I was looking at all the figures and things, and most of them have there own unique textures...how do you make those? And also, what would you use to model your own figures for use in poser?

There are texture templates on the CD you can use with any paint program to make your own textures. Or you can download them from various sources. Modeling your own figures is possible with 3d modeling programs (Ray Dream Studio, TrueSpace, etc.), but pretty complicated. Once modeled, you need to import them, assign hierarchies for all the parts, establish joint parameters, etc.
