If people are directly copying Skyrim assets and putting them in Fallout 4, that is against the rules set forth by Bethesda and they'll be slapped down eventually when caught or it is pointed out to Bethesda. If a mod maker would use a Skyrim asset as an inspiration to create a work on their own so it looks exactly (or near enough) as the original so that it can be used in Fallout 4, that is perfectly fine. Inspired works are encouraged, direct copying is not - those are the rules with Bethesda games. Ah, gotcha! Thanks for clearing this up. I appreciate it.
