Thank you for the reply! I wish to import these into a metaverse platform to use as ground textures.
I can credit you in some ways, for example I can put your name in the texture description if I allow anybody else to texture their land with it.
(I'm not sure if you're ok with this, they won't be getting the original files, just an ability to apply the texture to their inworld objects.)
If I apply your texture on my land, then I could install a credits board or a "click for credit" object on my land.
There are some ways that I can't really credit, such as when people take screenshots of my land, some of these people taking screenshots may be profiting off of those screenshots in some way.
