World Labs Releases Marble, a Multimodal World Model for Editable 3D Worlds

A freemium model with industry-ready exports targets rapid uptake across games, VFX, VR.

Overview

  • World Labs opened public access to Marble, which generates persistent, downloadable 3D environments from text, multi-image sets, short video, panoramas, or coarse 3D layouts.
  • An AI-native hybrid editor called Chisel lets users block out structure with simple 3D primitives or imported assets, then apply text prompts to set visual style with direct object manipulation.
  • Iterative workflows now include local edits, a one-step scene expansion per world, and a composer mode that stitches multiple generated environments into larger spaces.
  • Outputs export as Gaussian splats, triangle meshes (including collider meshes), or video for use in standard game and VFX pipelines such as Unity and Unreal Engine.
  • Access is offered in four tiers: a free plan with four generations, Standard at about $20 per month, Pro at about $35 with scene expansion and commercial rights, and Max at about $95 with all features and higher limits.
