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

Commenters discussed a platform that lets users build worlds on a phone and explore them in XR. neronuser urged adding eye-catching showcases up front to demonstrate what’s possible and motivate creators, while suejunghuh0 emphasized the project’s focus on user-generated content and the need to expand mobile capabilities because most users start on phones. avaer reported concrete technical problems on desktop - an off-by-one frame rendering error and 10s load hitching on a high-end PC - and recommended improving the non-XR desktop path since many users will try the app there first. zmmmmm praised the visuals but expressed skepticism, arguing such user-built worlds often fail to sustain interest and can’t reach high-fidelity realism.

Opinion divides on whether freedom of user generation outweighs the need for curated, high-fidelity experiences. suejunghuh0 framed simpler visuals as acceptable if creativity and freedom are high, whereas zmmmmm and MiroslavPokorny questioned long-term engagement and immersion, even whimsically noting missing sensory elements like “the feeling and dynamic smell of fresh air.” Suggestions coalesced around better onboarding (showcases), more content, and technical polish, while remaining debate centers on whether this approach can avoid the pitfalls that limited earlier social VR efforts.
