World Labs' Marble 1.1 sharpens lighting, expands worlds

World Labs is making a smart split between polish and reach: one mode cleans up the worlds people actually want to use, the other pushes into bigger, more composable environments.

• –Better lighting and contrast matter because visual coherence is the difference between a demo and something usable in production
• –1.1-Plus is the more interesting lever for builders, since larger contiguous spaces are where game, film, and simulation workflows start to compound
• –The update reinforces Marble's position as a multimodal 3D world model rather than a single-shot image-to-scene toy
• –The hard part remains consistency across edits and expansion, so the real test is whether larger worlds stay navigable without artifacts creeping back in
