That' funny because it's FROM Scifi Meshes that I've been made aware that your "good man" is using others' meshes without credit. And THAT is the problem; he's not crediting them either in the images he posts or the commentary he puts alongside.
All you have done so far is utter rhetorical nonsense and not provided any evidence that your "friend" (assuming it's not just the same guy posting under another username) is the creator of said meshes. Which, you couldn't, since he's quite plainly not.
Decrying that "it's the internet, everything is free to anyone" is utter bullshit, and points to a lack of understanding of copyrighting and the concept of intellectual property. You don't mess with someone else's mesh "all you wanted" without A) consulting said mesh creator, and/or B) giving credit where it is due. And for the record, there's no "math" involved whatsoever.
Since you haven't bothered to provide any evidence counter to what I've said thus far, I can only conclude that you are either severely deluded as to how the world works, or you are as fraudulent as your friend. After all, what has any of this got to do with YOU?
PS: I've just noticed YarYarYar has posted links verifying again that Fran444 is a fraud, among the comments on Francis' profile. Suggest you follow said links, before you attempt to make any further comments.
