as a character maker, i can honestly say that creating products for V4 is just not worth my time anymore. sadly the sales figures no longer make V4 a viable figure to support. don't get me wrong, i love V4 and have spent an awful amount of money on V4 products. as my income from sales is what feeds me and helps pay bills, i have to create products that will give me a good return on my time invested, which means i have to create for G3F/G3M fulltime( i do manage to make a few lil props here and there when i have spare time)

sadly, the SM figures would have even less sales than V4, so they are figures that most PA's do not even consider worth touching.

tbh, in general , only PA's that make products as a hobby can think of continuing to support non-DAZ3D figures. the PA's that actually earn their living from product creation can only support figures that continue to be well supported by customers. in conversations with other PA's ( some used to create products solely for V4) the market for Poser products and V4 has shrunk to the state that they just are not worth spending the time creating products for anymore. i think it is a shame, as i love using both programs, and still use V4 a lot in my personal artwork. i prefer Firefly to 3Delight myself, but i really love Iray( just need to save up for a better graphics card to get most benefit from it! lol! )
