 Starworld is an Overte client that renders virtual world entities inside the StardustXR 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:** ✨ **3D colored model rendering** with full transform, color, and dimension support! Entities render as solid GLTF models with PBR materials. See [RENDERING_FIX_SUMMARY.md](RENDERING_FIX_SUMMARY.md) for implementation details.
+**Current Status:** ✨ **3D colored model rendering with HTTP asset downloading!** Entities render as solid GLTF models with PBR materials. ModelCache automatically downloads models from http:// and https:// URLs to `~/.cache/starworld/models/`. See [RENDERING_FIX_SUMMARY.md](RENDERING_FIX_SUMMARY.md) for implementation details.
