SwiftUI for the editor shell for native UI workflow, while the editor components and runtime systems are rendered directly with Metal.

A modular WorkspaceToolbar and Sidebar system designed around flexible editor workflows.

USD models (.usd)

ASTC textures (.astc) are used for GPU-optimized texture storage.

CAF audio containers (.caf) are used for low-level, system-friendly audio streaming and processing.

M4A audio (.m4a) is used for compressed, distribution-ready audio assets.

JSON is used for runtime-oriented data

XML is used for hierarchical or tool-driven data

All authored data stays tool-agnostic and engine-independent.
