Interesting that the responses aren't from 3D vendors, rather from people using 3D skills in general, which is great. Selling 3D models is a tough market. The product only stays in prime view for a couple of days, so you need to be "known" for people to actually want to see what you have in your store. Then you have to discount it before anyone will think about hitting the Add To Cart button. Then of course Rendo or Daz or RDNA get their cut.

Then there's the glut. Sooner or later everyone learns how to make a conforming bikini or how to change hair shades and wants to cash in. What we need is for new users to join the market faster than veteran users turn into sellers. Thankfully there are hobbyist apps like Poser and DS3 to help.
