Project Sources
Attaches text files to a project. Every generation in that project reads them as shared context.
Shared Project Context
A project can hold Markdown or plain-text files (up to 64 KB each, 256 KB per project). Their text is sent with every new generation in the project, so constants such as a palette, a triangle budget, naming conventions, or real-world sizes are written once instead of repeated in each prompt.
Style Rules
A Style.md can set colours, materials, and finishes for a whole set. In the example shown, five prompts that never mention neon return assets with matte dark bodies and emissive neon in the file's Magenta #FF2E88 and Cyan #22E4FF. A changed source applies to generations made after the change.
Consistent Asset Sets
Game props, environment kits, and product lines depend on every piece matching. Project sources hold the palette, scale, and naming rules for a set, and every asset generated in the project follows the same text.
Sources can be added in the app, through the API, or by a coding agent through the Thrixel MCP server. Each file is screened on upload and takes effect once it is marked as applied.
