Hummel and TerraSame: Actually I have bad experience with such situations, especially when someone gives models for free. Most of the time there was something to hide (except in the case of Loopix or Rincewind). That is the reason why we let our artists sign documents and why we want to see images of the construction process.
Often some "artists" forgot the source of their BHV animation, of some of their textures and even meshes. They just "found" it at their hard drive. And when they have a bit of a conscience then they give it away "for free". But this means in many cases that it is not really free. People always think they do no harm, when they give it away for free, just remember those dozens of free game projects remaking a well-known game or scenario, using intellectual properties of other companies.

I would suggest to ask V-wing in person to get at least a bit more security. It can still be unsafe of course.
