A high-performance rendering runtime and Blender level exporter designed for custom engine development.

Juicer is a minimal, data-driven rendering pipeline focusing on interoperability with Blender. It consists of:

1. Level Exporter: A Blender addon that packages scene data (geometry, textures, samplers, and lights) into a custom binary format (.bin).
2. Runtime: A modern rendering engine written in Odin using SDL3 GPU, capable of loading and displaying these scenes with hot-reloading support (via the exporter).

• Custom Binary Format: Optimized for fast loading with a magic header 0xB00BFACE.
• Modern Tech Stack: Built with Odin and SDL3's new GPU API (SPIR-V shaders).
• Blender Integration: One-click "Export & Run" from within Blender.
• Asset Pipeline: Automated texture handling, sampler configuration extraction, and PBR-lite material support.
• Light Support: Support for Sun, Point, and Spot lights with shadow metadata.

• Odin Compiler
• SDL3 (configured for your system)
• Blender 5.0+

1. Open Blender.
2. Install level-exporter/level_exporter.py as an addon.
3. In the Sidebar (N-panel), find the Juicer tab.

cd juicer-runtime
odin build src -out:main -debug

1. Configure the "Runtime Executable" path in the Blender Juicer panel.
2. Build your level in Blender.
3. Press F5 to export and launch the runtime instantly.

• scene.bin: Contains interleaved vertex data (Pos, UV, Norm, Tangent), object transforms, and referenced textures.
• Odin Runtime: Handles SDL3 GPU initialization, pipeline management, and scene graph traversal.

• A ton
• This is an exploratory/learning project with the purpose of expanding my knowledge of game engine architecture and data pipelines.
