World Labs Unveils Marble 1.1 & 1.1‑Plus: Hands‑On Test of Ultra‑Complex Scene Generation

World Labs announced the simultaneous launch of two generative 3D models, Marble 1.1 and Marble 1.1‑Plus . Marble 1.1 brings noticeable gains in illumination, contrast and overall visual consistency while reducing visual artifacts. Marble 1.1‑Plus is designed for large‑scale scenes, producing worlds that are bigger and more complex than previous versions.

The provider recommends new users start with Marble 1.1 for higher quality and stability, then switch to Marble 1.1‑Plus when they need to build expansive, intricate environments. Both models are accessible via an API for immediate integration.

The web portal categorises generated results into six styles—stylized, realistic, fantasy, sci‑fi, etc.—and offers two input modes. The 2D mode accepts images, videos or panoramas to generate immersive 3D worlds, while the 3D mode uses the built‑in Chisel tool to define custom layouts, supporting both external 3D files and primitive geometry.

In a hands‑on test of Marble 1.1, the authors uploaded an image and entered the prompt “A whimsical fairytale scene featuring glowing pink mushroom houses with golden windows, surrounded by lush greenery and twinkling lights in an enchanted forest.” The model produced a vivid, detailed scene matching the description. Another prompt generated a neon‑lit retro room overlooking a sunset‑lit Mt. Fuji, demonstrating the model’s ability to handle diverse aesthetics.

The platform also offers a panorama‑edit feature: after generating a world, users can select an area, supply a new prompt, and precisely modify the content. For example, the authors added a rabbit nibbling a carrot to the mushroom‑house scene.

Marble’s Expand function can seamlessly extend a world beyond its original boundaries, though this capability currently requires a paid subscription.

Testing Marble 1.1‑Plus, the team uploaded a screenshot from “Red Dead Redemption” and observed that the model produced a significantly larger and richer environment, confirming its suitability for complex scene creation.

A community case study highlighted creative professional Hugues Bruyère. He captured a real space with the portal‑cam’s 360° scan, combined the panorama with a short text prompt, and fed both into Marble 1.1. The model generated a “parallel version” of the space with more complex equipment layout, richer lighting layers, and even an entirely new exterior environment. World Labs responded, calling the result a “world portal – that’s cool!”

Another user employed Marble 1.1‑Plus to generate several moss‑covered castles, noting that the model could clearly render interior corners, a level of detail previously unavailable.

From the official site, Marble 1.1 is positioned as the new default model, replacing Marble 1.0. Its generation cost is 1500 credits, the same as the legacy model. Marble 1.1‑Plus retains the 1500‑credit base fee plus a variable cost of 0–1500 credits depending on world size, introducing the first variable‑pricing mechanism for the platform. Additionally, a “Marble 1.0 Draft” model is offered for rapid prototyping at 150 credits.

The article concludes by inviting readers to share their impressions of the World Labs update.
