uTransform
USD prim transform
Applies translation, rotation, pivot and scale to selected USD prims, with prim-selection filtering and optional separate-stage export.
uTransform
DaVinci Resolve · Fusion
uTransform modifies scene objects inside a USD stage rather than moving pixels. It is useful for shot layout, asset placement, group transforms and targeted changes to specific prim paths.
Overview
What uTransform does
uTransform modifies scene objects inside a USD stage rather than moving pixels. It is useful for shot layout, asset placement, group transforms and targeted changes to specific prim paths.
Mental model
Think of uTransform as Transform3D for selected USD prims: first decide which scene objects are affected, then apply the transform in stage space.
Common uses
USD asset placement
Group transforms
Prim-specific animation
Scene layout corrections
Flow anatomy

Inspector
Important parameters
Start with these controls before reaching for more complicated workarounds.
Invert Prim Selection
Applies the operation to everything except the selected prims.
Translation X / Y / Z
Moves the selected prims in stage space.
Rotation Order
Defines rotation-axis evaluation order.
Rotation X / Y / Z
Rotates selected prims.
Pivot X / Y / Z
Sets the transform pivot.
Lock X/Y/Z
Links the X, Y and Z values for scale.
Scale
Sets the overall scale.
Use Target
Orients the transformed selection toward a target when supported.
Export as Separate Stage
Packages the transformed result as a separate stage layer.
Practical setup
A reliable workflow
- 1
Identify the exact prim paths to transform.
- 2
Use Selected Prims rather than moving the entire stage when only one asset should change.
- 3
Set pivot before rotation or scale if the default origin is unsuitable.
- 4
Animate translation/rotation as required.
- 5
Merge the result back into the shot stage and render-check.

Examples
Where this node fits in real work
Place an imported USD asset
Load the asset, transform only its root prim and merge it into the scene.

Animate a USD object
Keyframe translation/rotation on the selected prim while leaving the rest of the stage untouched.

Troubleshooting
Common mistakes
Using an overly broad prim selection and moving unintended scene elements.
Ignoring the pivot before rotation.
Applying transforms both in the source DCC and again in Fusion without tracking the combined result.
Production notes
Practical tips
Keep prim selections explicit and readable.
Transform asset roots when possible instead of many child prims.
Use separate-stage export when the transform should remain a clean override layer.
