Load, create, save, export, and validate outdoor maps.

• Load maps from setting.txt Scan your client’s outdoor map list and open any map from setting.txt in one workflow.
• Create new maps Wizard with Flat, Dungeon, Farm Map, Normal Map, or Custom templates. Preset sizes from 1×1 to 4×4, or custom up to 16×16.
• Texture sets & environment Create or reuse texture sets, pick an environment, and optionally generate border cliffs for new maps.
• Save map data Set the assets folder, then save terrain, objects, NPC spawns, environment (.msenv), server attributes, atlas, and per-tile minimaps.
• Export & legacy shadows Export full map packages for deployment. Generate legacy shadowmaps for the current map from the File menu.
• Map validation Run checks for common map issues and see errors or warnings before you ship to players.

DX11 preview, overlays, minimap teleport, and render settings.

• DX11 viewport Real-time preview with terrain, water, skybox, buildings, trees, effects, shadows, and NPC models — the same view you edit in.
• Visibility & overlays Toggle wireframe (F3), fog, objects, water, effects, shadows, markers, NPCs, and Block/Water/BanPK attribute overlay (F2).
• Mini-atlas teleport Optional mini atlas overlay: click a tile to move the camera there instantly while editing large maps.
• Status HUD On-screen FPS, frame time, camera position, and the active tool so you always know what mode you are in.
• Render options VSync, FPS limit, MSAA level, shadow mode (modern vs legacy), and modern shadow map resolution.

Sculpting, texture paint, water, and attribute layers.

• Terrain sculpting Alt+1 raise, Alt+2 lower, Alt+3 smooth, Alt+4 flatten. Circle or square brush with adjustable radius and strength.
• Height tools Raise, Lower, Smooth, Flatten, Plateau, Terrace, and Erosion. Marker polygon mode can limit brush edits to a marked region.
• Perlin noise terrain Procedural height with seed, amplitude, frequency, octaves, lacunarity, persistence, and base height for quick landforms.
• Texture painting Paint layers from the active texture set. Texture mix, source filters, Replace Entire Map, and palette slots 1–8 (Ctrl+LMB eyedrop, Shift+1–8 store).
• Water & attributes Place or remove water and set water height. Paint Block, Water, and BanPK attributes; eraser mode; stamp block under all trees or around a selected object.

Objects, trees, NPC spawns, and regen files.

• Asset browser Categories, text filter, grid/list view, thumbnails, and drag-drop placement for buildings, trees, effects, and dungeon blocks.
• Transform & clipboard Select, move, rotate, copy, paste, delete, snap to terrain or grid. Double-click opens the edit popup for objects or NPCs.
• Multi-select & scatter Box select (Alt+LMB), same-type map-wide select (Ctrl+Alt+LMB), batch delete/yaw/height, object eraser radius, and object scatter with density and spacing.
• Tree tools Tree Randomizer swaps trees from an SPT pool (all or selection). Map Tree Groups select, isolate, or delete every tree with the same SPT path.
• Server map & mob data Point the editor at your server map folder. Load NPC spawns from npc.txt; mob names and VNUM→model from mob_names, mob_proto, or npclist.
• NPC placement & regen Place NPCs by VNUM, edit direction/span/respawn/count/percent, regen editor (regen.txt, boss.txt, stone.txt, group.txt). 3D spawn markers in the viewport.

Sun, fog, .msenv, atlas export, undo, and diagnostics.

• Sun & time of day Sun path with fixed time, clock display, path reversal, and quick presets — similar to client Dynamic Sky behaviour.
• Lighting, fog & water Ambient/diffuse, fog, wind, sky and cloud colours, water colours, wave strength, and camera speed. Save changes to .msenv.
• Atlas & minimap Top-down atlas preview with accept/reject, export atlas.dds, atlas.sub, and minimap.dds per tile. Optional auto-atlas on save.
• Legacy shadowmaps Generate legacy shadowmaps for the current map (File → Generate Legacy Shadowmaps) for older client pipelines.
• Undo, redo & log Unified undo/redo for objects, NPCs, and terrain brush strokes (Ctrl+Z / Ctrl+Y). History in the Edit menu; log panel for save/load and diagnostics.

Textures+ / PBR, grass, and per-object scale (integration).

• Textures+ / PBR preview Client PBR Normal and height maps with parallax (POM) and procedural specular in the viewport. Your game client must already support PBR in-game.
• Generate & regenerate maps Client PBR Options → Terrain → Textures+: auto-generate missing _n/_height maps from diffuse, regenerate per texture, BC4/BC5 export. Batch tool: generate_terrain_normals.py.
• Grass system Source Terrain grass masks, procedural placement, billboards, and custom grass assets. Requires merging grass code into your client source.
• Object scaling Source editor_object_scale.txt drives per-model scale in-game. Requires client source integration; optional paid install available.

FBX import, UI languages, ImGUI on DX8/9/11+.

• FBX import Import FBX meshes into the editor workflow — not limited to classic OBJ/GR2 pipelines alone.
• 9 UI languages German, English, Hungarian, Romanian, Turkish, Polish, Spanish, Italian, and French in the editor UI (Options → Language).
• ImGUI · DX8 / DX9 / DX11+ Modern ImGUI interface. Licensed builds target DX8, DX9, and DX11+ Metin2 clients from one editor package.
