DAZ 3D's stance on distributing derivative models

DAZ 3D's models may not be used to create derivative 3D models which can then be distributed in competition with the original DAZ product. (See Section 6 )

At DAZ 3D, we like to make the trade of our files, and add-on files, as free as possible. We realize that the ability for someone to diversify and improve upon our products actually makes our products more valuable, as long as these modifications are distributed in a way that doesn't circumvent the need to purchase the original DAZ product. The problems arise when someone uses our work as an unfair advantage to compete with us. As a result we have prohibited these types of actions in the DAZ License Agreement. Creation of a derivative model may involve reverse engineering, de-compiling, and/or disassembling.

Occasionally modelers are unaware that "derivative works" refers to more than just incorporating portions of DAZ geometry in a new mesh. (A method frequently referred to as "frankensteining.") "Derivative works" also refers to most of the methods that may be used to create a "new" mesh around an existing model. With the continuing evolution of new tools and methods for modeling and distributing models, it is impossible to explain specifically every possible way that a model can be used illegally in the creation of a new product. To demonstrate the range of ways this can occur, however, here are a few examples: 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. If you have any further questions about creating add-on or derivative products please contact DAZ before beginning work, as you will not be compensated for the work you have done if found in violation of DAZ's legal agreement. And if you're aware of a mesh that doesn't require but may be derived from a DAZ product, please let us know. We'd love to check it out.
