Nuke is widely considered better in 3D compositing than some other software for several reasons:

1. Deep Compositing: Nuke supports deep compositing, which allows for the integration of multiple 3D elements with depth information. This enables more accurate and realistic blending of CGI elements with live-action footage, resulting in seamless integration.

2. Node-Based Workflow: Nuke’s node-based workflow offers greater flexibility and control over the compositing process. Artists can create complex composites by connecting nodes that represent different operations, making it easier to manage intricate 3D scenes.

3. Extensive 3D Toolset: Nuke provides a robust set of 3D tools, including camera projection, 3D tracking, particle systems, and geometry manipulation. These tools allow artists to handle various 3D compositing tasks within a single software, streamlining the workflow.

4. High Performance: Nuke’s efficient processing capabilities and multi-threading support enable faster rendering times, even for complex 3D composites. This efficiency translates to improved productivity and shorter project turnaround times.

5. Industry Standard: Nuke is widely used in the visual effects industry and is a standard tool in many VFX studios. Its widespread adoption means that artists can easily collaborate and exchange projects with colleagues and clients, creating a unified pipeline.

6. Integration with 3D Software: Nuke has strong integration with 3D software like Autodesk Maya, allowing for seamless exchange of 3D scene data. This integration facilitates a smooth workflow between the 3D and compositing stages of a project.

7. Extensive Plugin Support: Nuke’s open architecture allows for the integration of third-party plugins, enhancing its capabilities for specific 3D compositing tasks. Artists can tailor their workflow by incorporating specialized plugins as needed.

While Nuke excels in 3D compositing, it is important to note that each software has its strengths and is suitable for different aspects of visual effects and compositing. The choice of software ultimately depends on the specific requirements of the project and the preferences of the artists and studio.
