Quote - This is exactly the same as has been said before.

You can pose manually, adjust morphs manually and render.

For everything else (loading morphs, clothing, hair, textures, expression and pose sets) you need to use DS4.

Not a very useful figure in Poser

Actually originally I recall you wouldn't even be able to adjust morphs in Poser, so it's a definite improvement.

And are you implying that you wouldn't be able to conform hair, clothing and such Genesis in Poser? Why not? Once it's in Poser's library as a CR2, it's a figure like any other is it not?

Yes content creators might have to create specific Poser files for hair, clothing, poses, MATs etc, but how does that differ from before? We've seen items for V4 with DS and Poser specific files for a long time since the shader system isn't compatible, etc.
