[SMART_MATERIALS] Pavement

A smart material for pavement with 4 shapes available on the smart material. (Variant available with the sbs file if you want to make your own shapes with the rights parameters exposed). The material is made so you can change the actual shape and preserve every details with only 3 layers. (Joints, Variations, Gradients)

In the material I put some {NOTE} layers to explain what to tweak if you need to change the look easily.

The material features several options such as :
- Color/Roughness variations per tile
- Leaned tiles in and out of the ground
- Break up edges
- Cracks
- 3 kinds of patina
- Gums
- Water areas (linked to moss and lichen if needed. So lichen can grow only on water areas).
