Offset & Scale¶
OVB gives you two ways to move and scale imported art, and they land in very different places. Knowing which is which saves a lot of confusion downstream.
Both gizmos work the same — drag inside to offset, drag a corner handle to scale, and drag the ⊕ pivot to choose what the scale grows from. Only the colour differs: blue moves one art layer's vector, green moves the whole drawing.
Art-layer transform — the blue gizmo¶
Selecting (soloing) an art layer shows its blue gizmo. Scale and Offset here apply directly to that art layer's vector — the geometry itself is transformed. Use it to fit or nudge one layer relative to the others (line art vs its colour fill, say).
- Lives on the art layer (per subartlayer).
- Bakes into the vector — it changes the imported geometry.
- Fields: Scale X / Y and Offset X / Y in the Art Layer & Sequence card.
Peg transform — the green gizmo¶
On the composite of a drawing that has a peg (a +Peg node), the green gizmo appears. Scale and Offset here ride on the peg, not the drawing — the whole drawing moves as one, and the values stay live and animatable in Harmony.
- Lives on the drawing's peg (whole-drawing).
- Rides on the peg — the vector content stays clean, full-resolution, editable.
- The green box scales the entire drawing about its centre.
The pivot — what the scale grows from¶
Both gizmos carry a pivot: a small circle with a cross, in the gizmo's own colour (with a dark halo so it reads over light art). It starts at the centre of the box, and it is what a corner drag scales from.
- Drag the pivot anywhere inside the box to move it. Then drag a corner: the pivot stays put and the box grows or shrinks away from it — scale a character from the soles of their feet instead of from the middle, and the feet do not drift.
- Alt while dragging a corner scales from the centre, ignoring the pivot. With the pivot still at the centre both are the same, so Alt only starts to mean something once you have moved it.
- Shift keeps doing what it always did — it flips the corner drag between uniform and free (the link button sets the default; Shift inverts it for that drag).
- The blue pivot is per track: each art layer scales about its own point, so line and colour can grow from different places.
- Switching to another drawing puts the pivots back at the centre. A pivot belongs to the art it was chosen on; carrying it over would make the next drawing scale from a point picked for something else.
The pivot is an authoring aid, not a new attribute
Moving the pivot does not write a pivot onto the peg. What it produces is a scale plus a compensating offset — exactly what moving the pivot in Harmony's own animate mode does. The peg is created, and stays, with its resting pivot at 0,0, so nothing unexpected shows up in the scene.
Which should I use?¶
| Art-layer (blue) | Peg (green) | |
|---|---|---|
| Affects | one art layer's vector | the whole drawing |
| Where it lands | baked into the geometry | on the peg (live/animatable) |
| Use for | aligning layers to each other | positioning/scaling the drawing in the scene |
Full-res content, editable transform
Because the peg carries the transform, a +Peg drawing imports its content at scale 1.0 (full resolution) and the scale/offset stay as editable peg values in Harmony — you can re-tweak or key them later without re-importing.
