Show HN: Build a world on your phone, explore it in XR on Vision Pro and Quest

World Builder lets you design immersive 3D worlds right from your phone, then step into them using XR on Apple Vision Pro and Meta Quest. It bridges mobile creation and spatial exploration, making world-building accessible to everyone. Whether you're prototyping game environments or crafting personal virtual spaces, the app streamlines the workflow from pocket to headset. Early feedback highlights the need for desktop render path fixes, but the core concept—seamless world creation and XR exploration—offers a compelling glimpse into the future of accessible spatial computing.

You're probably optimizing for XR, but 99% of people will experience your app for the first time on a different platform, so it's worth fixing the desktop render path.
