v1.0.4 — Changelog

Performance

• Batch auto-group creation — Eliminated per-group edit↔object mode switches in Phase 3; sharp edges, UV seams, and smooth/flat shading are now collected across all groups and applied in single batched passes
• Direct BMesh writes — Replaced bpy.ops.mesh.mark_sharp() / bpy.ops.mesh.mark_seam() operator calls with direct edge.smooth / edge.seam assignments, removing selection save/restore overhead
• Bypassed update callbacks during batch creation — CREASE, BEVEL, SMOOTHING_GROUP, and UV_SEAMS properties use id-property syntax (group["prop"]) to skip expensive per-group callbacks
• Suppressed per-group color updates — Added batch_color_suppress flag to defer update_vertex_colors() during batch creation (was firing ~40 times for 20 groups), with a single finalization pass at the end
• GPU batch caching for color overlays — _rebuild_overlay_cache() now pre-computes world-space triangles and builds GPU batches once on dirty flag; draw_colored_elements() no longer creates a BMesh or recomputes geometry every frame

Features

• Max groups per auto-run — Added max_groups property (default: 20) to cap group creation; when exceeded, islands are sorted by size (largest first) and only the top N are processed

Bug Fixes

• Fixed crash: TypeError: unsubscriptable object — mesh.smart_groups.add() inside create_new_group()

Smoothing Groups v1.0.2 — Changelog

Bug Fixes

• Fixed a crash when adding a new selection to an existing Bevel Weight group
• Fixed bevel weights not updating on the mesh after internal changes
• Fixed errors on startup with Blender 5.0

Readable Layer Names

• Group data in Blender's attribute browser now shows the group name instead of a long random ID
• Example: sg_Bevel_Weight_01_a8f3b2c1 instead of smart_group_40b4a7c6-7a87-4177-...
• Renaming a group automatically updates its attribute names
• Existing projects are migrated automatically — no manual steps needed

Per-Group Bevel Modifiers (New)

• You can now give each bevel group its own independent Bevel modifier
• Enable the checkbox next to any bevel group in the Modifier Manager panel
• Each modifier has fully independent settings: width, segments, profile, miter, normals — everything
• Groups with individual modifiers are completely isolated from each other
• Disabling the toggle removes the modifier cleanly

Modifier Manager Improvements

• The panel now shows a Global Bevel section (shared by all groups without individual modifiers) and separate sections for each bevel group
• All Bevel modifier properties are now exposed in the UI, including:
  • Custom profile curves
  • Miter inner/outer settings
  • Face strength mode
  • Material offset
  • Intersection method
  • Edit mode & On Cage visibility toggles

Bug Fixes

• Fixed crash (EXCEPTION_ACCESS_VIOLATION) when toggling edit mode with color overlay enabled — stale BMesh reference stored in overlay cache caused use-after-free during draw callback
