The EULA is Renderosity or Daz3d's standard one.. No restrictions as far as making erotic/nude scenes.  There are lots of other resources merchants use too that I'd have no way of looking up.. (Which would be stressful to say the least.) 

And you're right, we can't spend all our time looking up every resource that merchants use, that would be an impossible task. What should matter is the EULA from where I've bought the product. Otherwise it would be absolutely impossible to get anything done..
