Late to the party but let me put in my little honest rant.  

I fully agree with the need to better recycle existing content. Some things age. For example: old textures often have burned-in highlights and that's difficult to solve. Poses on the other hand do not age. The parameters may change between figures but they still have two arms and two legs and the direction of the left forearm in xyz space does not change. There are/were perfect pose converters available that can do batch jobs. The poses section of my Project Evolution Runtime has all the poses I collected over time for V4, V3 as well as Schlabber's collections, ready to use with tweaks as needed anyway to match the character.

Obviously conversions cannot be put out as marketplace products, so even when distribution is permitted it has to be as freeware, and as such it does not exist in Rendo eyes. They rather desparately try to market a figure lacking supporting content than actively facilitate existing they do not earn direct money from. I converted manually three pose setsthree pose sets originally by Sclabber to LF/LH, just to see how that goes. It took me an hour or 2 per set to convert.    

Same for clothing conversions and clothing development. LF and LH come with a higher resolution figure as a donor. The problem is of course the geometry is the body shape and not a clothing shape, so copy by proximity leads to bad results, in particular if the figure is muscular or busty. About the bust: shape is usually altered significantly by clothing. You therefore cannot model a nightshirt and a business suit from the same mold. What Rendo lacks is thinking in a system: what would a creator need to make something to work in our system, of which the figure is just one part.   

And about figure textures: why reinvent uv mapping with every figure? After 20+ years there should be some consensus about best practice to skin a human body and spread the pelt on two square tables.  

Time to rethink ways.
