One thing I find really cool is when 3D artists practice their skills doing little balls of various materials. I've been seeing this kind of thing for years and I thought now would be a good time to share with you some super cool material renders.
Reynante Martinez, an artist from the Philippines, comes up with some super awesome renders. These are pretty great, but I've selected only a few of his pieces. For more of his work, please visit his portfolio at ArtStation. He'll definitely enjoy it! Cheers. ;)
