Question about conversion of edited models back to .mesh

[KonungGedimin]

Hello guys, how to convert back to mesh.1808282334 the edited objects (.obj, .fbx etc)? Tried converting fbx to md5mesh and then renaming to mesh.1808282334, but the game crashed at start and this ain't look like a right way to begin with.
