Arc Pavers - Substance Material

Arc Raiders eh? How about some Arc Pavers... ;)
My goal was to create an arc pattern without using the one available by default in Designer, I used a tile sampler > polar - cartesian node to essentially get the same thing but with a greater degree of control. I've been wanting to use gobos for material presentation and found a great way to implement it in Unreal using the media player and light function input, gives the scene a little more life.
