This is one of my most impressive digital design projects. 

​

Created in Rhino3D and then rendered in Keyshot8

​

I spent hours and hours in Rhino3D building and separating layers, fine tuning details, and constantly working on the design and aesthetics. As well as learning new features and how to use them best, like "array along curve" to align all my stitching. And using my "near & end" snaps to create the perfect 3 dimensional curve that became my shoe lace. The most important detail was to break up my individual surfaces so that I could apply specific materials to certain parts, like the midsole, or the leather edge grain.

 

Once in Keyshot, I still had a lot of work to do. The default leather material is garbage, so I went to my material graph and started to edit it, adding new nodes like "Color Adjust", and "Texture Map", with "Color to Number" transitions. The last touch for the outer leather was a cellular texture displacement, plugged into the final material geometry, to give it subtle creases and ridges.

​

The final touch, and the detail I'm most excited about, is my leather edge grain. Keyshot has no suede, or "furry" material, so I was stuck completely on my own. But taking what I learned from the leather surface, I went in and created a custom material graph for my edge grain. The most important detail in the material graph was an inverted "Spots Texture" plugged into a "Displacement" node, then plugged into the material geometry.

BOOM! FURRRRRRR
