuracy of aspects of the render.
Far ClipThe furthest distance that will be rendered by this camera. WARNING: Increasing this value too high, without increasing the Near Clip can reduce the accuracy of aspects of the renderer. Generally best left untouched.
Focal Plane DistanceThe distance from the camera that is sharp, when utilising Depth of Field. Requires a Depth of Field Post-FX node to be used.
Focal RangeThe range around the focal plane that is sharp. Requires a Depth of Field Post-FX node to be used.
Focal BlurinessHow blurry the focal point is. Requires a Depth of Field Post-FX node to be used.
PriorityChange the priority of the camera. If two or more cameras have the same priority, the highest camera node in the nodegraph heirarchy is used.
Flip Z AxisFlip the Z axis of the values passed by the media server
Exposable Camera ValuesYou must expose this value for the media server to be able to control the Exposable Camera

Inputs

Included ObjectsSelect nodes will be included in the final rendering from this camera. Once a node is connected, all unconnected nodes will be treated as excluded.3D Object
Excluded ObjectsSelect objects to be ignored by this camera. These objects will not be rendered, but will otherwise be generated and impact performance. Once a node is connected, all unconnected nodes will be treated as included.3D Object
Transform ModifierApply the transforms of another node to this node.Null
Target NodeModifiy the rotations of the node to always direct the z axis towards the input.Null
Local Transform OverrideApply the transforms of another node to this node, relative to its parent.Null
