 Starworld is an [Overte](https://overte.org) client that renders virtual world entities inside the [StardustXR](https://stardustxr.org) compositor. It bridges Overte's entity protocol with Stardust's spatial computing environment, allowing you to view and interact with Overte domains in XR.
 
-**Current Status:** ✅ **Connection persistence is now fixed. All core entity rendering features are implemented. Color tinting and texture application are pending StardustXR API support.**

-- ✅ Dimensions (xyz size in meters)
-- ✅ GLTF/GLB model loading from local cache
-- ✅ HTTP/HTTPS model URL downloading with ModelCache (SHA256-based caching)
-- ✅ Primitive generation using Blender (`tools/blender_export_simple.py`)
