Editing XMESH files

NOTE: It is generally recommended that you use mesher to convert from BFXM to XMESH and back again for the purposes of editing. However, here is the specification for BFXM files.

Contents 1 Format for version 0.2 1.1 SuperHeader 1.2 Record Header 1.3 For each mesh: 1.3.1 Header 1.3.2 Arbitrary length attributes 1.3.3 Geometry 2 See also

Format for version 0.2
