Quote - Soft Body breast effects without handlers, morphs - pure softbody dynamics.

how can it be, that we still not can do this in daz programs?

these dynamics are possible in all the games of today.

where are these dynamics in daz world?

There is this little thing you might have heard of called money.  Games have a much, much, much bigger budget than either Poser or DS development.  Also those effects are optimized for those models in that game, whereas in Poser or DS it has to be a one size fits all solution.  I hate to break it to you, but the 3D art hobbiest market has never been cutting edge.
