Zbrush - tileable textures for games – floor tiles

One flat plane, 1 single Poly here!

What you see underneath is only one single polygon/ flat plane with
a 1K Normal Map, Diffuse, Specular and AO rendered with PBR in Marmoset

For this texture I used Photoshop , Ndo , Ddo, Zbrush 4R7 and Marmoset 2.
