Why should it be Daz3D's responsibility to cripple their products to keep compatibility with a system that refuses to modernise? When the Platform creators absolutely flat out refuse to collaborate to that end. And at Daz3D's expense of offering a broader support base to the wider industry as a whole. 

Ahh now you are on to something. Daz is better run for profit than SM without a doubt, they have decided to dump backwards compatibility and thrust forward with their "industry standard". Good now thats out the way. Are you happy that you have to dump your investment in V6 for V7 so that you can use this new standard and enjoy the bountiful plethora of content that is totally free?
