Procedural materials; an open-source, node-based material designer, built in pure Rust.
Build tileable PBR materials from noises, patterns and filters in a node graph, watch them update live in 2D and on a 3D model, and export the maps for any engine. It runs natively on macOS, Windows, Linux and FreeBSD, and in the browser via WebAssembly. Built by the ArtCraft team.

Note
ArtCraft is a community of artists from all walks of life. Painters, sculptors, game artists, material and texture artists, photographers, filmmakers, illustrators, designers, hobbyists, and people who picked up a stylus last week. If you make things, you belong here. Come say hi on Discord.
A look around · Made in MaterialCraft · Why MaterialCraft · Quick start · Status · Downloads · The Crafting Apps · License
Wood planks: anisotropic grain, warped and laid over planks |
Lava rock: cracked plates over glowing emissive seams |
New graph: start from a PBR template or a sample material |
Mossy ground: stones and dirt height-blended, with moss in the gaps |
Every material below is a node graph that ships with MaterialCraft as a template, built only from
its own procedural nodes (no photos, scans or textures from anywhere else) and rendered by
materialcraft-cli render --scene sphere --full --hq (the height output displaces the mesh, with
ray-traced ambient occlusion and a shadowed key light).

- Familiar. The layout, panels, menus and gestures material artists already know: a package explorer, a library of nodes with previews, the node graph with live thumbnails, a 3D view, a 2D view and a properties panel with base and specific parameters. Space opens the node search.
- Fast. Every node cooks on every CPU core, and a content-addressed cache means an edit re-cooks only what lies downstream: the brick wall sample cooks in about 40 ms at preview size. Cooking runs on a worker thread, so the UI never waits.
- Tileable by design. Noises and patterns live on whole-number lattices, so everything tiles seamlessly at any resolution, from 16 px to 8K.
- Robust. No panics in shipped code, every command tested with hostile input, every node cooked
with odd inputs in tests, unlimited undo from snapshots, and lossless
.mcraftpackages. - Open. Export base color, normal, roughness, metallic, height and ambient occlusion as PNG, JPEG, TGA, TIFF, BMP, WEBP, EXR or HDR at 8, 16 or 32 bits, with your own file name pattern.
- Works with TextureCraft. File ▸ Send to TextureCraft puts a material on TextureCraft's
shelf as a portable
.mcmat; painted onto a mesh there, its graph inputs stay live sliders and colors, re-cooked by MaterialCraft at the texture set's resolution with the mesh's baked maps feeding the graph's input nodes. - Agent-native. Every menu item and edit is a command you can drive from the CLI, a JSON control channel (including synthetic mouse and keyboard input) or an MCP server, so Claude and other agents can build materials the way a person does.
- Everywhere. One codebase for the desktop apps and the same UI in the browser.
git clone https://github.com/storytold/materialcraft
cd materialcraft
cargo run --release -p materialcraft # desktop app (opens the brick wall sample)
cargo run --release -p materialcraft -- package.mcraft # open a package
cargo run --release -p materialcraft -- --control 7878 # + JSON control channel

cargo run --release -p materialcraft-cli -- new wood wood.mcraft
cargo run --release -p materialcraft-cli -- render wood.mcraft wood.png --scene sphere --full --hq
cargo run --release -p materialcraft-cli -- export wood.mcraft textures --format png --depth 16
cargo run --release -p materialcraft-cli -- export my.mcraft out --set wear=0.7 # with a graph input "wear" set first
cargo run --release -p materialcraft-cli -- run my.mcraft file.exportMaterial '{"path": "my.mcmat", "size": 2048}' # for TextureCraft
cd apps/materialcraft-web && trunk serve # web build
cargo xtask ci # fmt, clippy, tests, layering, wasmYou need Rust 1.95 or newer. The app opens with the brick wall sample; File ▸ New ▸ Graph... starts from a PBR template or one of the sample materials.
Register the MCP server with Claude Code, giving it the folders it may read and write:
claude mcp add materialcraft -- /path/to/materialcraft-cli mcp --read-root /work/materials --write-root /work/materialsTo drive the running app instead, start it with --control 7878 and bridge to it:
claude mcp add materialcraft-app -- /path/to/materialcraft-cli mcp --bridge 7878The details are in docs/control-protocol.md.
MaterialCraft is under active development. ROADMAP.md has the parity estimate by area, the remaining work and what's next.
Where we are (2026-11-02): the node engine and 227 nodes (the atomic nodes including FX-Map,
SVG and Text, noises including tileable 3D ones, patterns, filters, the flood fill family,
whole-material blending and weathering), function graphs with a visual editor and dynamic
parameters, sub-graphs with exposed inputs and presets, the full editor (graph, library,
properties, 2D view with histogram, 3D view with your own OBJ/glTF meshes), .mcraft packages,
texture export, portable .mcmat materials that TextureCraft paints with (inputs stay editable
there), the browser build with file I/O, the CLI, the control channel and the MCP server
all work today. We estimate about two thirds (≈ 67%) of a material artist's daily workflow works
end to end; docs/target-app-parity.md has the breakdown.
What's missing: the rest of the node library, a GPU 3D view with tessellation and lights,
mesh-based nodes, translations and the first signed release. The ranked list is in
docs/gaps.md.
Workspace: crates/{core, image, geom, nodes, eval, formats, engine, render, automation, ui-egui}
and apps/{materialcraft, materialcraft-cli, materialcraft-web}. The egui frontend is its own
crate, so the UI can be swapped without touching the engine; docs/architecture.md
explains how it fits together.
Agent and contributor rules (clean room, the asset policy, no panics in shipped code, quality gates)
are in AGENTS.md. Every bundled asset is listed with its licence in
