I think V4 and M4 come with LOD meshes, but they only work in DAZ Studio.

Joe Public made a weight mapped M4 for Poser that uses one of the LOD meshes.

There were Reduced Resolution versions of V3 and M3, but I think they did the LOD thing for V4 and M4 instead. There were also Loretta and Lorenzo LoRez, but I don't think they were compatible with V4 and M4.
