ArmorLab

What is ArmorLab?

ArmorLab is a free, open-source texture authoring tool from the same ecosystem as Armory3D, the Blender game engine. It was built to give artists an AI-assisted path to PBR textures without locking them into a proprietary subscription.

The tool mixes two workflows. On the AI side, you type a text prompt and ArmorLab generates a seamless PBR texture set. On the manual side, you can import a photo and convert it into a material, or build textures from scratch in a node-based editor.

It is still a young project and updates come steadily from its solo developer, but it already covers a remarkable amount of ground: generation, editing, terrain painting and export to the engines you actually use.

Key Features

• AI text-to-texture generation for seamless PBR materials
• Photo import that converts real surfaces into material maps
• Node-based material graph for full manual control
• Terrain painting with generated or imported materials
• Height map generation and normal map tools
• Export to common formats for game engines
• Open source and free, with cross-platform builds

How to get started

Head to armorlab.org and download the build for your operating system. The app runs on Windows, macOS and Linux, so platform support is broader than most commercial texture tools.

The quickest first project is a prompt: type something like 'mossy cobblestone', hit generate, and inspect the map set that comes back. Then try importing a photo or opening the node editor to see how the material is built.

• Download ArmorLab from armorlab.org
• Open the app and type a texture prompt
• Generate a seamless PBR map set
• Import a photo or open the node editor for manual work
• Export your material for your game engine

Use cases

• Generating environment textures for indie games on a budget
• Converting reference photos into usable materials
• Learning procedural material design with the node editor
• Painting terrain with layered AI-generated materials
• Building a personal texture library without subscription costs

Pricing and licensing

ArmorLab is free and open source. There are no paid tiers, no subscriptions and no watermarks; you can use the tool and its generated output in commercial projects without paying a cent.

Because it is open source, the exact license terms live on the project's GitHub repository. If you plan to redistribute or modify the tool itself, check the repository for the current license text.

Pros and cons

ArmorLab's big wins are price, openness and platform coverage. Being free and open source on Windows, macOS and Linux is rare in the texture world, and the combination of AI generation with a node editor makes it a genuinely versatile tool.

The trade-offs are maturity and polish. It is a smaller project than Adobe's suite, so expect rougher edges, fewer features and occasional bugs. AI generation quality also trails the biggest commercial services, so plan to touch up results manually.
