Hero replacer.

 

If that's possible, then no problem. I came from modding Skyrim, and there, to upload a mod with any changes, you need to get not only the author's permission but also the permission of everyone involved in creating the mod's assets.

Yeah, there's that kind of rule. In the Heroes community, it's a bit easier; usually, they leave links to the authors and their mods, and sometimes they don't mention anyone at all. For example, in the early days of my career, I brazenly stole models from товарищ psatkha and zahar0z, and no one objected, but now I try to at least mention the authors, because it's just not right otherwise.
