Nuke

Foundry Nuke's built-in 3D systems let you import FBX geometry directly into your node graph, placing real-world reference models and textured surfaces inside compositing scenes. A23D assets integrate through Nuke's classic ReadGeo workflow and through newer USD/MaterialX workflows, with PBR texture maps applied via shader and material-binding nodes.

Frequently Asked Questions

Common questions about using A23D assets with Nuke

Do I need a plugin to use A23D assets in Nuke?

No. Nuke natively supports .fbx import via the ReadGeo node. No additional plugin or bridge tool is required.

Which file format should I download for use in Nuke?

You don't need to pick a format manually - just select Nuke in the Software dropdown on the asset page and A23D delivers the right format automatically. For Nuke that's .fbx, accompanied by PNG PBR texture maps.

How do I connect A23D PBR textures in Nuke?

In modern Nuke/USD workflows, use a MtlXStandardSurface material when available and connect A23D maps to Base Color, Specular Roughness, Metalness, and Normal inputs. In classic Nuke 3D, load each PBR map via a Texture node and wire it into the matching input of a PrincipledBRDF shader, then connect the shader to an ApplyMaterial node linked to your imported geometry:

• Base Color / Albedo -> base color / diffuse input
• Roughness -> roughness input
• Metallic -> metallic input
• Normal Map -> normal map input (set vector type to Tangent Space)
• Ambient Occlusion -> multiply with Base Color

What texture resolution should I use in Nuke?

Use 2K or 4K maps for hero geometry rendered close to camera, and 1K for background reference geometry. Nuke's 3D system is optimised for compositing rather than heavy-geometry rendering, so keeping texture sizes manageable helps maintain performance in the node graph.
