USD-Based 3D Compositing (Beta)
We’re a new USD-based 3D system in Nuke allowing you to efficiently work with modern 3D scenes at scale. The new USD architecture brings Nuke’s 3D in line with modern standards and introduces a dedicated scene graph, new path and masking workflows, over 40 nodes, and new USD-based workflows.
We’ll be continuing to develop the new 3D system across the Nuke 14 series and, to ensure you don't lose access to any workflows you're used to, the new system work in parallel with the classic 3D system. We want to make a Nuke that works for you which is why this is a beta feature with a dedicated forum for feedback as we want to shape the future of 3D compositing in Nuke with artist feedback at its core.

These topics explain how to set up a 3D scene in Nuke's new 3D system and how to add objects and cameras in the 3D workspace. You’ll also see how to texture objects, transform objects and cameras, and render out scenes for use in other areas of your script.
The 3D workspace has many potential uses, such as projecting textures, deep compositing, particle systems, and pan-and-tile scenes. Pan and tile scenes with 2D image planes arranged into a curved shape, and then rendered out through an animated camera to give the illusion of a seamless environment.
Simple pan-and-tile scene.
The 3D nodes in Nuke appear as rounded shapes to differentiate them from nodes that perform 2D operations. You can mix 2D and 3D objects together in the node tree to create scenes. For example, you can texture a 3D object with a 2D clip or generator such as the Checkerboard node, or take the rendered output from a 3D scene and use it as a 2D background.
Note: You can't mix nodes from the new 3D system and classic 3D system, though there are a few notable exceptions to this rule, like CameraTracker and DepthGenerator. New 3D system nodes are red by default and classic 3D nodes are green.
