Region Camera
Method #
This node generates a camera whose view is fixed to a particular plane/region of space. This is very useful for generating content with tracked effects from a physical space (e.g. Blacktrax). It’s advised to use real world measurements to set up the region of render/interaction space and then set a camera distance from the plane, as this will avoid issues trying to translate between the real world and the scene world.
Use the Axis, to set the direction of shooting to the plane. Most commonly Y, which is a top down view.
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 core behaviours of the node.
Parameter Details Orthographic Toggle the camera to be an orthographic camera with parallel perspective.
Axis Choose which axis the planar region views the scene from. i.e. X = Front On, Y = Top Down
Top Left X The top left X coordinate of the region
Top Left Y The top left Y coordinate of the region
Bottom Right X The bottom right X coordinate of the region
Bottom Right Y The bottom right Y coordinate of the region
Camera Distance Distance of the camera from the planar region being viewed.
Near Clip The closest distance that will be rendered. WARNING: Reducing this value too low can reduce the accuracy of aspects of the render.
Far Clip The 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.
Camera Priority Change the priority of the camera. If two or more cameras have the same priority, the highest camera node in the nodegraph heirarchy is used.

| Far Clip | The 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. |

| Name | Description | Typical Input |
|---|---|---|
| Included Objects | Select 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 Objects | Select 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 Modifiers | Apply the transforms of another node to this node. | Null |
| Target Node | Modifiy the rotations of the node to always direct the z axis towards the input. | Null |
| Local Transform Override | Apply the transforms of another node to this node, relative to its parent. | Null |
