MaterialCraft

This is a community package of MaterialCraft, maintained independently and unaffiliated with the MaterialCraft project. It repackages the official upstream Linux release build unmodified.

MaterialCraft is an open-source, native node-based material designer: build tileable PBR materials from noises, patterns and filters in a node graph, preview them live in 2D and 3D, and export the texture maps for any engine.

• Hundreds of procedural nodes: noises, patterns, adjustments, blurs, warps, normal and height tools
• Live 2D and 3D previews with physically based shading
• Export base color, normal, roughness, metallic, height and ambient occlusion maps as PNG, EXR, TGA, JPEG or TIFF; save packages as .mcraft
• Every action is a command, scriptable from a CLI, a JSON control channel and an MCP server

The headless command runner and MCP server is included: flatpak run --command=materialcraft-cli ai.storyteller.materialcraft --help

Permissions: this package uses the same sandbox as upstream's own Flatpak manifest: display (Wayland, with X11 as a fallback), the GPU device, and the Pictures and Documents folders. Files anywhere else are opened and saved through the system file chooser. No network access is granted.

Optional overrides:

• Let agents on the host reach the --control automation server: flatpak override --user --share=network ai.storyteller.materialcraft
• Open files by path anywhere in your home folder (command line, Open Recent): flatpak override --user --filesystem=home ai.storyteller.materialcraft
