What changed in Chisel 4.1.

## 4.1.0

Version 4.1 is about **shaping**. Five new modifiers bend, sweep, carve, revolve and smooth your models. Chisel now also tracks GPU memory, so heavy scenes slow down rather than fail.

### New

- **[Smooth](modifiers/smooth.md)**: one radius rounds the whole model.
- **[Lattice](modifiers/lattice.md)**: bend and stretch a shape with a cage of points.
- **[Carve](modifiers/carve.md)**: cut with a grown copy of another shape.
- **[Revolve](modifiers/revolve.md)**: spin a profile around an axis.
- **[Sweep](modifiers/sweep.md)**: run a shape along a path of points.
- **[Bisect planes have handles](modifiers/bisect.md#gizmo)**: slide, blend, and round corners.
- **[Gizmos can follow the active object, all selected, or stay off](render-engine/gizmos.md)**.
- **[Clean Mods](operations/clean-mods.md)**: remove every broken modifier in one click.
- **[Convert Legacy Curve](operations/convert-legacy-curve.md)**: turn an old curve shape into an Ngon, Revolve or Sweep.
- **[Subdivision Level](render-engine/quality.md#brick-detail)**: one detail slider for the whole scene.
- **[Auto Cell Size](render-engine/performance.md#auto-cell-size)**: detail no longer depends on object size.
- **[Chisel knows your GPU memory](primitives/mesh.md#when-a-grid-does-not-fit)**: too-big conversions are refused up front instead of failing.
- `Space` confirms a drag, like `Enter`.
- [Local view](render-engine/display.md#local-view) isolates Chisel shapes.

### Performance

- Dragging stays smooth on heavy scenes.
- Sliders only update the object you are editing.
- Orbiting a heavy scene no longer re-renders every frame.
- Going back to a position you already had is instant.
- No more freeze when you release a drag.
- Apply Modifiers and Convert to Mesh are twice as fast.
- Rendering is about 20% faster.
- Mesh shapes use half the GPU memory.

### Fixed

- Crash to desktop on Intel integrated GPUs.
- A graphics error no longer ends the render session.
- Restarting the renderer no longer leaks GPU memory.
- Mesh resolution above 256 crashed Blender.
- Apply Modifiers came out blocky.
- Selection outline and snapping did not follow every edit.
- Carve painted the target's colour into the pocket.
- Curve tubes were not smooth.
- Sweep profiles twisted along straight legs.
- Undo lost a shape's material.
- Moving an object with a parent was sometimes ignored.
- F12 ignored Render Region and orthographic cameras.
- A drag that hit an error left a mess behind.
- Replace Original, Apply and Duplicate could lose data.
- Picking a target in the modifier panel added a second shape.
- Plain meshes lost their modifier stack under the Chisel engine.
- Matcap choice was not saved by name.
- Dragging Blend to zero switched Blend off.
- Rebake SDF did not clear the *"SDF is stale"* banner.
- Mesh shapes piled up in memory.
