- Rotate 90 CW button in Mirror/Rotate section
- Snapshots outer vertex heights into 129x129 grid, rotates in-place,
writes back with inner vertices averaged from surrounding outers
- Useful for reorienting terrain features or creating rotational
symmetry (rotate + mirror for 4-way symmetric arenas)
- Detail Noise: adds high-frequency roughness to existing terrain
without destroying the overall shape (amplitude 0.5-10, freq 0.01-0.5)
- Useful after smooth/generate to break up unnaturally smooth surfaces
- Workflow: generate → smooth → detail noise for natural look
- Separate seed from main noise generator for independent control
- Edge Ramp: smoothly transitions tile borders to a target height
so adjacent tiles can connect seamlessly
- Configurable target height and ramp width (how far in from the edge)
- Quadratic blend for smooth start from edge → interior
- Essential for multi-tile zone creation: ramp each tile's edges to
match its neighbor's border height
- Smooth Beaches button in Water panel: creates gentle beach slopes
near water level by blending terrain toward waterline height
- Configurable beach width (15 units default)
- Quadratic falloff creates natural concave beach profile
- Use after filling water to soften harsh land-water edges
- Workflow: sculpt → fill water → smooth beaches → paint sand
- Voronoi noise generator: creates cell-like terrain patterns with
ridge features at cell boundaries (F2-F1 distance field)
- Configurable cell count (5-100) and amplitude
- Toggle between Value noise and Voronoi in the noise generator section
- Creates interesting mesa/plateau formations and organic shapes
- Random cell centers with per-cell height variation
- Offset Heights: shifts all terrain heights by a constant amount
(-100 to +100 range with Apply button)
- Useful for raising terrain above water level or sinking below
- Slider + Apply button in the Noise Generator section
- Invert Heights: flips terrain upside-down around midpoint (mountains
become valleys and vice versa)
- Fill Entire Tile with Water: one-click fills all 256 chunks at the
configured water height and liquid type
- Remove ALL Water: clears water from every chunk instantly
- Water panel now has three water operations: fill tile, remove under
brush, remove all
- fillWater() and invertHeights() methods on TerrainEditor

- Quadratic falloff at edges for smooth cliff walls
- Random seed button for quick shape exploration
- Fill with Water mode for instant river canyon
- Island Generator: creates raised center terrain dropping to edges
with configurable center height and edge drop depth

- Add water around the island for instant ocean environment
- Workflow: New Terrain → Island → Noise → Smooth → Auto-paint
- Ridge Generator: creates mountain ranges by setting start and end
points, with configurable width and height
- Cross-section uses quadratic falloff, along-axis uses sqrt taper
for natural mountain range silhouette (wider at center, tapering
at both ends)
- Same start/end workflow as river/road tools
- Hill Generator: creates smooth bell-curve hills at cursor position
with configurable radius and height
- Valley mode: same shape inverted, creates natural depressions
- Uses (1-t^2)^2 falloff for very smooth natural-looking slopes
- Two buttons: "Create Hill" and "Create Valley" for quick terrain
shaping without switching brush modes
- NPC markers now render with NO depth test (via gizmo pipeline) so
they're always visible even on sloped/rough terrain
- Mesa/Plateau generator: creates raised flat areas with steep cliff
edges — configurable radius, height, and edge steepness
- NPC markers drawn after gizmo in the render pipeline to guarantee
they appear on top of everything
- Fixes NPC visibility on non-flat terrain
- Crater Generator in Sculpt panel: creates a bowl-shaped depression
with configurable radius, depth, and raised rim height
- Parabolic bowl interior with sinusoidal rim and smooth outer falloff
- Perfect for creating lakes (fill with Water mode), arenas, or
impact craters for volcanic zones
- One click at cursor position, uses brush position for center
- "Reset to Flat" button in Noise Generator section: zeroes all heights
across entire tile for starting over without creating a new terrain
- Useful workflow: reset → noise → smooth → scale → clamp → auto-paint
- River/Road Carver section now has two modes:
- River: carves a channel below terrain (existing)
- Road: flattens terrain to interpolated height between start/end
- Road mode smoothly transitions height along the path with quadratic
falloff at edges for natural embankment shape
- Set Start → Set End + Apply workflow works for both modes
- Roads follow terrain slope by interpolating between start/end heights

position, storing relative offsets from center
- Paste Stamp: applies the copied height pattern at a new location,
finding nearest vertices and setting their heights
- Stamp status shown in panel ("Stamp ready" / "No stamp copied")
- Auto-stitches chunk edges after paste for seamless results
- Useful for replicating hills, craters, or other terrain features
- Clamp Heights: sets min/max height bounds across entire tile
(DragFloatRange2 slider for min/max, -500 to 2000 range)
- Useful workflow: Generate noise → Smooth → Clamp to desired range
- Prevents terrain from going underground or too high
- All affected chunks marked dirty for mesh regeneration
- Smooth Entire Tile: global smoothing pass with configurable iterations
(1-10). Smooths across chunk boundaries for seamless results. Updates
inner vertices from smoothed outer grid. Great after noise generation.
- Snap to Ground checkbox: on by default, objects placed at terrain
surface. Disable for floating/airborne objects.
- Random Rotation + Snap Ground checkboxes side-by-side for fast setup
- Toast notifications on noise apply and smooth operations
- Smooth pass uses cross-chunk neighbor averaging for edge continuity
- Export Heightmap: File > Export Heightmap saves terrain as 16-bit
RAW grayscale (129x129) for use in external terrain editors or
as a backup. Configurable max height scale.
- Help overlay (F1 or Help menu): lists all keyboard shortcuts
organized by category (navigation, editing, object transform, view)

with configurable frequency, amplitude, octaves, and seed
to create hills/valleys across entire tile instantly
- Sky/Lighting presets: View > Sky menu with Day (blue sky, high sun),
Dusk (orange, low sun), Night (dark blue, moonlight)
- Viewport clear color and light direction now configurable at runtime
- Noise uses smoothstep interpolation with octave fractal layering
- Punch Hole / Fill Hole buttons in Sculpt panel: creates terrain
holes (4x4 bitmask) for cave entrances, mine shafts, etc.
Uses brush radius to determine affected area.
- Recent Textures: paint panel shows last 6 used textures as quick-
select buttons (no need to re-search the full list)
- Holes saved in ADT format (MCNK holes field) and respected by
the mesh generator (triangles skipped at hole positions)
- Terrain normals recalculated after height changes (smooth lighting
on sculpted terrain instead of flat-shaded appearance)
- Ghost preview and brush indicator cleared when switching modes
(prevents stale model instances or circles persisting)
- File > Clear All resets undo history and selections
- Normal computation uses finite differences from neighbor heights,
handles both outer (9x9) and inner (8x8) vertex grid positions
Standalone wowee_editor tool for creating custom WoW zones.
This is a rough initial implementation — many features work but
M2/WMO rendering still has issues (frame sync, texture layout
transitions) and needs further polish.
Terrain:
- Create new blank terrain with 10 biome types (Grassland, Forest,
Jungle, Desert, Barrens, Snow, Swamp, Rocky, Beach, Volcanic)
- Load existing ADT tiles from extracted game data
- Sculpt brushes: Raise, Lower, Smooth, Flatten, Level
- Chunk edge stitching prevents seams between tiles
- Undo/redo (100-deep stack, Ctrl+Z/Ctrl+Shift+Z)
- Save to WoW ADT/WDT format
Texture Painting:
- Paint/Erase/Replace Base modes
- Full tileset texture browser (1285 textures from manifest)
- Per-zone directory filtering and search
- Alpha map editing with 4-layer limit (auto-replaces weakest)
Object Placement:
- M2 and WMO model placement with full manifest browser (11k M2s, 2k WMOs)
- M2Renderer + WMORenderer integrated (loads .skin files for WotLK)
- Ghost preview follows cursor before placing
- Ctrl+click selection, right-click context menu
- Transform gizmo (Move/Rotate/Scale with axis constraints)
- Position/rotation/scale editing in properties panel
NPC/Monster System:
- 631 creature presets scanned from manifest, categorized
(Critters, Beasts, Humanoids, Undead, Demons, etc.)
- Stats editor: level, health, mana, damage, armor, faction
- Behavior: Stationary, Patrol, Wander, Scripted
- Aggro/leash radius, respawn time, flags (hostile/vendor/etc.)
- Save creature spawns to JSON
Water:
- Place water at configurable height per chunk
- Liquid types: Water, Ocean, Magma, Slime
- Rendered as translucent colored quads
- Saved in ADT MH2O format
Infrastructure:
- Free-fly camera (WASD/QE, right-drag look, scroll speed)
- 5-mode toolbar: Sculpt | Paint | Objects | Water | NPCs
- Asset browser indexes full manifest on startup
- Editor water/marker shaders (pos+color vertex format)
- forceNoCull added to M2Renderer for editor use
- AssetManifest::getEntries() and AssetManager::getManifest() exposed
Known issues:
- M2/WMO rendering may not display on first placement (frame index
sync between update/render was misaligned — now fixed but untested
end-to-end)
- Validation layer errors on shutdown (resource cleanup ordering)
- Object placement on steep terrain can miss raycast
- No undo for texture painting or object placement yet
