uCamera
USD camera and film-back control
Creates or configures a USD camera with projection, clipping, exposure, focus, film back, lens shift, transform and stage-export controls.
uCamera
DaVinci Resolve · Fusion
uCamera is the camera node for Fusion USD workflows. It defines both optical properties and the camera transform inside a USD stage, then passes that camera downstream to uMerge and uRenderer.
Overview
What uCamera does
uCamera is the camera node for Fusion USD workflows. It defines both optical properties and the camera transform inside a USD stage, then passes that camera downstream to uMerge and uRenderer.
Mental model
Think of uCamera as the lens and tripod for the USD stage: Controls define how the camera sees, Transform defines where it is, and stage export determines how the camera is packaged in the USD graph.
Common uses
USD camera creation
Film-back matching
Depth-of-field metadata
Animated camera transforms
USD stage export
Flow anatomy
Inputs & outputs
The port structure shows how this node fits into a Fusion graph.
SceneInput
Optional USD stage to which the camera is added or in which it is configured.
uCamera
Fusion node
SceneOutput
The resulting 3D scene or scene object.
Inspector
Important parameters
Start with these controls before reaching for more complicated workarounds.
Clip / Near and Far
Sets the camera’s near and far clipping planes.
Exposure
Stores/controls camera exposure metadata where supported.
Focal Length
Sets lens focal length and therefore field of view.
Focus Distance
Sets the camera focus distance used by depth-of-field calculations.
F Stop
Sets the virtual aperture f-stop used by depth-of-field calculations.
Film Back / Horizontal Aperture and Vertical Aperture
Sets the virtual film-back aperture dimensions.
These values affect the relationship between focal length and field of view.
Lens Shift X / Lens Shift Y
Sets the horizontal and vertical Lens Shift.
Shutter Close / Shutter Open
Sets the opening and closing times of the virtual shutter interval.
Stereo Role
Chooses whether the camera acts as the left, center or right member of a stereo rig.
Control Visibility / Show View Controls
Shows View Controls in the Viewer for setup or diagnostics.
Viewer guides do not normally change the rendered image unless the control explicitly says otherwise.
Control Visibility / Frustum
Shows the camera frustum in the 3D Viewer.
Use it to see what falls inside the camera field of view.
Control Visibility / View Vector
Shows the camera viewing direction in the 3D Viewer.
Control Visibility / Near Clip and Far Clip
Shows Near Clip and Far Clip in the Viewer for setup or diagnostics.
Control Visibility / Focal Plane
Shows the camera focal plane in the 3D Viewer.
Translation X/Y/Z
Sets translation on the X, Y and Z axes.
Rotation Order and Rotation X/Y/Z
Sets Rotation Order and Rotation on the X, Y and Z axes.
Pivot X/Y/Z
Sets the pivot position on the X, Y and Z axes.
Use Target
Orients the camera toward a target when available.
Export as Separate Stage
Packages the camera as a separate USD stage/layer.
Practical setup
A reliable workflow
- 1
Add uCamera to the USD branch.
- 2
Set projection and focal length.
- 3
Set clipping and film-back values.
- 4
Position the camera using Transform.
- 5
Use target orientation only when it simplifies the shot.
- 6
Select the camera in uRenderer and verify framing.

Examples
Where this node fits in real work
USD hero camera
Create a camera, merge it with scene geometry and render through uRenderer.
uShapeuCamerauMergeuRenderer
Matched plate camera
Use film-back and focal-length controls to match a known plate/camera setup.
uLoaderuCamerauMergeuRenderer
Troubleshooting
Common mistakes
Adjusting object transforms to compensate for an incorrect camera.
Using an inappropriate near clip and cutting geometry close to camera.
Forgetting to select the intended camera in uRenderer.
Production notes
Practical tips
Keep film-back and focal-length values documented when matching external 3D work.
Animate the camera in USD space rather than moving the entire stage when camera motion is intended.
Check clipping early in large-scale scenes.
