A UE5 editor plugin that snaps one actor's transform to another — with per-axis control over translation, rotation, and scale.
- Actor-to-actor snapping with full undo/redo support
- Per-channel masking — choose exactly which X/Y/Z axes to snap for each transform component
- Inline options dialog — hold Alt while snapping to adjust options on the fly before confirming
- Right-click context menus — snap entries appear in both the viewport and World Outliner when exactly two actors are selected
- Persistent settings — defaults are saved per-project and exposed in Editor Preferences
- Reversible direction — snap A→B or B→A from the same selection
Select exactly two actors, then snap one to the other using either the right-click context menu or a keyboard shortcut.
| Command | Actor that moves |
|---|---|
| Snap A to B | First selected actor snaps to the second |
| Snap B to A | Second selected actor snaps to the first |
The context menu entries show the actual actor names so direction is always clear (e.g. Snap to SM_Chair).
By default, translation and rotation are snapped (all axes), and scale is left alone. This can be changed in the settings panel or per-operation in the inline dialog.
With exactly two actors selected, right-click in the viewport or World Outliner and open the Snap submenu. Two entries appear — one for each snap direction — labeled with the target actor's name.
SnapAToB and SnapBToA can be bound to any key in Editor Preferences → Keyboard Shortcuts → Oh, Snap!. No default bindings are set.
Holding Alt while triggering a snap (via keyboard shortcut or context menu) opens a modal dialog before the operation runs.
The dialog shows:
- The snap direction (
ActorA → ActorB) - Checkboxes for Translation, Rotation, and Scale, each with independent X/Y/Z axis toggles
- A Make Default checkbox to save the current configuration as the new default
Pressing Confirm (or Enter) runs the snap with those settings. Cancel (or Escape) aborts.
Tip: If your snap shortcut already includes the Alt key (e.g.
Alt+S), the dialog will open every time. To disable Alt detection, uncheck Alt Opens Inline Dialog in Editor Preferences → Level Editor → Snapping.
Each transform component has a section toggle (enable/disable the entire component) and three axis toggles (X, Y, Z). Disabled axes are skipped — the target actor's existing value is preserved on that axis.
| Component | Default | Notes |
|---|---|---|
| Translation | Enabled (all axes) | XYZ world location |
| Rotation | Enabled (all axes) | X=Roll, Y=Pitch, Z=Yaw |
| Scale | Disabled | Must be explicitly enabled |
Default snap options are saved per-project. To change them:
Editor Preferences → Level Editor → Snapping → Actor to Actor
Changes here apply to all subsequent snaps that don't use the inline dialog. The inline dialog's Make Default checkbox also writes to these settings.
