Poly supportPartial. Poly recognizes .mesh as 3D content and processes supported files.
Indexed by PolyYes. Poly indexes filenames and visual similarity for processed geometry; scene counts are displayed in Details.
Preview in PolyPartial. Poly provides an interactive 3D preview for supported constructs.
Poly agentYes. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files.

What kind of file is .mesh?

In this page, .mesh means the OGRE serialized mesh format, rather than an arbitrary file whose name ends in mesh. OGRE's MeshSerializer imports and exports .mesh data and can optionally include material definitions; a mesh may instead rely on materials loaded separately.1 OGRE's tooling also treats skeletal animation as a related .skeleton resource.2

How do I open a .mesh file?

OGRE is the most reliable first choice for OGRE binary mesh files. Other applications may import the format or a subset of its features. Scene files often depend on sibling objects, images, materials, or animation resources; keep the original project structure available when opening one.

Poly support for .mesh

Poly recognizes .mesh 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. Poly does not promise to resolve every external asset reference from a scene or project.

An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files.

Working with .mesh

Keep the source and its referenced resources together before converting. glTF is a practical real-time delivery target, while OBJ is useful for simple geometry exchange. Both can omit application-specific scene settings, procedural materials, or animation controls.
