What kind of file is .nff?

The Sense8 Neutral ASCII File Format is text interchange for polygonal geometry. Version 2 begins with the nff token, then a version line, optional viewpoint, and object specifications; comments begin with //. NFF is an ambiguous suffix used by other 3D tools too; Poly’s mapping refers to this model family.1

How do I open a .nff file?

WorldToolKit is the most reliable first choice. Other tools may import a subset of the geometry or scene constructs. Conversion to glTF or OBJ can improve interchange, but may discard materials, animation, application state, or scene relationships.

Poly support for .nff

Poly recognizes .nff as 3D content and indexes filenames and visual similarity for processed geometry. Scene counts are displayed in the Details panel. It can provide an interactive preview when the file imports successfully. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files.

Keep the original before converting. For archives and scenes, keep referenced resources together so other applications can resolve them.
