Ogre3D Mesh XML .mesh.xml
Ogre’s readable mesh XML, before it is compiled to binary.
What an .mesh.xml file holds
Ogre3D ships meshes as a compact binary .mesh, but its pipeline goes through a readable .mesh.xml first: vertex buffers, submeshes, bone assignments and skeleton links in plain XML. That is the form exporters emit and the only form you can actually inspect by eye.
Also seen as .mesh, .xml.
Commonly seen in: Ogre3D, Torchlight, Stunt Rally, Ogre-based engines.

Tested against a real file
The last sweep loaded ninja.mesh from Assimp test models with its 8 sidecar files through the viewer on this site: 1,008 triangles across 2 meshes and 2 materials, in 3.0 seconds. Every format's result is on the test results page, run 2026-09-08.
Files to bring with it
Drop the matching .skeleton.xml in alongside to bring the rig and animation.

Questions about Ogre XML
How do I open an .mesh.xml file?
Drop it into the viewer on this site and it opens in the browser, with the scene tree, the materials and the mesh statistics. Nothing is uploaded. If you want it in another program instead, convert it to GLB, which almost everything reads.
Is Ogre XML a good format to archive in?
Ogre XML carries geometry, materials, textures and animation, so an archive copy keeps nearly everything. The usual caveat applies: a format is only as future-proof as the readers that exist for it, and .mesh.xml is well served.
Does converting Ogre XML lose quality?
Geometry is copied vertex for vertex, so the shape does not degrade. What gets lost is whatever the target format has no field for: convert to STL and the materials go, convert to OBJ and the animation goes. The comparison table on each converter page says exactly which.
