- 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
- Canyon Generator: carves a winding canyon across the entire tile
using layered sine waves for natural serpentine shape
- Configurable width, depth, and seed for different canyon shapes
- 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
- Flat interior plateau → gradual beach slope → steep underwater drop
- Preserves existing noise detail at 30% blend for natural variation
- Add water around the island for instant ocean environment
- Workflow: New Terrain → Island → Noise → Smooth → Auto-paint
- File > Generate Complete Zone: runs the full procedural pipeline
in one click: noise → smooth (3 passes) → recalc normals →
height-based auto-paint (sand/grass/rock/snow) → slope-based
cliff paint (rock on steep faces)
- Creates a fully textured, natural-looking zone from flat terrain
- Removed stale quickGenerate checkbox from New Terrain dialog
- Auto-Paint by Slope: paints rock texture on steep terrain surfaces
with configurable slope threshold (0.1 - 0.9)
- Uses per-vertex normal Z component to detect steepness
- Alpha blending based on slope gradient for smooth transitions
- Workflow: sculpt terrain → recalc normals → auto-paint slope → rock
appears naturally on cliffs while flat areas keep their biome texture
- Creature names rendered as screen-space text above each NPC marker
- Red text for hostile, green for friendly
- Labels project from 3D world position to screen coordinates
- Only visible when NPC is in front of camera (clip.w > 0)
- Much easier to identify placed creatures at a glance
- NPC placement now only updates cheap marker geometry (no M2 reload)
- Full M2 rebuild only triggers when PLACED OBJECT count changes
(not NPC count — NPCs use markers, not M2 instances for now)
- Split lastObjectCount_ into lastObjCount_ + lastNpcCount_ to track
objects and NPCs independently
- Prevents the destructive clear+reload cycle that caused GPU crashes
when rapidly placing multiple NPCs
- Filter known effect/particle models from NPC presets (alliancebomb,
blackhole, etc.) that cause vertex explosions — these are particle
effect models misclassified as creatures
- "Find Tile" button now shows toast when no ADT exists for a map
- Vertex validation catches NaN/infinite/extreme positions before GPU
- These models are now skipped entirely from the creature browser
Root cause of GPU crashes (VK_ERROR_DEVICE_LOST): every NPC placement
triggered a full clear+reload of ALL M2 models. After several cycles
the GPU state corrupted, causing vertex explosions and device lost.
Fixes:
- NPC placement now only updates cheap marker geometry (no M2 reload)
- Full M2 rebuild only happens when object COUNT changes (not every click)
- clearAllObjects() properly resets viewport, placer, spawner, markers,
and history in one call with vkDeviceWaitIdle fence
- New Terrain uses clearAllObjects() for consistent reset
- Clear All menu item calls clearAllObjects()
- M2 vertex validation: rejects models with NaN/infinite/extreme
vertex positions before GPU upload (prevents vertex explosions)
- NPC marker building extracted to updateNpcMarkers() method
(can be called independently without M2 rebuild)
- 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
- Middle mouse drag orbits camera around the terrain point under cursor
(or 100 units ahead if no terrain hit)
- Maintains distance from pivot while rotating yaw/pitch
- Much more intuitive for inspecting terrain features, placed objects,
and NPC positions from different angles
- Works alongside right-drag (free look) and WASD (fly)

- Scales proportionally with terrain tile size
- Visible in all brush-based modes (Sculpt/Paint/Water)
- Helps orient where you're working relative to the full tile
- "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
- Pair with Paint mode to add cobblestone/dirt texture on the road
- "Find Valid Tile" button in Load dialog: auto-scans manifest for the
first available ADT tile of the selected map (checks center range
25-45 first for open world, then full 0-63 for dungeons)
- Fixes "wrong coords" issue — dungeons use different tile coords than
open world maps, now auto-detected
- Map name lowercased for manifest lookup consistency
- Tile check shows green "Tile found" or red "Tile not found" indicator
- NPC markers now 30 units tall with octagonal base, colored pole,
and yellow diamond at top — visible from any camera altitude
- Red pole = hostile, green pole = friendly, yellow top = all NPCs
- River/Path Carver: set start point, set end point, carves a channel
between them with configurable width and depth
- Smooth quadratic falloff at edges for natural riverbank shape
- Pair with Water mode to fill carved channels
- River Carver in Sculpt panel: carves a channel between two points
with configurable width and depth
- Set Start at cursor, then Set End + Carve to create the channel
- Smooth quadratic falloff at edges for natural riverbank shape
- Works by projecting each terrain vertex onto the line segment and
lowering height based on distance from center
- Auto-stitches chunk edges after carving
- Pair with Water mode to fill the carved channel with liquid

- Instantly flattens terrain under brush radius to cursor height
- Perfect for creating building sites, road beds, camp grounds
- Applies 30 iterations of flatten for a thorough result
- Restores previous brush mode after completion
- Quest giver and turn-in NPC now selected from a dropdown of placed
creatures instead of typing raw IDs — shows name + id for each
- Links quests directly to NPCs you've already placed on the map
- "None" option to unset NPC link
- Much more intuitive quest→NPC workflow
- Mirror X: copies left half of terrain to right half (mirrored)
- Mirror Y: copies top half to bottom half (mirrored)
- Useful for creating symmetric zones, arenas, or balanced landscapes
- Auto-stitches all chunk edges after mirror for seamless results
- UI buttons in Sculpt panel under "Mirror Terrain" section
- Auto-Paint by Height: automatically sets base texture per chunk based
on average height — configurable thresholds for sand/grass/rock/snow
- Uses Tanaris sand, Elwynn grass, Barrens rock, Dragonblight snow
- One-click to texture an entire procedurally generated terrain
- Adjustable height thresholds via drag floats
- Workflow: noise → smooth → clamp → auto-paint for instant biome
- Copy Stamp: captures all vertex heights within brush radius at cursor
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
