Lodestone
⚡ DirectX 11 renderer

The complete game editor

Terrain, objects, collision, dungeons, NPCs and the client’s own UI — drawn the way the game draws them, so what you build is exactly what players see.

🌐

True-to-game view

A DX11 renderer that matches the client — models, water, fog and NPCs shown right on the terrain.

🧱

Collision & dungeons

Paint, erase and auto-generate KSM collision for worlds and dungeons, with full undo.

👁️

NPCs, spawns & UI screens

Monster zones drawn on the terrain, NPCs placed from the camera, and the client’s own UI windows opened and edited.

🌊

Water that behaves like water

Refraction, depth and reflection — shallows show the ground through them and the surface reflects the shore.

🖥️

Multi-client / server

Several clients auto-detected; switch between them in a single click.

Everything it does

🌍

Open & navigate

  • Open a whole world, a single patch, or a patch and its neighbours — with a Recent list
  • Reads the latest maps & textures — newer GTX/DDS textures and map versions, preview / read-only
  • Multi-client / server — manage several clients, auto-detected, switch in a click
  • Click the minimap to fly the camera anywhere · reset-camera framing · four-view split (Top/Front/Side) · view-cube
⛰️

Build

  • Sculpt terrain height · paint & blend textures (export to PNG) · vertex colour
  • Decorations & grass
  • Objects (OPL) — place, multi-select (Ctrl+click), move / rotate / scale with a gizmo, duplicate, copy, paste-at-cursor, bulk-delete, full layer control
  • Object list — every object in the patch as a list, so you can reach the ones a click cannot: buried inside a building, behind a hill, stacked, or collision-only and invisible
🧱

Collision & dungeons

  • Server collision (KSM): paint, erase, auto-generate walkable, full undo — worlds and dungeons
  • Dungeon loader — open any dungeon .map and paint its collision
👾

Server content — NPCs & spawns

  • Reads your SERVER’s own data, not just the client — and writes it back
  • Spawn zones drawn by dragging on the terrain — set what spawns, how many and how often, then save it to the server’s monster table
  • NPC list and editor — place one from wherever the camera is, saved into the server’s NPC table
  • Every write keeps the original as a .bak, and undo works across it
👁️

See it like the game

  • Show models, fog — and NPCs right on the terrain
  • Water with refraction, depth and reflection, at three detail levels
  • Click any NPC → the UI previewer opens straight on its screen
  • The client's own mouse cursors · wireframe · texture-hide
🧰

Tools

  • Minimap — generate it, export to GTX or PNG, click-to-fly
  • GB model viewer — inspect any .gb model
  • PK archive browser — open & explore client .pk archives
  • Effect previewer — play an Fx / sprite effect with its model, particle and sound parts together
  • UI screens — full control of the client's HyperText interface: open a window, move and delete its controls, add buttons, labels and text lines, pick their images, or build a new window from nothing — then save it back into the archive
🩹

Repair

  • Checks a client’s models for stale CRCs and repairs them — the mismatch that makes a model fail to load
  • Checksum and manifest checks across a whole client, from the command line, so it can run as a build step
💾

Never lose work

  • Auto-backup — every save keeps the original as a .bak
  • Undo/redo everywhere · Save Patch · Save Touched · Save All Touched
⚙️

Quality of life

  • Low / Medium / High detail, chosen from your GPU the first time it starts — and changed whenever you like
  • Dark mode · live FPS + target-FPS cap · in-app update check
  • "Problems this session" — everything that went wrong while you worked, in one place, and one click to report it
  • Keyboard & mouse reference, in the app
