 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.**
