Lodestone

Edit the world
without guessing.

Terrain, objects, collision, spawns, effects and dungeons — read and written in the client’s own formats, byte for byte. A DirectX 11 viewport that draws what the game draws, and a performance readout that tells you when a map has grown past what the game can carry.

What it does

Terrain

Height, texture painting and vertex colour, with a brush that keeps working across patch borders instead of stopping at the seam.

Objects

Place and edit with a full gizmo — move, rotate, scale — with multi-select, pivots and a four-view split.

Collision & regions

KSM collision, region and portal editing, read from the same files the server uses.

Spawns & NPCs

Monster zones and NPC placement, with positions picked straight off the terrain.

Models & effects

GB models with the client’s own material and blending rules, skinned animation, and the full particle system.

Dungeons

Read, edit and save .map dungeons — structure, props and lights — with a byte-identical round trip when nothing is changed.

Integrity

CRC and hash checks across a whole client, so a broken file is found before the game finds it.

Performance readout

An estimate of what the GAME will manage with your map, not what this editor manages. They are not the same number.

What it is not

Lodestone edits the files a client and server already use. It is not a game engine, it does not run a server, and it will not turn one game into a different game. If you need to change what a map looks like, this is the tool. If you need to change how the game works, it is not.

It also deliberately stays close to what the original client can draw. An editor that renders far better than the game lets you build maps the game cannot handle — so the performance readout is measured against the game, not against this machine.

A seat is one machine, and you can release one yourself from your account — changing or reinstalling a PC needs no contact with us. When a licence expires the editor keeps opening and viewing your work; saving stops. Nothing you made is locked away.
