Procedural Textures 3D Tiling with PingPong Method

Hi guys I've been doing lots of digging around these past few days and though I'd just share my results in the hopes that someone else will find it helpful.

I got the idea thanks to a comment explanation in Erindale's 'Tile any Procedural Texture' Video: youtube.com/watch

This is useful in the case that you want your procedural texture to tile in three dimensions.
