What it is

Forge Material Studio is a local-first tool for authoring procedural PBR materials on the web or Windows. Its node graph builds tileable materials from components such as cloud noise, Voronoi, gradients, bricks, math, blending, and normal nodes. It can also convert PNG, JPEG, or WebP albedo images into editable base-color, height, normal, roughness, metallic, and ambient-occlusion maps. A live Babylon.js preview shows materials on a sphere, cube, plane, or production-style model, with full-result and channel views. Work can be done at 512, 1024, or 2048 pixels while preserving the source aspect ratio. Projects are stored in IndexedDB with recovery, generated-map caching, undo and redo, and keyboard save shortcuts. Exports include individual PNG maps or validated .mmpack packages with baked maps, the source graph, a manifest, and an export report. The standalone viewer opens these packages in browser memory. The tool has no account system, telemetry, or material upload service. It is free under the MIT License, which permits commercial use if the copyright and license notice remain with the software.

Spec sheet

Purpose
Forge Material Studio is a local-first tool for authoring procedural PBR materials.Read 3 Oct 2026 · github.com
Privacy
The application runs on the user's computer and has no account system, telemetry, material upload service, D1 database, or R2 bucket.Read 3 Oct 2026 · github.com
License
The project is released under the MIT License, which permits commercial use provided the copyright and license notice remain with the software.Read 3 Oct 2026 · github.com
Exports
It exports individual PNG maps or validated .mmpack packages containing baked maps, the source graph, a manifest, and an export report.Read 3 Oct 2026 · github.com
Image maps
It can turn PNG, JPEG, or WebP albedo images into editable base-color, height, normal, roughness, metallic, and ambient-occlusion maps.Read 3 Oct 2026 · github.com
Image workflow limit
When generating maps from an image, metallic defaults to a dielectric value because metal cannot be identified reliably from color alone.Read 3 Oct 2026 · github.com
Node graph
It builds tileable materials from nodes including cloud noise, Voronoi, gradient, brick, math, blend, and normal nodes.Read 3 Oct 2026 · github.com
Preview
Materials can be inspected in a live Babylon.js preview on a sphere, cube, plane, or production-style model, with beauty and individual-channel views.Read 3 Oct 2026 · github.com
Projects
Projects are saved in IndexedDB with recovery, generated-map caching, undo and redo, and keyboard save shortcuts.Read 3 Oct 2026 · github.com
Requirements
The Windows launcher requires Node.js 22.13 or newer, .NET 8 Desktop Runtime, and Microsoft Edge or Google Chrome.Read 3 Oct 2026 · github.com
Resolution
The tool supports 512, 1024, or 2048 pixel work while preserving the source aspect ratio.Read 3 Oct 2026 · github.com
Viewer
The standalone viewer opens .mmpack files entirely in browser memory.Read 3 Oct 2026 · github.com
Windows launcher
The Windows release includes an unsigned open-source launcher; the maker says it does not upload projects or textures, install a background service, or continue running after its window closes.Read 3 Oct 2026 · github.com

Strong points and limits

Strong points

  • Node graph supports procedural material authoring
  • Converts PNG, JPEG, and WebP albedo images
  • Live preview includes several shapes and models
  • Exports PNG maps and validated .mmpack packages
  • MIT License permits commercial use with notices

Limits

  • Image-derived metallic maps default to dielectric
  • Windows launcher requires Node.js 22.13 or newer
  • Windows launcher requires .NET 8 Desktop Runtime

Who it suits

Forge Material Studio suits artists and developers authoring tileable PBR materials or converting albedo images into editable maps. Windows users should check the launcher prerequisites before installing.

Verdict

Forge Material Studio combines procedural nodes, image-derived maps, previews, and package exports in a local-first workflow. Its image workflow cannot reliably identify metal from color alone, and the Windows launcher has specific runtime requirements.
