Marble vs LingBot-World 2: exportable 3D worlds vs real-time playable worlds
Marble and LingBot-World 2 solve different problems. Marble generates a persistent 3D world you can keep, share, and export. LingBot-World 2 streams a high-fidelity world you navigate live at 48 FPS. You can play both free on Roamscape — pick by whether you want an asset or an experience.
Short answer
Choose Marble when you want a persistent, exportable 3D scene — something you can revisit, share, or take into a downstream pipeline (SPZ, mesh).
Choose LingBot-World 2 when you want to step into a world and move through it live, at high fidelity (1664×960, 48 FPS, sub-second latency).
They aren't rivals so much as two halves of the aggregator: generate-and-keep vs enter-and-explore. Roamscape runs both, first world free.
Capability comparison
| Dimension | World Labs Marble | Reactor LingBot-World 2 |
|---|---|---|
| Core output | Persistent, exportable 3D world | Real-time navigable video stream |
| Real-time | No — generate, then explore/export | Yes — 1664×960 @ 48 FPS, <1s latency |
| Inputs | Text, image, panorama, multi-view, video | Reference image + text prompt + camera/action |
| Keep it? | Yes — SPZ, mesh, share links | No — live session, not a saved asset |
| Best for | Previs, architecture, worldbuilding, export | Live exploration, content, gaming |
| On Roamscape | Yes (free first world) | Yes (free first session) |
How to choose
- Need a file or a shareable, revisitable world? Marble.
- Want to move through a world live, right now? LingBot-World 2.
- Not sure? Run both on the same idea on Roamscape and compare.
FAQ
Can I export a world from LingBot-World 2?
No — LingBot-World 2 is a live real-time stream, not an exportable asset. For exportable SPZ or mesh worlds, use Marble.
Which is better for game environments?
Marble for exportable environment concepts and assets; LingBot-World 2 for experiencing a navigable world live. Many teams use both — Marble to build, LingBot to feel.
