title: Lattice
order: 11

Lattice bends and stretches a shape with a cage of points. Add it and a cage fits around the shape; drag any cage point in the viewport and the whole field sculpts along with it. No extra objects, no mode switching.

## Adding a lattice

- **Modifier panel**: *Add Modifier → Lattice*
- **Pie menu** (`Q`): the *Lattice* button in the South wedge's modifier grid
- **Right-click menu**: *Modifiers → Lattice*

Lattice is added to every selected shape, with a 3 × 3 × 3 cage fitted to the shape's bounds. It goes to the end of the stack, so it deforms the finished shape.

## Editing the cage

With the object active and selected, the cage draws in the viewport as a violet wireframe with a dot on every control point. Drag a dot and the shape deforms live; the drag follows the view plane. `Space`, `Enter` or releasing the mouse confirms, `RMB` or `Esc` puts the point back. Parts of the shape outside the cage do not move.

## Parameters

- **Points**: control points per axis, X / Y / Z, each `2–8` (default `3 3 3`). Changing a count rebuilds the cage at rest.
- **Interpolation**: how the field moves between control points: *Linear*, *Cardinal*, **B-Spline** (default, the smoothest), or *Catmull-Rom*. One family for all three axes.
- **Fit Cage**: refit the cage box to the shape's current bounds after the shape changed. Control displacements reset, since the grid they anchored to has moved.
- **Reset Points**: return every control point to rest. The cage box stays where it is.

The pie's East wedge shows a Lattice row with the three point counts and the interpolation dropdown; *Fit Cage* and *Reset Points* are panel-only.

## Folding

A cage pushed past the point where it folds over itself breaks the surface into speckled holes and slows the render.

- While dragging, the point is held at the fold limit and its dot turns **red**.
- A cage that is already folded (from an old file, or after switching interpolation) draws all its dots red, and the modifier shows a warning in the panel, in its header, and in the pie:

> *This cage folds — the deformation has no inverse, so the shape breaks up here. Reset Points, or try a smoother interpolation.*

**Reset Points** or a switch to *B-Spline* clears it. The drag guard can be turned off in *Preferences → Debug → Lattice Fold Guard*.
