PixTract – Sprite Sheet & JSON Exporter for Blender

Create clean, game-ready sprite sheets with animation data—directly from Blender.

PixTract is a powerful and easy-to-use Blender addon designed for 2D and pixel-style creators. It allows you to export sprite sheets with accompanying JSON metadata formatted similarly to Aseprite JSON exports, compatible with the free Paper2D and PaperZD plugins for Unreal Engine or any custom pipeline you can create.

Whether you're working with Actions, Grease Pencil animations, or Shape Keys, PixTract organizes your animations into neat rows of a spritesheet and generates a clean, structured JSON file that marks the essential animation data.

🔧 Key Features:

• ⚙ Export Modes: Choose between Actions, Grease Pencil Layers, or Shape Keys for maximum flexibility.

• 📦 JSON Metadata: Automatically generates animation metadata in a format similar to Aseprite exports. Drop this JSON into Unreal Engine to automatically generate appropriate folders, files, formatted textures, and flipbooks, using Paper2D and PaperZD. (free plugins for Unreal)

• 🖼 Pixel-Perfect Output: Custom resolution controls, filter settings for Cycles and Eevee, and orthographic camera setup included.

• 📂 Organized Exports: Sprite sheets are neatly arranged with each animation in its own row, ready for use in any engine. You may specify custom filenames and output directories.

• 📌 Grease Pencil Support: Each grease pencil layer becomes its own animation row with a separate tag.

• 🔑 Shape Key Support: Animate shape keys on the Dope Sheet, and PixTract will treat each as a full animation sequence, row by row.
