It might be helpful to pin down exactly what we mean by P5-6 support. Strand-based hair is pretty ropy (no pun intended), so I don't see that as being a big factor. And the face room doesn't exactly lend itself to merchants' requirements. So, we're left with dynamic cloth and shaders (I'm not counting support for P5-6 figures, which doesn't really come under general poser sales). So, if that's the case, what it comes down to is what type of product you make. Clothes makers have the choice of supporting P4 or P5-6, or doing both. Folks who make human texs aren't going to be using the nodes to any great extent. That leaves the bulk of merchants who make sets, scenes or 'other'. And this is where the whole thing goes pear-shaped. Example - I make houses/furniture, etc. For now, I mainly stick with scanned textures of materials. When it comes to things like wood or stone, doing it in the material room takes way longer to get even an acceptable result. And by using texs, my products work for any user, in any app. I do make a lot of .mt5 files. It's by far the easiest way to apply materials without messing around with smart-propping. And daz studio uses a similar system, so I can do it for the DS version too. I also use displacement, mirrors and refraction for P5-6/DS, and the P4 crowd just don't get them. I'm sorry, but what can I do? Not use these functions at all just because they don't work in P4? But other problems come up when I go beyond the material room and into the scene itself. Lights, for instance are becoming a nightmare for me. I now have to do 3 versions - P4, P5-6 and DS. Cameras aren't so bad, although the DS users probably get the best deal there, since cameras are so much easier to use in DS, and they can be included in scene files. (I sell through DAZ and they don't accept .pz3s). All in all, it's becoming more difficult to make a complex product work in all apps, but I keep trying. I don't want to exclude any one sector of the market (yet), but the more time that passes, the more P4 looks like something from the stone age. My DS sales now make up a large part of the total, and I'm already at the point where I care less and less about P4 support. mac
