Quote - Geometry is not everything.

Are you sure? I thought it was. :blink: Well there goes string theory down the drain!

Quote - As stated above, it [a PNU] was 96 inches up to Poser 5, then 103.2 inches from Poser 6.

Yes, and the important thing to note here is that the size of a PNU did not change, that would be impossible! What changed was the size of a Poser inch. It is precisely because the size of a PNU can not change, that it is the standard.

PNU most certainly is the standard. This is because it is invariant and all other unit measurements in Poser are derived from it. It's like the wavelength of sodium light in physics, if that were to change the change would not be detectable, because all other measurements of length are derived from it, so the idea of it changing it is meaningless. The same with a PNU, if the size of a PNU were to double, that change would be absolutely undetectable, which makes nonsense out of the idea that it could change. On the other hand, the size of a Poser inch can change, as it's just a convention, not an absolute, and that's why the PNU, not the Poser inch, is the de facto standard.

BB said that "Inches are the fundamental internal unit of materials and the material system.". I'm sure he knows what he is talking about when it comes to materials. However the material room was something bolted on to Poser. Materials are not everything.
