Compatible Nuke versions: 17.0 or later
Compatibility: Linux, Mac, Windows
Marble x Nuke brings generative 3D world creation into Nuke. Describe a scene with a prompt, or feed it an image (single, multi-image, or up to 4 views for reconstruction), and it generates an explorable Gaussian Splat world loaded straight into the 3D viewport via GeoImport. Built for set extensions, previs environments, and 3D backplates.
Four nodes:
Marble T2W: Text-to-World
Marble I2W: Image-to-World (single / multi / reconstruct, with azimuth control)
Marble List: browse and manage generated worlds
Marble Splats: download and view Gaussian Splats as PLY
Features:
One-click world generation from text or images
Automatic Gaussian Splat download (PLY)
Built-in SPZ to PLY converter (no external Python packages)
Configurable splat resolution (full / 500k / 100k)
Works with Nuke Non-Commercial
Local API key storage that never leaves your machine
