Tried myself at a cool floor I had seen in an image of an Onsen. My first real Substance-material I made, besides following tutorials and breakdowns.
Please feel free to comment and critique on this! I welcome any kind of ideas or suggestions, or mention of something that doesn't work. Trying to learn the principles of a good substance :)
I couldn't get it to match the main-reference completely; especially the actual wet areas don't really match, so there's lot's of room for improvement.
