Thanks for the kind words about my textures being swiped. I'm bitter enough to be hanging out with you guys but otherwise I'm not that traumatized. All my stuff was removed from MTS2 that time around. Other textures have shown up but whatever -- I can always make more as opposed to the people who just steal things.
Poser models have limited usage in Poser for anything other than a pretty picture. You can move the models in and out of other 3D programs and they show up in a lot of computer game designs.
I'll offer up my understanding of what you can do to a Poser mesh for those that asked. DAZ3D which makes the most well known of all the Poser models allows you to make derivative models but for it to be a legal thing you have to still need the original DAZ model as your base. Here's what they say at
http://www.daz3d.com"One of the simplest ways to create a derivative model is to convert a DAZ model (typically OBJ format) to another non-Poser format, and distribute that. Beyond this, a DAZ model may be altered by adding and/or removing geometry in order to create a derivative work. Even more difficult for most users to recognize, but still detectable to trained modelers, are methods involving tools that can create a derivative mesh without transferring the polygonal layout of the original. (Many of these methods can result in a mesh which seems legitimate, often with no vertices coincidental with the original. These types of tools/methods may include: NURBS/poly conversions, subdivision/smoothing or triangulation operations, de-resing, shrink-wrapping/fitting and randomization operations.) The distribution of models created using any of the above examples is strictly prohibited, and none of these methods will result in a mesh that is not still subject to DAZ's copyright."
Most individual Poser artist have pretty much the same rules and regulations as DAZ3D.
