Some time ago I've made some experiments to create a node for tiling texture patterns in Blender. Because I like carbon materials I've used this topic to create a node group that can create tiled patterns - I called it the "CW TilingTool".
The end result of my experiments is a collection of 12 carbon texture variations, called CW Carbon Collection+. The material comes with a lot of adjustable options and the uv coordinates are controlled by my TilingTool. You will find the tool as a unique node group in the node tree of the main material. If you like, you can extract the TilingTool and use it for your own materials. I would appreciate it. :)
The CW CarbonCollection works with Blenders Cycles render engine. I've created the shader tree in Blender 2.79b.
A version for Blender 2.8 will be released as soon as 2.8 gets more stable and reach the beta status.
I've prepared a detailed introduction for my material on YouTube.
