A V4 17K LOD mapped this way would be cool but I don't expect there would be any money in it for David.

What I did was used the V4 17K LOD that was free in DAZ Studio and exported it to Poser where I used the standard V4 rigging and the V4 and V4++ morphs converted with the Morph Clothes. I actually used a V4 rigging with all those hidden magnets ripped out and it still poses fine. The M4 17 K was made by creating an M4 morph for V4 and using Morph Clothes to load that on the V4 17K LOD mesh which then takes the M4 rigging and the M4 morphs converted with Morph Clothes but unfortunately it only takes V4 Male textures. A V4 17K LOD that took unimesh textures would give you both male and female characters that are nearly as light as Posette but take all the new clothing, poses, and dial-spin characters but would take all the old M3 and V3 textures.

DAZ really should have released V4 and M4 Reduced Resolution in my opinion... Stephanie Petite and David too for that matter. I nearly all cases you can render a Reduced Resolution figure side by side with the default and no one can see the difference. For firefly renders it is the poly-flow more than the mesh density and in fact making morphs for the lower mesh is easier. I have read the opinion that the standard V4 was sub-divided after the modeling had been done already. For high res you can always bake the geometry as a posed prop and sub-divide it then but why you would need to I can't imagine.
