v0.23.0: WebGPURenderer Spatial UI, UIExitButton Component, Documentation Overhaul

XR Blocks v0.23.0 Release Notes

We are excited to announce XR Blocks 0.23.0, introducing full WebGPURenderer support for the Spatial UI panel system and volumetric clouds, WebXR on-device compatibility for WebGPU, simulator-to-device color alignment, a standardized UIExitButton component, and restructured documentation.

Highlights

• Spatial UI on WebGPURenderer: The Spatial UI panel system now runs on THREE.WebGPURenderer via TSL (three/tsl) node materials, supporting linear and radial gradients, deterministic transparent sorting, and optimized shader compilation. Try it in your browser or headset with the live WebGPU Spatial UI sample.
• TSL Volumetric Clouds on WebGPU: VolumetricCloud now supports THREE.WebGPURenderer using a dynamically loaded TSL raymarching module.
• WebXR WebGPU Compatibility: Seamless WebXR session initiation on WebGPU with automated adapter selection and feature negotiation on supported devices.
• Simulator & Device Color Alignment: UI panel colors in the desktop simulator now accurately align with on-device appearance through corrected sRGB parsing and output color space transformations.
• Standardized UIExitButton: A new xb.UIExitButton component provides a consistent, frosted exit button for UI panels and samples with automated session termination.
• Documentation Overhaul: Reorganized getting started into dedicated Online and Local development pathways, alongside dedicated Project Setup and WebGPU guides.
