I don't understand why people believe he made this. I mean, it's a render. He edited it, I guess? But people think he made the whole thing and it's like um. No. No he didn't. And whether or not you agree with rendering, he didn't make it. He edited it
he uses a program called xnalara to download the models and edit them. You can see it in his favourites. So you are right he didn't make anything here. Just rendered in blender and voilą a million views from sonic fans all over. You shouldn't take sites like this seriously since "art" on here is dubious.
