Who actually decides if a resource is originally from Bethesda if the file has been completely reworked? Does Bethesda have "agents" that compare models of each community released model to their own to see if it was copied and altered? Why even give a hoot? Oblivion is pretty old game anyways, "and released as a buggy one" too.
EDIT: Im assuming the only reason bethesda does not want people converting their meshes and textures into Morrowind (Which by the way is a 10 year old game) is because of fear of loss of revenues. Well, if a 10 year old game can threaten their "profits" then I must say that Bethesda has got to really reconsider their approach for designing new TES games. (Should of kept building onto TESIII, Improving graphics and other features, bugs bugs bugs) instead of just leaching money off their customers with a new Buggy Engine, and using the ideas from the modding industry into their new games)
I hope to see that Minotaur in Morrowind soon
