No such thing as moral rights. Law is law, rights are part of law and are based on legislation. Who knows if the DAZ EULA is actually legal anyway, many companies rely on customers not being aware of their rights.

They also rely on big-name lawyers frightening people. The bigger the company, the bigger the lawyers.

Daz may be able to copyright the V4 mesh but Dawn will have a different mesh and UV mapping. I doubt they can copyright an actual shape as such.

If they can can, then I claim copyright of the sphere and the cube and derivatives, so every one must stop using them now.
