Basic procedural chamfered tiles texture.
I was looking for procedural chamfered tiles texture and couldn't find it.
This is what I was able to achieve- based on brick and wave textures. Pretty basic setup for further edition (like different and more complex materials, with glossy etc, applying "greater than" method for more than one kind of material for tiles).
Experimental displacement issue described in file- if someone will find a way to "repair" it please include it in the comments section below and I will update the file.
