SAM'S FORGE

PROCEDURAL ENVIRONMENT AUTHORING SUITE
SUBSTRATA-READY WORLD AUTHORING

BUILD THE WORLD.
SKIP THE BLENDER DETOUR.

A fast browser-based toolkit for creators who want editable structures, procedural materials, sculpted terrain, clean GLB output, float32 EXR heightfields, and RGB material masks without learning a full 3D production suite.

01 · ARCHITECTURE

Structure Builder

Draw architectural forms directly and export editable, game-ready structures without entering a full modeling application.

  • Walls, arcs, vaults, domes, floors, ceilings, and roofs
  • Door and window openings
  • Whole-object and individual-surface material assignment
  • AI-readable project JSON and GLB export
02 · SURFACES

Material Lab

Create procedural PBR materials independently, preview all generated maps, and add them to the project material library.

  • Concrete, wood, clay, metal, stone, and plaster presets
  • Base color, normal, ORM, and height maps
  • Live 3D preview and editable material recipes
  • Texture-map ZIP export
03 · OBJECTS

Prop Generator

Create dimensionally editable furniture, doors, and windows from practical presets, then export named GLB parts.

  • Couches, chairs, tables, desks, and beds
  • Doors with frames, panels, glass inserts, and handles
  • Windows with frames, mullions, glass, and sills
  • Shared project material import and editable JSON
04 · LANDSCAPE

Terrain Sculpt + Mask Painter

Start with an island, archipelago, square, or empty ocean and draw the actual elevation field instead of relying on image interpretation.

  • Connected mountain-range strokes
  • Lowlands, beaches, rivers, valleys, smoothing, and sea carving
  • Automatic RGB mask generation with manual paint overrides
  • Substrata-ready float32 EXR export
