How much more can they add to character customization?
The only things I can think of are weight and height...
And I would think that might cause clipping issues.
What you can do is you can make something called a Blendshape/Morphing.
You make the biggest armor you want, and then you shrink that down as small as you want before it starts to look funny, and the program will calculate all the shapes in between these two extremes. This how all that sliding scale stuff on character customization is done, too. So, if the smallest armor fits on the shortest option, and the biggest armor fits on the tallest option, they won't clip anywhere in between. (Although sometimes changing alot of stuff at once can be bad, it's nothing other animator's tricks can't fix.)
There are some things, like height, that can be turned into sliders easily. People have to make the tall and short options anyway, so you can just turn those into two extremes of a morph and reap the PR benefits. Other things are harder, like the size of a person's cheeks. Not only do you not necessarily have two extremes available for that, but you have to be careful that they don't clip into any of the available hairstyle options.
Because I'm such a visual person, I love visual stuff like Aion's facial customization.
But ultimately, you spend so much time looking at your character's back, other people spend so much time viewing everything from a distance, these minute facial customizations kind of get lost in the shuffle. Being able to customize your armor, the thing you can recognize from behind and at a distance would have a far greater impact, I think. If they skimped on the initial character customization, but really shone through on the armor customization, I would be happy. Edited, Aug 24th 2009 9:02pm by Zemzelette
