StarForge

A browser-based visual editor for Starfield's GFx interface files. Open a GFx file, edit it visually, download the result. No installs required.

---

What it does

Starfield uses Scaleform GFx files for all in-game UI. Editing them currently requires raw binary tools with no visual feedback. StarForge lets you open a GFx file in your browser, see its elements, change properties, and download the patched file.

Everything runs locally in your browser. Nothing is uploaded anywhere.

Getting started

1. Extract a GFx file from Starfield - Interface.ba2 using Bethesda Archive Extractor
2. Open StarForge and drop the file onto the editor
3. Edit elements visually
4. Download the patched file and drop it into your MO2 mod folder as a loose file override
