For me it didnt work since version 10 ?! I thought maybe this could be a win32 issue, but I didnt come around to check the linux builds .. The other way round it behaves the same ( not working )
Writing LightWave files was never supported actually.
I did a quick test with the PLY file. Blender loads Houdini's PLY fine, but MeshLab does not. This might be an issue in the LightWave importer. At the top of the PLY file, there's a line like: property list uint int vertex_indices Try changing it to: property list int int vertex_indices And see if this loads into LightWave.
awong Writing LightWave files was never supported actually.

@awong I wonder then why .lwo is even in the list if it was never supported.
As for .ply:
I tried the change you mentioned and still didn't load. Same problem for either state in MeshMixer: http://i.imgur.com/tMk8bOz.png [i.imgur.com] Blender imported them fine, thought!
