Modifying Daz to make it do things that are built into Vam doesn't excite me much. Given the speed at which Daz renders animations, I don't think it adds much value. I think the whole point of soft body physics is real time animation, which Daz can't do. Yes, you could make Daz render things that look more realistic, but Vam does that part better. I think the whole dforce thing for clothes and hair was a huge mistake. Vam does it so much faster, it is usable in real time. The market Daz serves is to make it as real as possible, regardless of how long it takes to render. Dforce is basically pre-baking something to a posed figure so it looks right. Vam does that natively, provided the item has sim in it.
Don't get me wrong, I still love Daz for what it can do. I've rendered thousands of images with it, some of which I really like. I just wish I knew they wouldn't be supporting the 50x Nvidia cards for a while before I sprang for the upgrade. Works great in Vam, but GPU rendering in Iray doesn't work in Daz right now. Have to wait for a major update.
