Devil Designer 0.13.0 - New Simulation Engine & Live Grab

What's new in 0.13.0

A new simulation engine built on Geometry Nodes replaces Blender's Cloth modifier.

• Grab cloth while it simulates. Pull or push it live with a radius ring at the cursor. Ctrl+wheel sets the radius.
• Keep now refines the drape at your Quality setting and checks it against the body.
• Requires Blender 5.2 or newer.

Known issues

• Avatars with the whole torso removed: garments can fall off and Keep refuses.
• Skirt hems can crumple at one side.
• Cloth snaps a little when released from Grab.
• Tested on one NVIDIA PC so far.

Details

Simulation

• Simulate runs until you pause and accepts live input. About 30 FPS while grabbing on an avatar of about 90k triangles, measured on one PC.
• Sewing, pins, tacks, body contact and self-contact all run in the new engine.
• Your frame rate and timeline return after Keep or Reset.

Grab

• The camera stays where you put it, and the wheel zooms as usual.
• Pull follows your hand across the view. Push presses along the surface.

Fixes

• Keep no longer crashes on seams with points that have no cloth around them.
• Library garments saved with older settings load at the nearest allowed value.
• Changing Quality after draping no longer blocks Keep.
• A refused Simulate leaves your timeline untouched.
• Escape and clicking outside close menus in Grab.

Also known

• Fabrics are not calibrated against real cloth, and some look alike.
• Cloth can be pulled through itself while held.
• Small avatars may need sleeve fixes on the tee.
• If you change pose or shape keys, Reset and simulate again.

Devil Designer 0.12.0 - Native UI, Arrangement & Selection Tools

What's new in 0.12.0

Avatar Picker (Native Object Field)

• Rebuilt the Body card's Avatar selector as a native Blender-style object field with search-in-place, scrollable scene mesh listings, clear button, and a viewport eyedropper.

Arrangement Points & Symmetrical Placement

• Arrangement points now appear as clean surface discs on the avatar with realistic perspective, distance scaling, and body mesh occlusion.
• Placing a linked pattern piece onto a mirrored arrangement point automatically places its twin piece symmetrically in one step.

Calmer 2D Sewing Lines

• Seam lines now adapt dynamically across three attention levels: quiet badges and outlines when idle, single link lines when connected, and full detail when actively selected or hovered.

Mouse Transform Frame & Multi-Selection

• Selecting patterns, points, edges, or internal paths displays an interactive transform frame with corner scaling handles, rotation knob, and free translation.
• Includes angle (15°) and scale (10%) snapping with Shift, pivot repositioning with Alt, box and lasso selection modes, and live preflight ghosts showing transform safety.

Body-Checked Arrangement Placement

• 3D arrangement placement includes body-checked wrapping with real-time preview on hover, configurable wrap/flat modes, clearance distance adjustments, and conflict guards against duplicate extension installs.

Settled Cloth Shaping & Safe Keep

• Direct brush shaping on settled cloth drapes with safe Keep mesh generation and clearer user guidance for invalid states.

Native Interface & Theme Consistency

• Minimal workspace metrics, padding, outlines, and iconography align closely with native Blender layouts and active UI themes.

Performance & Code Cleanup

• Removed legacy unreachable code paths across the editor and math modules for a lighter package and smoother drafting experience.

• Built-in fabric presets calibrated against real textile physical behavior.
• Performance fix eliminating editing lag during pattern drafting.
• Compact native-feel interface pass with pixel-exact borders and an icon dock.
• Fixes for canvas rendering errors, with new automated draw coverage.
• Packaging updates for Blender Extensions submission readiness.

Known issue: a newly created seam may start in the wrong direction — select the seam and press B to reverse. A fix is planned.

Devil Designer 0.10.0 - Elliptical Arrangement, Simulation States & Sewing Preview

Arrangement and simulation

• Arrangement volumes are now elliptical and mesh-only: pieces wrap the body's real cross-section at each row's height.
• Per-piece simulation states: Freeze, Deactivate, Strengthen (right-click a piece, Simulation).
• Pre-sim sewing preview: see every actual seam pairing, direction arrows and mismatch warnings in 2D and 3D before you Simulate.

Known issue: a newly created seam may start in the wrong direction - if a seam pulls wrong, select it and press B (Reverse). A fix is planned.

Devil Designer 0.9.0 - Linked Editing, Layering & Fit Tools

Linked pattern editing

• Explicit linked twins mirror point, handle, topology and internal-path edits in both directions. Apply or remove linked editing for existing pieces; layout and avatar arrangement remain independent.
• Links survive undo/redo, save/reopen and library refits. Cloning and sewing remain explicit actions, never automatic. Included from PR #19.

Layer garments with Wear over

• Kept garments can collide with the next simulated garment. Wear over selects which kept layers participate; the body and other scene colliders remain included. Included from PR #20.
• Use High simulation quality for layering. The controlled shirt/jacket penetration gate uses High and a 2 mm tolerance; Standard measured 2.63 mm and exceeded that gate. This is a known limit, not a collision guarantee for arbitrary clothing or initial intersections. Layered-simulation performance remains a separate follow-up.

Fit map and optional seam Shrink

• F toggles the display-only fit map for inspecting compression and stretch; Home fits the 2D design. The map is not a pressure or fit guarantee.
• Seam Shrink offers opt-in 0/10/20/30 settings with persistence and undo/redo. Calibration is based on Cotton fixtures, not universal fabric or garment accuracy. Included together from PR #21.
• Nonzero Shrink uses 1 mm self-collision for that garment and can change folds and drape away from the seam. All-zero garments retain their original behavior. Local contraction calibration uses a same-physics diagnostic reference, not the normal 3 mm zero garment.

Faster arrangement-point display

• Cached arrangement geometry/GPU batches and GPU projection remove the measured H-overlay bottleneck: the representative scene improved from about 39 FPS to the 144-FPS ceiling with points enabled.
• Display-only fix: arrangement/placement math, H semantics, colors, sizes and picking are unchanged. Included from PR #22; full measurements and limitations are recorded in ARRANGEMENT_DISPLAY_PERFORMANCE.md.

Verified release

Includes all four feature PRs merged since v0.8.0: #19, #20, #21 and #22. Release metadata PR #23 introduces no application behavior changes.
Source: 4105553 (master, PR #23).
All nine Blender background suites, seven native GUI suites, unit tests, Blender extension validation, Python token/AST Rule Zero, dead-code/unused-import and publication checks passed on merged master. Python 3.11 and 3.13 remote checks passed. All 76 ZIP payloads match this source.
Tested in Blender 5.2.3 LTS; requires Blender 5.2+.

Devil Designer 0.8.0 - Cut Tools & Live Avatar Arrangement

Cut patterns without leaving the canvas

• Cut and Cut & Sew sit beside Dart under Internal; the dock stays at eight tools. Shortcut: N. Cut & Sew is the default.
• Draw multi-point cuts with snapping and Shift axis locking. Enter or double-click finishes; Escape cancels. Outside-to-outside lines cut only inside the pattern.
• Exactly two outline crossings are required. Invalid cuts leave the design unchanged and explain why.
• Keep fabric, mesh density, fixed pattern-space UVs, existing outer-edge sewing and arranged placement. Cut & Sew adds a removable seam. Undo and redo cover the complete operation.

Live panels and optional avatar arrangement

• Closed patterns immediately create flat 3D panels that follow committed outline edits and 2D moves.
• Avatar-owned bounding volumes and editable arrangement points support click-to-wrap placement, tangent-flat arrangement, spiral wrapping and relative G/R adjustments. H toggles the points with the body guide.
• Reset to 2D layout clears arrangement without changing patterns or UVs. Regular simulation reset preserves arrangement.
• Save/load and garment-library refit preserve point-relative arrangements. Missing points fall back to 2D layout with a status message. Starters use explicit arrangement points.
• Older design versions retain legacy placement. Cloth setup, meshing and sewing-spring algorithms remain protected and regression-tested.

Scope and limitations

Anatomy detection is heuristic, with fallback cylinders for absent sections. Wrapping uses a cylindrical radius at the chosen point height, not fitted body-surface placement; tall pieces can intersect wider neighboring sections. This is an editable starting placement, not automatic fitting or full Marvelous Designer parity.

Verified build

Source: 3fb1ffb (PR #18; feature batch PR #17).
All nine automated suites, five native Blender GUI runs, Blender extension validation, Rule Zero token/AST checks, dead-code/unused-import checks and publication checks pass. Tested in Blender 5.2.3 LTS; requires Blender 5.2+.

Devil Designer 0.7.0 - Curve Drafting & Multi-Selection Transforms

Devil Designer 0.7.0

Direct Curve Drafting & Curve Editing

• Direct Curve Drawing: With the Polygon tool, a click places a Corner point and click-and-drag creates a Smooth point while pulling collinear handles out live. Includes Shift (15-degree steps) and Ctrl (grid-snap) angle/position constraints.
• Point Types:
  • Corner: Sharp angles; incoming and outgoing handles move independently.
  • Smooth: Collinear handles maintain aligned tangents with independent lengths.
  • Auto: Dynamic tangents automatically computed from neighboring points, updating live as neighbors move.
  • Quick-cycle point types of all selected points with shortcut C or select directly from right-click contextual menu. Status bar indicates selected point type(s).
• Edge Bending: Drag the middle of any straight or curved edge to bend it directly through the cursor without affecting neighboring edges.
• Double-Click Edge Split: Double-clicking an edge adds a point at the exact click location without altering curve geometry; Q splits at the 0.5 midpoint.
• Selective Handle Visibility: Handles only display for selected points or endpoints of selected edges, eliminating canvas clutter.
• Legacy Migration: Previous designs migrate seamlessly with exact geometric and topological parity (points with handles migrate to Smooth, points without to Corner).

Multi-Selection & Group Transforms

• Multi-piece and multi-point marquee box selection and Shift+click toggling.
• Unified group translation, horizontal/vertical flipping, and 90-degree clockwise/counter-clockwise rotation preserving internal shapes and seam relationships.

Validation & Quality

• All test suites passing, including headless unit tests, regression tests, and in-engine Blender 5.2.3 LTS GUI suites.
• Validated extension package against Blender add-on standards.

Installation

Requires Blender 5.2+. Tested in Blender 5.2.3 LTS.
