WebGL map editor · Ragnarok Online

Build entire Ragnarok maps
without leaving one window.

Paint terrain and textures, sculpt height, bake real lighting, drop in RSM 2.3 models, draw walkability and export the minimap — all in a fast browser-native editor that saves everything encrypted and updates itself.

Everything in the box

One editor for the whole map, from the ground plane up to the lighting pass.

Terrain & texturing

  • Texture painting that centres on the exact pointer, at 1×, 2×, 4×, 8× and any brush
  • Overpaint compositing — blend a second texture over the ground with coverage and smoothing
  • Height sculpting, per-vertex colour and multi-plane water
  • Walls, with height picked straight from the terrain

Lighting that bakes itself

  • Place point lights and a global sun; the GND lightmap bakes on every save
  • Ambient, directional diffuse and coloured point light, combined per cell
  • Live preview in the viewport — see the light while you move it
  • Import and export lightmaps as BMP

Models & objects

  • RSM 1.x and RSM 2.2 / 2.3 — the newest client models load and render
  • Overpaint works on model textures too
  • Objects, effects and sounds — with a spatial audio preview you can walk past
  • Import your own meshes and convert them in place

Walkability & minimaps

  • Paint the GAT walkability grid, or generate a maze, indoor, field or dungeon layout
  • Export a two-colour walkability map — grey walkable, black blocked
  • Render a top-down colour minimap at any resolution
  • Get-in-game-position tool — click a cell, read its coordinate, place NPCs without /where

Workflow

  • GRF Manager — stack GRFs and RO folders, reorder them, load order persists
  • Undo / redo, copy / paste regions
  • Every project setting is saved encrypted and read back the same way
  • Tabs remember what's unsaved; the editor saves in the background

Under the hood

  • A native C++ core with a WebGL viewport — fast on real maps
  • End-to-end encryption for configs, patches and containers (libsodium)
  • Licensed and auto-updating — the launcher patches the editor for you
  • GRF-native, up to 1 GB maps

Latest news

What shipped recently, straight from the changelog.

r3260

RSM 2.3 models & overpaint

The newest kRO model format now loads, renders and can be re-textured with overpaint. A separate RSM2 browser opens on a double-tap of M or O.

r3262

Minimaps, straight to BMP

Export a sharp two-colour walkability map or a top-down colour minimap to Output/Minimaps, with a preview before it lands on disk.

r3256

GRF Manager

Add as many GRFs and RO folders as you like, reorder them by drag or arrow, and the load order sticks across restarts.
