…lease job macOS: packaging/macos/bundle.sh signs the bundle inside-out with the Developer ID identity that import-cert.sh puts in a temporary keychain (hardened runtime, secure timestamp, empty entitlements), notarizes and staples it through the App Store Connect API key (Apple-ID fallback), and ships a drag-to-Applications disk image. Without the secrets it falls back to ad-hoc signing with a warning, as before. Windows: the archive is `redrob-shape-<version>-windows-<arch>-portable.zip`, the one zip name Redrob Launcher installs. scripts/check-asset-names.py refuses any name the launcher's parser would skip; every packaging job runs it, and the CDN job runs it over the whole set. release.yml: the CDN job publishes every artifact to cdn.redrob.ai/shape/ (versioned path read back and compared, then the latest/ alias; a missing bucket uploads nothing) and the publish job is the organization's release-publish.yml, which writes SHA256SUMS.txt and redrob-launcher.json and publishes the release as latest.
…ifier shape_ops::bevel_edges pushes every face corner inward along each of its beveled edges, inserts a corner that slid along an unbeveled edge into the face across it (no T-junctions), then adds one quad per beveled edge and one polygon per touched vertex. A strip that ends inside a face (one beveled edge at a 3-valent vertex) hands its end edge to that face instead of a flat triangle. Beveling every edge of a cube gives the 26-face chamfered cube; results are checked closed, oriented outward and Euler-consistent. UI: Edit > Mesh > Bevel All Edges, Ctrl+B modal over the selected faces' edges, Bevel modifier with an offset; agent mesh_op `bevel` and add_modifier `bevel`.
macOS Developer ID signing and notarization, launcher-readable asset names, CDN and shared publish job, bevel.
…gions, tabbed Properties) Measured against a 1280x800 Blender 5.3 window: top bar 26, header 24, right column 228 with the Outliner 208 over Properties and its 28px tab strip, status bar 20, toolbar 50; colours #181818 / #303030 / #3f3f3f / #282828 / #3d3d3d / #1d1d1d, accent #4772b3. Only tabs and workspace tabs with content are offered. New keys: T, N, Ctrl+Space, Shift+D, H, Alt+H, Alt+A, Ctrl+I. Properties moved to properties.rs, the layout to layout.rs, the theme to theme.rs.
Local gitflow rules replaced by the org caller; types come from the one org-wide list.
…pad views, Ctrl+J, P One operator registry (keymap::Op) drives F3 search, the pointer popups and the keymap table. Box select projects object origins (faces in edit mode) into the drag rectangle. Axis views go orthographic and orbiting restores perspective, as Blender does. Key matching now requires the exact modifiers: egui consume_key let plain A swallow Shift+A.
EditSelection now holds vertices, edges and faces and flushes between them as Blender does. shape-ops gains delete/dissolve, fill, merge, linked/grow/shrink and edge/face loop walks (the loop follows 4-valent vertices and goes around an n-gon cap at 3-valent ones). The GPU draws vertex dots as screen-space squares through the line pipeline. A headless wgpu test renders a frame and reads the pixels back. Key matching: 1/3 are select modes in edit mode, views in object mode; popup clicks give keyboard focus back so hotkeys keep working.
…n, Ctrl+V/E/F menus bevel_edges_segments splits every strip into n quads along a quadratic profile through the original edge and splices the rows into the vertex polygons (and into the host face when a strip ends inside one). edge_loops orders a selection into chains; bridge_edge_loops pairs two loops by nearest start and rung length and orients against existing half-edges. spin sweeps edges around an axis. knife_cut splits a face between two edge points, inserting the points into the neighbours. The viewport reports whole wheel notches to a running modal when the camera is off.
…Wireframe, Triangulate, Screw, Simple Deform, Displace, Weld Boolean is BSP clipping of the two triangle soups (volumes of two offset cubes check out: 15 / 7 / 1), stitched by position; coplanar leftovers fall back to a triangle soup. Target modifiers get the scene through evaluate_in / apply_in and read the target object base mesh in this object space. Spin now only sweeps open edges, so Screw on a closed mesh is a no-op instead of an error.
…ting, parenting, Set Origin, collections Modal::transform_with takes TransformSettings (pivot, orientation, proportional) and a camera for the View orientation; Individual Origins keeps one pivot per object. Modal::edit_transform moves, rotates or scales the selected vertices with a smooth proportional falloff computed at start and recomputed on wheel. Scene gains collections, object.collection, cursor and is_visible(), which the viewport, picking, renderer and exporters now consult.
scene::Texture holds decoded linear pixels (serde-skipped, reloaded from path on open) and samples with wrap and v-up. The GPU vertex gains a UV and a textured flag; textured triangles are grouped per texture, uploaded as Rgba8UnormSrgb and bound at group 1 (a 1x1 white texture for the rest). ShadingMode gains MaterialPreview; Solid no longer reads materials, as in Blender. The path tracer carries corner UVs per triangle and multiplies the base colour by the texture at the hit. Headless render tests cover both modes.
scene::nodes holds the NodeTree (typed sockets, one link per input, cycle check) and evaluates it into the flat Material, so the renderers stay unchanged. ui-egui::node_editor draws the canvas with the egui painter (nodes, bezier links, sockets) and places egui widgets for unlinked constants. Viewport hotkeys stand down while the pointer is over the editor, as in Blender. Shading workspace switches the viewport to Material Preview and shows the editor in place of the agent panel.
SolidOptions on ViewOptions feed a new Globals.shading vec4 and the view matrix; the shader branches on lighting (studio / procedural matcap / flat) and scales by a derivative-based cavity term. Four solid pipelines cover cull x depth-write (x-ray). Material gains viewport_color, which Solid "Material" colour shows, keeping Base Color for Material Preview as Blender does.
ops::sculpt holds the brush maths (falloff, area plane, per-brush dab, symmetry mirroring) on the half-edge mesh positions; ui-egui::sculpt_mode maps the pointer through pick_detail (or the first hit depth for Grab) into mesh space, scales the pixel radius by the hit depth, spaces dabs and records the stroke as one snapshot. Sculpt keys replace the object/modal keys while active.
ops::unwrap splits islands at seams (vertex-pair keys on MeshData), unfolds each island by rigidly placing faces across shared edges from a seed, groups faces by normal for Smart UV Project and shelf-packs island boxes into the unit square. ui-egui::uv_editor adds the U popup, Ctrl+E seam items, the UV Editing workspace and a painter-drawn UV editor.
scene::anim adds FCurve/Action/Timeline with Hermite auto-clamped Bezier evaluation and keying sets; Scene::insert_keyframe/delete_keyframe/evaluate_animation. ui-egui::timeline draws the ruler, dope-sheet rows and playhead with the egui painter, drives playback from stable_dt, and binds Blender's playback keys; object-mode I opens the Insert Keyframe popup.
scene::armature holds Bone/Armature (rest and pose matrix chains, skin matrices), VertexGroup, automatic_weights (inverse-square distance to bone segments, normalised, 10% cutoff) and skin. Modifier::Armature evaluates through evaluate_in with the armature object. ui-egui::pose_mode adds bone picking by projected segment distance, pose drags, the Ctrl+P Set Parent menu and header widgets; gpu draws octahedral bones. Outliner rows no longer indent inside a horizontal layout.
anim gains BoneLocation/BoneRotation channels evaluated into bone poses; Pose Mode I keys the selected bones. ui-egui::bone_edit adds Edit Mode for armatures (pick, E, G, X, A) over the rest bones (Armature.edit_rest). Picks tolerate the octahedron width. Tab moves Pose -> Edit. A status trace env var makes on-screen driving verifiable.
ViewOptions.weight_paint names the object and group whose weights colour the frame's vertices (gpu::weight_color ramp); ui-egui::weight_paint paints through pick_detail on the evaluated mesh with the sculpt falloff and records one snapshot per stroke.
RenderCamera gets a thin lens (with_dof from f-stop + 36 mm sensor), Renderer samples it; a noise-adaptive bilateral denoiser runs on the final linear frame when Settings.denoise is set, with PSNR tests against a 256-spp reference. RenderPanel renders animations frame by frame to PNGs and scales output by Resolution %. Camera DOF props and output fields in the properties tabs.
…mesh scene::curve holds splines of Bezier points with Blender's handle types, evaluation and a parallel-transport tube sweep; evaluated_mesh serves the tube to viewport/export. ui-egui::curve_edit adds the edit mode (pick, G, E, X, V, A) and the Data tab. Tab focus is returned to the viewport at the end of the frame so hotkeys survive mode toggles.
ops::text parses the bundled UFL font with ttf-parser, flattens outlines and ear-clips glyphs with holes, extruding with walls wound against the cap boundary; ops::metaball polygonises a Wyvill field with Kuhn marching tetrahedra and a consistent-orientation pass. Scene stores Text/Metaball data plus a cached MeshId regenerated on edit; UI adds the Add entries, Data panels and conversion.
format::interchange shares the export records and the Z-up/Y-up basis change; collada.rs builds a small DOM with quick-xml and reads polylist/triangles/polygons with input offsets; usd.rs parses nested def blocks and xformOps; fbx.rs parses the generic ASCII node tree and rebuilds Geometry/Model/Material through OO connections. Alembic is recorded as deferred.
scene::geonodes holds the tree (links replace inputs, cycles refused); ops::geonodes evaluates it by pulling from Group Output with per-node caching; a Geometry Nodes workspace adds a canvas editor. scene::compositor + render::composite apply Blur/Bright-Contrast/Glare/Gamma/HSV/Mix/Invert to the render window image and animation frames, edited in the Render window.
agent::script runs line-per-tool-call scripts over the agent tools; ui-egui prefs.rs holds the Preferences window (Interface / Keymap / Add-ons) saved under the config dir, with object-mode hotkeys read through Prefs; console.rs adds the Scripting workspace. Add-ons are *.shape files with header comments, toggled in Preferences and exposed under the Scripts menu.
Collada raw-string delimiter, quick-xml normalized_value, geonodes BooleanOp conversion, composite as_chunks, render_panel borrow, serde dep for prefs, geonodes remove_node test.
CHANGELOG 0.4.0 section, workspace version bump, Preferences window centred and non-collapsible, kittest coverage for Preferences / Geometry Nodes / Scripting workspaces.
