Build isometric worlds with tilesets and MaterialZ
New in v0.96, 2D Iso brings tile placement to an isometric grid. Import isometric tilesets or use procedural MaterialZ materials, then paint ground and place scenery with the Rect tool. Shape hills and plateaus, paint paths over the terrain, and add characters, items, and Behavior Nodes.

3D
Shape dungeons, towns, and terrain in 3D
Start with simple shapes and build your world by hand using the Object, Face, Edge, and Vertex tools. Extrude walls, cut doorways, sculpt terrain, and apply tiles or MaterialZ materials to surfaces. Place characters and items, add Behavior Nodes, and play in first person or from an isometric camera.

Text
Build text-based adventures in the same world
Draw named areas and connections on your region maps, then write descriptions for places, characters, and items in the Authoring dock. Configure player commands with Entity Nodes and create reactions with Behavior Nodes. Play through the terminal client with commands such as look, take, and talk.

General Features
Build on a shared set of creative tools and gameplay systems. Materials, painting, and terrain tools support the visual workflows; nodes, rules, authoring, and localization also carry through to text play.
Entity & Behavior Nodes
Configure characters, equipment, items, and player input with Entity Nodes. Connect events and actions in Behavior Nodes to create NPC routines, dialogue, quests, and interactions, with live feedback while your game runs.

Editable Screens & Built-in UI
Design and customize game screens with Eldiron's map tools. The built-in UI already understands inventories, equipment, spells, and character actions, drawing icons, descriptions, costs, and cooldowns from your game data and ruleset. Adjust responsive layouts and artwork, or create your own widgets.
Explore Screens & UIEditable RPG Rules
Start with the bundled fantasy ruleset for races, classes, equipment, combat, spells, and progression. Edit definitions through the Rules editor so every character and client uses the same gameplay rules.

MaterialZ Materials
Create editable procedural materials by combining shapes, noise, colors, and imported images. Layer and blend them into roads, floors, walls, and terrain, with shared palette colors and reusable recipes.
Explore MaterialZ
Terrain Tools
Raise, lower, and smooth the landscape with a brush, or draw editable guides for slopes, hills, and plateaus. Procedural ground materials and painted paths follow the terrain as you reshape it.
Explore Terrain Tools
Paint Brush
Paint moss, dirt, cracks, puddles, and other details directly onto isometric terrain or 3D surfaces. Adjust brush size, opacity, and palette colors, or scatter organic stamps such as grass, flowers, and rubble.
Explore the Paint BrushAutomatic Chunk Streaming
Build large regions without manually dividing them into separate maps. Eldiron loads nearby scene chunks, prepares surrounding chunks in the background, and unloads distant geometry as the player moves. This keeps rendering focused on the area being explored.
Explore Region StreamingSimulation Modes
Choose realtime play, turn-based steps, or a hybrid that advances on player actions and after an idle timeout. Set the pace independently of your game's camera or presentation.
Explore Game SettingsAuthoring & Text Play
Give places, connections, characters, and items names and descriptions in the Authoring dock. Use that text for looking around in graphical games or exploring the same authored world through the terminal client.
Explore AuthoringLocalization
Keep dialogue, quest text, combat feedback, and system messages in shared language tables. Reuse translated messages in rules and Behavior Nodes, with placeholders for character names, damage, and other game values.
