Marble x Nuke Loads World Labs Marble Splats Straight Into Nuke's 3D Viewport

Patrick Crucke has released Marble x Nuke, an MIT-licensed Python toolset for Nuke 17.0 and later that generates World Labs Marble worlds from a text prompt or from images and pulls the resulting gaussian splats directly into Nuke's 3D viewport as PLY, without leaving the compositor. Distributed through Nukepedia and GitHub, it adds four nodes that wrap the World Labs Marble API end to end. Marble T2W handles text to world generation, Marble I2W handles image to world in single, multi-image, or reconstruct modes, with azimuth control, and its reconstruct mode accepts up to four views. Marble List browses and manages the worlds you have already generated, and Marble Splats downloads the Gaussian splats and brings them in as PLY through Nuke's native GeoImport.

Generation is one click from either a text prompt or images, the splat download is automatic, and a built-in SPZ to PLY converter. Splat resolution is configurable at full, 500k, or 100k, letting a TD trade fidelity for viewport performance when a full density world is too heavy to interact with. It runs on Windows, macOS, and Linux across Commercial, Indie, and Non-Commercial Nuke, and it stores the required World Labs API key locally so it never leaves the machine.

Nuke gained native Gaussian splatting in v17, first in the v17 beta and then extended in the 17.1 open beta with dynamic splats and basic relighting, building on the compositing workflows earlier community work had already sketched out. World Labs' Marble, meanwhile, is a generative 3D world model whose output is 3DGS, introduced with the original model, iterated through Marble 1.1 and 1.1 Plus, and opened up programmatically with the World API.

Until now, getting a Marble generation into Nuke meant exporting the splats and round tripping them through another application before they could touch the compositing graph.

The MIT license covers the plugin code only, and any world you generate remains governed by World Labs' terms, with commercial use requiring an eligible World Labs plan. Installation is manual. Copy the MarbleXnuke folder into your .nuke directory and register it in init.py, and a free World Labs API key from platform.worldlabs.ai is required.

It is available now on Nukepedia and on GitHub.
