Sorry, but after watching the tutorial on scale I just had to make a comment.
I find this method vastly easier and a much more tried and true, guess proof, way of doing it. Especially if I'm making clothes for poser models, I don't want the clothes to be 100% of the standard size of a character, I would want them to be the size of the character I modeled them for... so when I import a character into Hex I scale up using the import option and when exporting the objects I want I scale down by the inverse amount, also using the scale option.
Okay to make it simpler. When importing, say Mike 3 into Hex, I scale UP using the import option by 500%. When I've made what I want in Hex for Mike 3 I export at 0.002%. When I then load the model in Poser (usually clothing) I un-check everything but "Make polygon normals consistent". This will always give you things that are the right size, simply because you modeled them to BE that size.
I've been using Hex for over 2 years now, just to give you a little perspective. As for importing into D|S.. the simplest thing is to follow the above and then just import using the poser scale option.
Okay, I'll get off my high horse now.
Sorry if I came across as a jerk, not my intention. Just wanted to help.
